9500 MPR Release 3
Alcatel-Lucent 9500 Microwave Packet Radio (MPR) is a solution for smooth transformation of backhaul networks from TDM/ATM to Ethernet. The 9500 MPR solution efficiently transports whatever multimedia traffic since it handles packets natively (packet mode) while still supporting legacy TDM traffic (hybrid mode), with the same Hardware. It also provides the Quality of Service (QoS) needed to satisfy end-users. This solution not only improves packet aggregation, but also increases the bandwidth and optimizes the Ethernet connectivity.

9500 MPR can operate in Hybrid or Packet Mode with same hardware
Enabling possibility for smooth migration from Hybrid mode to Packet mode
9500 MPR in fact is a packet-based solution designed to address in native way networks where
packet based traffic is predominant, nevertheless supporting the still present TDM/ATM traffic,
which remains vital. 9500 MPR represents the solution to allow smooth migration from the TDM
world to the packet domain in the Mobile Backhauling networks. The different incoming traffics are
converted into Ethernet packets before sending them to the internal Ethernet switch, the packet
overhead on E1/STM-1 being removed before sent in the air.
As capacity grows in the access, the requirement for higher bandwidth support will be needed in the
backhaul as well as in the metro network. Alcatel-Lucent target to address metro networks
requirement with a carrier Ethernet based solution combined with microwave packet transport. The
result in the long run is a change in the backhaul from PDH links to carrier Ethernet and in the Metro
from SDH to carrier Ethernet packet rings, and eventually to mesh networks. Exploiting the benefits

of packet architecture vs. circuit architecture (Multiservice aggregation, Service awareness, adaptive
packet transport) in accommodating broadband services, 9500 MPR allows the access equipment to
smoothly evolve in line with the new technology and related protocols (ATM/TDM/Ethernet) without
the need of renewal of an existing microwave site and protecting the already made investments.
69500 MPR is based on two separate elements:
the MSS, an indoor service switch that can also operate as a stand alone site
aggregator
the Radio Outdoor Unit, available in two options:
a) A universal ODU (ODU 300) as outdoor microwave packet transport.
b) A new multipurpose ODU, the MPT, open to be managed in the following
operating modes:
Split-Mount mode in conjunction with MSS
Standalone mode (for native Ethernet applications) connected directly to
any switch/router/base station
Moreover, ODU v1/v2 of 9400 AWY product line can be connected to MPR through a
dedicated board: operators with 9400 AWY installed base have a further opportunity
to evolve smoothly from their TDM based network to packet based network, without
changing the ODU whenever the capacity provided by AWY ODU covers customers
needs
-

9500 MPR Node supports a mix of non-protected and protected or diversity operation for single link,
repeater or star radio configurations.
The core platform, MSS4/8, with multiplexing & symmetrical x-connection functions, is able to
manage different radio directions, with the possibility to add-drop tributaries in case of local
PDH/SDH/ATM/Ethernet accesses. Core platform is based on packet technology (Ethernet Switch)
with a generic interface serial 16 x GETH between Core and peripherals.
The peripherals currently available are:
- 32 ports E1 card for PDH applications
- 16 ports E1 card for native ATM/IMA applications
- AUX card for auxiliary channels and station alarms collection
- 2 ports STM-1 for SDH applications
- Ethernet Access switch card providing 8GE i/F
- Fan unit
The Outdoor Units are connected to the MSS:
- Via Modem card for ODU 300
- Via GE port of the Core Board or of the MPT Access card for MPT
- via the AWY Access card for AWY ODU v1/2
Industry-leading scalability and density is provided in the 9500 MPR, supporting a two rack unit MSS-
8 (2 RU) or a one rack unit MSS-4 (1 RU). The MSS-8 has eight slots, while MSS-4 has four slots; in
both cases, two are allocated for core cards (control and switch module), with the remaining six (or
two) being available for user traffic adapter cards (PDH access card, SDH Access Card, ATM access
card, Auxiliary card) or for radio card (modem, MPT Access Card, AWY Access Card). Each of the
adapter card slots can be used for any adapter card type, removing the burden of complex pre-
engineering and future scenario planning.
An additional variant of MSS-4 shelf is available, called MSS-4F. MSS-4F is a 1U pizza-box indoor unit,
offering the same functionalities of MSS-4, in a fixed configuration.
9500 MPR tail, supports a mix of non-protected and protected or diversity operation for single link.
For tail applications, the MSS-1c is able to manage up to 2 radio directions, with the possibility to
add-drop tributaries in case of local PDH/Ethernet accesses. MSS-1c is based on packet technology
-
8
(Ethernet Switch) with a max capacity of 5 Gbps. MSS-1c is a half width one rack unit, offering a
compact and cost optimized solution.
The Alcatel-Lucent 9500 MPR has a compact, modular architecture, constructed to allow flexible use
of line adapter cards so operators can optimize the configuration to meet the specific requirements
of a site. With the modular architecture comes additional resiliency and flexibility. The solution can
optionally support 1+1 fully redundant configuration with core cards, PDH /SDH cards and radio
access cards; each type of card can be redundant independently. Full-protected configuration is
available, including EPS, RPS hitless, HSB and Core module protection.
9500 MPR together with all other Microwave and Optical transmission Network Elements is fully
integrated into 1350 OMS Network Management System providing all the tools required operating
the network. 9500MPR is also managed by the 5620 SAM broadband manager shared with the
Alcatel-Lucent IP product portfolios to provide full management and provision of the network at
service level.
3.1 Working Modes
9500 MPR provides, with a unique type of HW, two SW (Operational Systems) each one with its own
set of features and corresponding licenses:
Packet OS - Service Switch Aggregator
Hybrid OS - Traditional Microwave
The Service Aggregator OS allows configuring any features and any HW (included the Traditional MW
ones) supported in the release.
It is always possible to migrate (upgrade) from the Hybrid OS to the Packet OS by installing the
proper SW and upgrading the license accordingly. Over-air capacity per ODU installed is common for
both OS.

4.2 ODU 300
The ODU is a microprocessor controlled transceiver that interfaces the MSS with the antenna.
Transmitter circuits in the ODU consist of cable interface, modulator, local oscillator, up-
converter/mixer, power amplifier, and diplexer. Receive circuits consist of diplexer, low-noise
amplifier, local oscillator, down-converter/mixer, automatic gain control, and cable interface. The
microprocessor manages ODU frequency, transmit power alarming, and performance monitoring.
Power is provided by -48Vdc from the MSS to the ODU DC-DC converter. The ODU is frequency
band/TX-RX shifter dependent.
ODU 300
ODU 300 connects to the MSS via a single 50 coaxial cable, which carries transmit and receive IF
signals, telemetry signals, internal controls and ODU DC power.
4.3 MPT

4.3.1 Multipurpose radio
The innovative outdoor unit design of MPT, with GbE standard interface, opens the way to optimized
cost solution in the backhaul network.
MPT is a unique radio capable with the same hardware to be used:
- in standalone configuration (i.e. w/o dedicated indoor units), particularly useful in tail sites enabling
direct interconnection to Base Stations. In this configuration the equipment is called MPR-e.
- in split-mount configuration with MSS indoors
The MPT is a Multipurpose Packet Radio that converts an Ethernet signal into a Radio signal; it
performs not only IF/RF functionalities, but hosts the modem section too. The input interface is a
standard Giga Ethernet interface (electrical or optical).
Ethernet traffic coming from MSS or from any GEthernet generic device (base station, router,
switch..) is transported to MPT through optical or electrical connectivity.

4.3.2 Connectivity options
In case of electrical connectivity, indoor/outdoor distance up to 100m,a single CAT5 cable connects
an MPT to the MSS, or the GEthernet generic device.
In case of optical connectivity, two cables connect an MPT to the MSS or GEthernet generic device:
one cable is a 50 ohm coaxial cable to send the -48 V power supply to the MPT; the second is an
Ethernet CAT5 cable.
4.3.3 Frequency availability
MPT covers the full range of frequencies from 6 GHz to 38GHz and 70/80 GHz.
4.3.4 XPIC
Thanks to XPIC function, MPT can provide twice the capacity in one frequency channel ( Co-channel
Dual Polarized) for any combination of Ethernet, PDH and SDH up to 1Gbps.
This is very useful when access to frequency channels is limited.
Two traffic management are possible:
Configuration by default: traffic flows statically configured and separated by the user.
Operator can segregate the two radio interfaces.
In case of LAG, the mechanism is hashing the data flow. In case of hardware failure all the
traffic is redistributed to the working radio and traffic dropping is performed according to
QoS. LAG in conjunction with XPIC is providing both capacity increase and protection of the
high priority traffic
MPT being a multipurpose radio, ALU implemented an innovative solution to allow XPIC upgrade.
MPT-HC is capable to be upgraded in XPIC in field thanks to a dedicated module directly integrated in
the outdoor unit.
Several configurations are available:
2x(1+0) XPIC configuration : 2 MPT-HC interconnected together with XPIC cable. This
configuration allows operating simultaneously two links on the same radio channel, with one
using the vertical polarization, the other one the horizontal.
-
17
Double 1+1 HSB XPIC : this configuration allows to protect 100% the traffic loaded on
polarization H and V in case of failure.
Double 1+1 SD HSB XPIC : same configuration as before with 2 antennas
4.4 MPR-e
MPR-e is a new concept of radio outdoor radio.
Current MPT radio thanks to its GEthernet interface and its modem has a full flexible architecture
capable to support either split-mount architecture and stand alone architecture.
This flexibility is minimizing drastically the number of spare MPT and allowing to operator to change
his network topology based on the same hardware (full outdoor can become split-mount or the
opposite). Any GEthernet generic device (base station, switch, router..) will become capable to
transmit traffic other the air.
The Ethernet traffic is transmitted over the radio channel according to the configured QoS and to the
scheduler algorithms.

5.6.1 STM-1 mux/demux application
The STM-1 mux/demux behaves as a terminal multiplexer; it terminates or originates the
SDH frame. It multiplexes up to 63xE1 into a STM-1 electrical/ optical line connection.
Standard VC4 mapping of lower-order E1 traffic streams to/from STM-1 is applied, that
means that a VC4 directly maps up to 63xVC12 into an STM-1 signal (in turn each VC12
contains 1xE1)
Typical application is a direct connection to SDH add-drop multiplexers (ADMs)

converter will be used in configurations where single, non redundant A battery feed is used. Two
converters on the single chassis will be used when dual, redundant, A and B battery feeds are
used. In either configurations, the +24VDC to -48VDC will use a single vacant slot of the MSS chassis.
There will be no interconnection between the converter(s) and the MSS backplane. Both the +24 VDC
input and -48 VDC output will be via 2 position connectors on the front of the unit. The space
available in the MSS slot is shown below
The converter(s) will receive its input(s) from +24 VDC primary power feed(s) and the -48 VDC
output(s) will be connected to the MSS -48 VDC inputs located on the right side of the MSS chassis
via a short external power cable, providing -48 VDC to the MSS, in the same way the shelf is powered
when -48 VDC primary is used as oppose to +24 VDC.
+24V DC/DC converter can power any module in the shelf (and of course related ODU connected to
the module) up to a total power consumption of 348 watts.

9 MEF-8 and ATM
9.1 MEF-8 As described in MetroEthernet Forum, MEF-8 is a standard for implementing interoperable CES
equipment that reliably transport TDM circuits across Metro Ethernet Networks while meeting the
required performance of circuit emulated TDM services as defined in ITU-T and ANSI TDM
standards. The Circuit Emulation Service (CES) emulates a circuit network, by packetizing,
encapsulating and tunneling the TDM traffic over Ethernet.
MEF-8 Service Definitions
Alcatel-Lucent 9500 MPR implements a proprietary technique that reduces to a few percentages the
overhead improving the use on bandwidth on air when MEF-8 emulated circuits are transported. The
improvement depends on the MEF-8 payload size and frame format and in case of TDM2TDM results
in having quite the same efficiency than a traditional TDM radio.
9.1.1 BER performances
When MEF-8 Ethernet frames are transmitted through a noisy medium (e.g. the Radio Physical
Layer), bit errors may occur. If an Ethernet frame is affected by one error, this is detected and the
entire frame is dropped. This affects the TDM with a worse BER that if compared with a traditional
TDM over TDM transmission process, it is higher, multiplied by a factor that is the frame length.
In order to avoid such BER degradation a technique is implemented such as for any reasonable BER
on the Radio Channel, the TDM transported by MEF-8 CESoETH is affected by the same BER without
any multiplication effect.
-
50
9.1.2 Packet Delay Variation control A technique is implemented in order to control Packet Delay Variation (PDV) affecting MEF-8
Ethernet frames. With this technique the waiting time that affects MEF-8 Ethernet frames are not
depending on the length of the Ethernet frame.
This gives benefit in term of packet delay variation minimization, so that any kind of services (VoIP,
TDM, ATM, Ethernet) is experiencing a small cost value of PDV, independently and regardless of the
traffic load.
9.2 ATM 9500 MPR terminates the native ATM stream collected through ASAP card and to aggregate this
traffic into a unique Ethernet flow towards the air.
In the 9500 MPR node facing the Core Network, the original ATM stream can be either re-built on
ASAP card or sent as ATM PW packets through Ethernet interface.
ASAP card supports Inverse Multiplexing over ATM (IMA) v.1.1. It is possible to configure up to 8 IMA
groups on the same card; a single IMA group can support 1 to 16 E1 links.
The ASAP card extracts the ATM cells from each IMA group and discards the empty cells, optimizing
the bandwidth; it performs policing on ATM traffic and encapsulates the ATM cells into Ethernet
packets, according to RFC 4717.
At radio level, 9500 MPR manages the QoS of the original ATM stream according to the ATM services
category. Each ATM flow is assigned to a different radio queue according to its priority.
Same proprietary technique used in MEF-8 transport to improve the use on bandwidth on air, the
BER and PDV are also used to improve the ATM transport.
Two main applications are foreseen for ATM services:
ATM to ATM (ATM hand-off) 9500MPR terminates the native ATM stream collected though
ASAP board and aggregates this traffic into a unique Ethernet flow at Radio Side. In the last
9500MPR node facing Core Network, the original ATM flows are re-built on ASAP board. ATM
aggregation is performed by collecting the traffic of multiple NodeB onto a single IMA group
with a reduced number of E1 output links. In this scenario, optimization is achieved at radio
level and in terms of number of E1 interfaces towards core network.
-
51
ATM PW IMA groups are terminated by MPR network on NodeB side and ATM traffic,
encapsulated into Ethernet frames, is transported into the Core Network towards RNC. At
RNC site, MPLS gateways shall de-capsulate the ATM cells from the Ethernet frames and
rebuild the original ATM streams.

-
52
For each VP/VC defined inside an ATM interface, an ATM Traffic descriptor for the ingress
(ATM to Packet direction) and egress (Packet to ATM direction) directions could be defined,
as foreseen by relevant standards.

MDCR value: Minimum Desired Cell Rate [cell/sec] specified for UBR+. MDCR=0 for UBR
In order to further optimize the radio bandwidth, the following traffic management is
supported:
CBR: traffic is transported at the PCR (peak cell rate)
UBR+ : traffic is transported at the MDCR (Minimum Desired Cell Rate), the traffic
exceeding the MDCR (but below PCR) is transported if radio bandwidth is available
UBR: traffic is transported as best effort
Two different working modes are possible:
VCC mode (Virtual Circuit Connection): the transport of ATM traffic into Ethernet frames is
done encapsulating into the same Ethernet flow only ATM cells belonging to the same VC.
VPC mode (Virtual Path Connection): the transport of ATM traffic into Ethernet frames is
done encapsulating into the same Ethernet flow all ATM cells belonging to the same VP,
whatever the VC
Interface types supported are both UNI/NNI, to be chosen at NE level.
9.2.4 PW layer
ATM PW service support N:1 Cell Mode encapsulation with N=1.
Key parameters PWs flows are related to cell concatenation:
o Maximum number of concatenated ATM cells; this value answers to how many
ATM cells in one Ethernet frame?. Usual value are low for CBR traffic (L=2) and
higher for UBR (L=10)
o Timeout value; this value answers to how long it is needed to wait for next ATM
cell?. Usual value are low for real time traffic (1 ms) and higher for non real time
traffic (5 ms)
For each ATM PW flow, it is possible to change VPI/VCI value of the transported cells to a
different value (VPI/VCI Translation)
Ingress VPI/VCI translation (ATM-> Ethernet direction): VPI/VCI value of ATM cells
encapsulated into PW Ethernet frames is changed to a user configurable value
Egress VPI/VCI translation (Ethernet -> ATM direction) : Whatever is the VPI/VCI value
within ATM cells transported by ATM PW frame, VPI/VCI value is changed (into the ATM

Cells sent towards ATM interface) according to the configured value of related VP (in case of
VPC mode) or VC (VCC mode) of ATM interface
Capacity: it is possible to support: o Up to 48 ATM PWs for each ATM interface (IMA group) that can be supported on
the same ASAP card
o Up to 128 ATM PWs on the same ASAP card

10 Adaptive Modulation
To be able to fulfill the required quality of service (QoS) parameter of the specific applications,
together with the goal of efficient usage of the available frequency spectrum under temporal
variable channel conditions, the signal transmission parameter should be adapted to the near-
instantaneous channel conditions.
The receiver measures/estimates the communication channel conditions and sends a report to the
transmitter station. The signal transmission parameters are determined for the next transmission
according to channel quality estimation. The transmitter and the receiver must regularly synchronize
the applied communication mode.
An appropriate prediction method is needed for channel parameter estimation, because channel
quality estimation error limits the performance of the adaptive system. The most reliable approach is
based on the Signal-to-Interference-plus-Noise-Ratio (SINR), measured obtained using the Mean
Square Error (MSE).
The radio with ACM is "error-less", in other words is able to guarantee the same performances
either in case of Constant Bit Rate (CBR) payload or in case of "First Priority" payload. The error-less
concept means that a certain portion of the traffic, i.e. SDH, PDH or other-like CBR or NCBR defined
by the customer/operator as "first priority", shall be treated as the traditional traffic in SDH or PDH
system, guarantying a certain level of availability.
The remaining portion of traffic is carried with less availability, according to the link propagation
performances, guarantying the "best effort" or other objectives.
9500 MPR allows to fully exploit the air bandwidth in its entirety by changing modulation scheme
according to the propagation availability, associating to the different services quality the available
transport capacity.

10.1 Performances of Adaptive Modulation: for Flat Fading, 9500 MPR supports notch speed up to 100 dB/sec without errors on priority
traffic.
in case of Selective Fading 9500 MPR is able to provide a 40 dB notch event, thus supporting
100 MHz/sec speed without errors.
11 Synchronization
The Alcatel-Lucent 9500 MPR product family supports a full range of local and end-to-end network-
synchronization solutions for a wide variety of applications.
At the ingress of the microwave backhauling the network clock can be locked to anyone of the
following sources:
Synch-Eth
Any plesiochronous E1/T1 data link chosen from any input interface
Dedicated Sync-In port available on MPR core module for a waveform frequency signal at 2,
5, or 10 MHz
Built-in free run oscillator.
STM1 clock chosen from SDH input interface
-
56
At the egress of the backhauling network synchronization is made available through anyone of the
following:
Synch-Ethernet according to G.8261/8262
Any plesiochronous E1/T1 data link chosen from any output interface
Dedicated Sync-In port available on MPR core module for a waveform frequency signal at 2,
5, or 10 MHz.
STM1 clock chosen from SDH output interface
It is important to notice that ingress and egress methods can be freely mixed, depending on the
specific needs of the operator. So, as an example, the network clock can be locked to an ingress E1
and delivered through a Synch-Eth or BITS interface at the egress of the microwave backhauling.
On the radio channel, a 9500 MPR transfers the reference clock to an adjacent MPR device through
the radio carrier frequency at physical layer. This method offers two main advantages:
No bandwidth is consumed for the synchronization distribution
Total immunity to the network load.
End-to-end scenarios where time-of-day/phase alignment are requested are fully supported, as 1588
PTP v2 is delivered transparently by MPR across the microwave backhauling network.

MPR deployment in mobile backhauling
Both for Hybrid and Packet working modes, the Clock can be received at hand-off or delivered at the
cell site. Synch-Eth, E1, PDH, SDH and BITS clock modes are available.
9500 MPR has an embedded reference clock which is distributed to each board of the network
element. Such clock is generated in the Clock Reference Unit (CRU) of the core card (controller).
Clock source selection and distribution
The availability of the Clock in the Network represents the most common scenario, characterized by
a time source available at the ingress of the microwave backhauling network, derived from the
primary reference clock.

Synchronization (frequency) is delivered to the cell site using any of the options available on MPR,
depending on the operators need. Worth repeating ingress and egress methods can be mixed (i.e.

12 Ethernet Features
12.1 MAC Switching embedded Level 2 Ethernet The switch is capable to evaluate the destination address of each frame received and to transmit the
individual frames to the correct egress port according to information contained in a database
"address resolution table" and associated to destination address. If the switch does not know on
which port to forward the frame (destination address is not present in "address resolution table"), it
sends the packet on all ports (flooding). The switch performs half transparent bridge functionality
that is to filter the frames which destination is on the segment (port) where it was received.
12.2 Level-2 Addressing
-
59
The address management function is performed in the switch through the address table (Level-2
Table) that can manage up to 16384 entries in MSS-4/8, 8192 entries in MSS-1c. This means that the
maximum number of MAC addresses supported is 16384 for MSS-4/8 and 8192 with MSS-1c.
New entries are automatically learned when packet is received on port.
These entries can be created or updated by the Equipment.
The aging process periodically removes dynamically learned addresses from the "address resolution
table".
Learning is based on Source MAC Address and VLAN ID.
It is possible to combine this function with the static configuration of the registration entries. For any
valid incoming packet, the Source MAC Address is associated to the VLAN ID (directly from the packet
or through VLAN Tables) and used to search the proper tables.
If a match is not found, the new address is learned and associated with the ingress port of the
packet. If a match is found, no further action is taken for learning.
The Destination MAC Address along with the VLAN ID is used as a search key for the packets output
port.
If a match is found then the packet is switched out on the matched port, otherwise, if the match is
not found, then a Destination Lookup Failure (DLF) occurs and the packet is switched out on all ports
that are members of the VLAN, except that one which has received the packet in ingress.
12.3 Flooding If the switch does not know on which port to forward the frame (destination address is not present in
"address resolution table"), it sends the packet on all ports (flooding). By default the flooding is
enabled on all ports and doesnt require any CT/NMS setting. Nevertheless using the cross
connections capability is possible to restrict the flooding only on some ports.
12.4 Half bridge functionality The switch performs half transparent bridge functionality (address learning to filter the frames which
destination is on the segment where it was generated).
12.5 Summary of Ethernet Features Supported
-
60
12.5.1 IEEE 802.3x Flow control
In case of incoming Ethernet traffic leading to exhaustion of buffers on input queues, PAUSE frames
are transmitted from the switch to remote peer in order to slow down the traffic (if the peer
supports flow control).
In the other direction, when the switch receives a pause frame on a specific port from peer
equipment, the switch stops the packet transmission on that port until receives again a pause frame
with resume transmission command.
Flow control to be fully effective (no packets lost inside the network) requires that all devices in the
end-to-end path support flow control.
The flow control function is supported only when the capability is full duplex.
The flow control setting on the switch ports linked to user Ethernet ports must be consistent with the
setting on the user ports.
Flow control is supported on MSS-1c, on 1 port, in full duplex asymmetric Tx mode, meaning that the
switch will be able to transmit PAUSE frames, but will ignore received PAUSE frames.
Flow control is not supported on MPR-e.
12.5.2 Asymmetric Flow control
This features on switch port based, allows of enable the pause frame only in transmission or receiver
side.
In the first case the switch can generate pause frame toward peer but is not able to stop
transmission traffic when receives a pause from peer.
In the second case, asymmetric receive flow control enabled, the switch when receives a pause
frame stops the transmission but is not able to transmit pause frame toward the peer.
The asymmetric flow control setting on the switch ports linked to user Ethernet ports must be
consistent with the setting on the user ports.
12.5.3 802.1Q VLAN management
Deleted: will be supported on MSS-1c
in future release. And
-
61
The port-based VLAN feature allows of partition the switch ports into virtual private domains.
According to the type of site configuration and cross-connections setting this feature is properly
managed by the software. For example, if all traffic from one Ethernet port must be forwarded only
in one radio direction is good to enable the traffic exchange only between these ports.
The IEEE 802.1Q tag VLAN feature can be enabled including between the other the stripping or
adding of the TAG and VLAN lookups in addition to MAC lookups (this feature between the other can
be useful for re-route TMN traffic to the controller).
The IEEE 802.1Q tag VLAN feature can be enabled or disabled (be transparent for the VLAN) including
between the other the stripping or adding of the TAG and VLAN lookups in addition to MAC lookups
(this feature can be useful to logically break a physical LAN into a few smaller logical LAN and to
prevent data to flow between the sub-LAN), dropping NON-VLAN Frames.
12.5.4 Link Aggregation (IEEE 802.3ad)
Link Aggregation allows one or more physical links to be aggregated together to form a Link
Aggregation Group, such that a MAC Client (CES, VLAN Management, etc.) can treat the Link
Aggregation Group as if it is a single link.
Link Aggregation provides the following:
Increased bandwidth: The capacity of multiple links is combined into one logical link
Link protection: The failure or replacement of a single link within a Link Aggregation Group
does not cause failure from the perspective of a MAC Client.
Load sharing: MAC Client traffic may be distributed across multiple links.
Automatic configuration: Link Aggregation Groups are automatically configured and
individual links are automatically allocated to those groups relying on the Link Aggregation
Protocol.
Static configuration: Link Aggregation Groups are statically configured by the operator.
Link aggregation is not currently supported on MSS-1c.
12.6 Ethernet OAM (IEEE 802.3ag)
-
62
Ethernet OAM is a set of procedures for maintenance and troubleshooting of point-to-point and
multi-point Ethernet Virtual Connections that span one or more links. It is end-to-end within an
Ethernet network. The following figure shows a network comprising of multiple domains within the
metro network.

The customer subscribes to the services of a provider, who in turn subscribes to the services of two
operators. Every domain has its own NMS. There are two planes. Vertical plane in red shows the
OAM entities across different domains. Horizontal plane in blue has various OAM entities (MEPs
and MIPs) within a domain. The following figures show the cross-section across the vertical OAM
plane and the horizontal OAM plane respectively. The vertical plane figure shows a single monitored
path for each administrative domain; the horizontal plane figure shows two monitored paths for the
same administrative domain.

12.7 Ethernet Ring Protection (ITU-T G.8032v2)
-
64
ERP allows a simple, Carrier Grade and reliable packet protection in ring topologies. It is applicable to
Full Microwave Rings only.
ITU-T G.8032v2 ERP filled the gap in Carrier grade Ring protection schema. (x)STP in fact has been
developed for LAN environments and it is not employed anymore in new network deployments for
its lack of determinism (depending on the position of root bridge) and scalability (BPDU needs to be
processed in each node, MSTP is complex to operate, Per-VLAN STP is not standardized and scalable)
in Carrier networks.
With reference to the following network scenario:
the following specifications apply:
The ring is implemented by east and west facing radio directions
Traffic can follow on both ring directions: Clockwise direction & Counter-clockwise direction
Protection is triggered by physical criteria (no protocol intervention)
Protection is based on R-APS messages sent on both sides of the ring by the nodes detecting the
failure. Traffic is redirected by each node of the ring locally, ensuring parallel processing to speed up
protection time.
G.8032v2 algorithm operates on VLAN, regardless the type of traffic transported: TDM (TDM2TDM
and TDM2ETH) and Eth (Multiple CoS and services) traffic types can be protected
Traffic flows (any type/priority) can be allocated on both ring directions to exploit the maximum ring
bandwidth in normal conditions for best effort traffic and to limit packet delay when traffic enters
from different points of the ring.
Ring protection supports only the ODU300 and the 1+0 unprotected configuration
G.8032v2 is supported on both MSS-8 and MSS-4
Synchronization is managed through SSM messages (Synchronous Ethernet).
In the following picture two instances of G.8032v2 ERP are used in the ring.
On each instance multiple VLAN can be mapped. Instances can be configured to block VLAN on
different nodes/ports of the ring, effectively allowing traffic to flow on different directions according
to the VLAN they are mapped in.
-
65
The remaining variants of the ring protection (MPT, Radio LAG, Fiber, etc.) will be supported in the
next release .
12.8 Other features
Port Segregation: all traffic received/transmitted from one user Ethernet port or radio
direction can not be exchanged with specific user Ethernet ports/radio directions
Per flow policer: ingress rate limiter per VLAN, dropping the traffic exceeding a given CIR
value
Broadcast storm control: ingress rate limiter on broadcast traffic
Multicast storm control: ingress rate limiter on multicast traffic
-
66
MAC address access control list: only packet with SA inside a given list are transmitted
towards the radio
These features are not supported by MPR-e.
12.8.1 Stacked VLAN (Q-in-Q): 802.1ad
The switch supports double tagging according to 802.1ad, in particular:
adding a service VLAN on the ingress traffic
pbits value of service VLAN is a)user configurable b)same value of customer VLAN.
The EtherTypes supported are:
EtherType 0x8100
EtherType 0x9100
EtherType 0x88A8
This feature is not supported by MPR-e.
12.8.2 VLAN swap
Every incoming frames on a given user having VLANID xxx is remarked with VLANID yyy without
changing the priority (.1p bits).
This feature is not supported by MSS-1c and MPR-e
12.9 Ethernet QoS The Ethernet switch provides a Quality of Service mechanism to control all streams. If by CT/NMS the
QoS is disabled all traffic inside the switch has the same priority, this means that for each switch port
there is only one queue (FIFO) therefore the first packet that arrives is the first that is transmitted.
12.9.1 Traffic priority
In the switch the QoS assigns the priority for each packet according to information in:
Port-based: the same priority is assigned to each frame arriving at the given ingress port;
IEEE std 802.1p: the packet is examined for the presence of a valid 802.1P user-priority Tag. If the
tag is present the correspondent priority is assigned to the packet;
-
67
MAC based: the MAC destination address and VLAN ID are used to determine the priority for
each packet;
DiffServ: each packet is classified based on DSCP field in the IP header to determine the priority;
By CT/NMS the priority can be chosen between 802.1p or DiffServ for each Network Element.
12.9.2 IEEE 802.1P QoS configuration
When 802.1p QoS mechanism is adopted the reference is the standard "IEEE 802.1D-2004 Annex G.
User priorities and traffic classes that defines 7 traffic types and the corresponding user priority
values.
By CT/NMS is possible to configure the mapping 802.1p value to queue inside the switch (except for
MSS-1c).
When an incoming packet is not 802.1p it is assigned to the lowest priority queue.
12.9.3 DiffServ QoS configuration
When DiffServ QoS mechanism is adopted the classification uses the DS field of the IP packet header.
By CT/NMS is possible to configure the mapping DS field value to queue inside the switch (except for
MSS-1c). When an incoming packet has not DiffServ valid value it is assigned to the lowest priority
queue. IPv6 TOS classification is supported as well.
12.9.4 Congestion management
In case of traffic congestion is possible to choose between Random Early Detection (RED) or tail drop
algorithm before the congestion becomes excessive.
12.9.5 Quality of Service
Quality of service of CORE card: The Quality of Service feature of the Ethernet switch provides eight
internal queues for each port to support eight different class of service (COS). For each egress port
according to the method of QoS classification configured in the switch, the packets are assigned to
specific queue.
-
68
High priority traffic is served starting from Queue 8 to 6, while the remaining five queues are shared
by all generic Ethernet flows according the default and fixed classification mechanism configured by
CT/NMS.
In MSS-1c, classification services is slightly different to stick with specific requirements of the tail.
L2 switch in MSS-1c provides 4 internal queues per port
All TDM flows are assigned to highest egress priority queue (Q4)
Ethernet flows are assigned based on 802.1p or Diffserv information.
For MPR-e , the 3 first queues are dedicated to TDM2TDM, TDM2ETH and TMN traffic. TDM2TDM
and TDM2ETH traffic management will be supported in future release.
5 next queues are dedicated to Ethernet traffic.
For MPR-e, the Ethernet queues can be configured in HQP (starting from queue#5) in strict priority
algorithm to guaranty real time transport such as VoIP

Two types of scheduler algorithms are possible:
Deficit Weighted Round Robin (DWRR); the weights determine the number of blocks (not the
number of packets) that each queue can send at each algorithm round.
Strict Priority (SP) or High Queue Preempt (HQP); guarantee that when the queue with higher
priority is not empty, it is immediately served. The primary purpose of the strict priority
scheduler is to provide lower latency service to the higher CoS classes of traffic.
