Service is virtual connections,connecting subscribersapplications to a networkresource

The services are implementedas IEEE 802.16 connectionswithin the wireless domain

Service type

L2 (layer 2) Service:

Transports Layer 2 (Ethernet) frames between subscriber's site and thebackbone

Can connect several subscribers sites

PPPoE: Provides connectivity between a PPPoE client ( workstations at the

subscriber's site), and PPPoE Server behind the Base Station

The frames are forwarded only between the Subscribers PCs and the PPPoEAccess Concentrator

Frames that do not contain PPPoE Ethernet type are discarded

Voice Service

VoIP service is designed for Alvarions Voice Gateways, using the proprietaryDRAP signaling protocol

Service will be for voice only and will not transfer any data

It is allowing only ARP, DHCP and DRAP discovery packets

QoS Parameters - QoS Type

QoS Type (CG, RT, NRT, BE)

The grant to transmit is prioritized inthe following order: CG, RT, NRT andBE

Different QoS profile types areavailable to support different servicerequirements:

CG :

Non Variable bit rate

Use VoIP, E1/T1

Guaranteed Rate ; delay

Service parameters:

Packet size

Sampling rate

Ver. 09-04-15

QoS Parameters - CT

CT Committed Time- RT andNRT QoS Types

The CT parameter defines thetime window where theconfigured bandwidth (CIR orMIR) is measured

Used to prioritize bandwidthallocation

A shorter CT gets higherpriority

The Values are Short (50ms),

Medium (100ms), and Long(200ms)

T0 BW?

T1 BW?

T2 BW?

CT Short (50ms)

CT Long (200ms)

It is also transmitted to all otherSUs that share the sameForwarding Rules

In this example the BroadcastRelay parameter is Enabled

VLAN tags - identify packets as beinggenerated / intended for specific groups ofusers

No VLAN - is one of the valid VLAN tags

In the backbone VPL (Virtual Private Link) tags - identify

packets as being generated or intended forspecific groups of users

No VPL tag - is also one of the valid VPL tags

VLAN to VPL translation tables must bedefined

Parameters

Reject

Part of the Network Entry process is CPE

authentication

The NPU search within its local database

whether it recognize the CPE (by MAC

Address)

In case the NPU recognize the CPE it providesthe services as defined in the NPU's local

database In case the NPU didn't recognize the CPE it

query the RADIUS server for the CPEAuthentication

The RADIUS server searches for the

corresponding service of the subscriber

In case the subscriber service is found theRADIUS server replies to the NPU with theService Profile Name, VLAN list, Access VLANConfiguration Transparent VLAN status andVLAN Classification Mode

In case the subscriber service is not found, theRADIUS server replies to the NPU with a rejectmessage

The NPU either provides the service as defined

in the service profile or sends Reject messageto the CPE, depends on the RADIUS reply

The 802.1p bits enable to mark the frame with 8 differentpriority values

The SU/NPU are capable to read these bits and based on theirvalue to associate the frame to a predefined QoS

Due to the fact that 802.1p is part of the Tagged Control Info

(TCI) field, 802.1p classification can be performed only whenthe TCI field is present
