Industry Analysis• “…the total amount of bandwidth required is increasing

(i.e., 20%-40% annually).”• “…total network budgets continue to increase. We expect

network costs to grow from 25% of the IT budget in 2000 to 32% in 2005. These pressures will force IT planners to increase the use of various quality-of-service (QoS) mechanisms (e.g., queuing, TCP rate control) through 2005.”

• “As the downturn fades, organizations will feel an increasing need to boost their productivity by adding new applications, putting pressure on bandwidth and requiring more intelligent switches.”

Quality of Service or Class of Service?

• Can’t be exclusive of one another• “Quality of Service” has a broad definition

– It is a measurement of how well a network behaves

– It includes categorizing a particular connection or flow

• “Class of Service” has a more granular definition– It implies the categorization of services into distinct classes that can

be treated individually, relative to each other

• The interpretation of either term can depend on the priorities of the service provider, network manager, or the end user– Predictable network characteristics or preferential traffic treatment?


Levels of Quality of Service

• Guaranteed Services– Provides circuit-switch-like services

– Reserves or guarantees necessary bandwidth

• Tiered Services– Provides traffic prioritization by separating traffic by criticality

– Treat important traffic better; less important traffic worse

– High probability traffic will get through but with no “guarantees”

• Best Effort– “What you see is what you get”

– Needs bandwidth


Why Should a Network Have QoS?

• Critical business transactions and applications run over the network infrastructure

• Deploy converged voice, video and data applications in a reliable and cost effective manner

• Bandwidth is not an unlimited or inexpensive resource• There will always be places in your network where there is

congestion• Over-engineering is costly and over-subscription inevitably

leads to poor network performance• Ensure network availability for mission critical applications,

devices, and users• Optimize network resources and reduce overall IT costs

cascade stacking design – Unlike other stackable

switches, Business Policy Switches have no single point of failure stack (non-matrix)

• Hot Swappable Switches• –48V DC-to-DC converter

module must be ordered with BPS to connect to BayStack 10 Power Supply System for RPSU support

Distributed MultiLink Trunking

• MultiLink Trunking Provides High Bandwidth and Fault Tolerance

• Stack connections to servers and the network center is protected, even if one switch should fail (Distributed MultiLink Trunking)

• Load-balancing, fail-over protection for uninterrupted access to servers or network center

SMLT Link Aggregation

• Split MultiLink Trunking– A Fresh approach to the spanning

tree problem– Current network rules mean that one

connection must be blocked.– Both Links are active

• Advantages– Fail-over reduced to <1sec– None wasted - You can use what you

pay for!

IST


Virtual LAN (VLAN) Support

• Total of 256 VLANs per stack that can be:– 802.1Q VLAN ID

– Port based

– Protocol sensitive

– MAC SA based

• Shared and individual (for duplicate MAC address) VLAN learning is supported (SVL & IVL)


Security

• Support for Extensible Authentication Protocol (EAP)

– Prevents network connectivity without password authorization for added security and control in physically non-secure areas

– Authenticated users are placed in dynamically assigned VLAN

– Interoperates with Microsoft Windows XP– Based on IEEE 802.1x standard

• Only major vendor with SNMP v3 support – User authentication, Data encryption

• Distributed Access List Security– SNMP/Web/Telnet

• RADIUS Authentication Support • BaySecure

– MAC address based security

Unauthorized Unauthorized USERUSER

Security Filters


Traffic Policing

• Allows provisioning of different levels of service by limiting traffic throughput at ingress port of BPS– For example, if you set a port to certain speed such as 10 Mbps, all

traffic under 10 Mbps on that port will pass and traffic that exceeds 10 Mbps on that same port is dropped.

– Useful for service providers that want to control bandwidth to their customers

• Policing is implemented through the use of filters and filter attributes


Software v2.0 Release

• Three new Gigabit MDAs that support 8 output queues and support traffic shaping.

– BPS2000-1GT 1-port 1000BASE-TX MDA– BPS2000-2GT 2-port 1000BASE-TX MDA– BPS2000-2GE 2-port Small Form Factor GBIC MDA

• With the two-port small form factor GBIC MDA, you can plug up to two small form factor pluggable GBICs.

– 1-port 1000BASE-SX Small Form Factor GBIC (LC connector)– 1-port 1000BASE-SX Small Form Factor GBIC (MT-RJ connector)– 1-port 1000BASE-LX Small Form Factor GBIC (LC connector)

• Shaping on IP Classified Flows – Smooth IP traffic from egress (exiting) ports of the new Gigabit Ethernet MDAs– The primary customers are service providers or carrier customers that are

selling Ethernet in place of traditional Frame Relay, ISDN, or ATM WAN access solutions, for simple end-to-end Ethernet service


New Gigabit MDAs

2-port Small Form FactorGBIC MDA

1-port 1000BASE-TX MDA

CWDM Support

• With CWDM (Coarse Wave Division Multiplexing), a customer can dramatically increase the bandwidth supported over a single fiber

– Instead of 1 gigabit per fiber connection, with a CWDM GBIC, eight wavelengths can be supported per fiber. In other words, eight gigabits of traffic can be supported across one single mode fiber.

• With the BPS2000-2GE 2-port Small Form Factor GBIC MDA, BPS can support up to two CWDM GBICs

• There are eight different wavelength GBIC options for 40 km and eight different wavelength GBIC options for 70 km that will work with the two-port small form factor GBIC MDA (see ordering information for details)

Business Policy SwitchQuality of Service


IP Quality of Service (QoS)

• QoS provides the ability to read, alter, prioritize and tag or mark IP traffic based upon information imbedded in Type of Service (ToS) field in the IP header as established by the IETF committee

• DiffServ is based upon Type of Service (ToS) field • Employs a DSCP-to-802.1p mapping table via hardware based

ASICs• DiffServ used over IntServ due to superior scaling capabilities• The ability to prioritize traffic allows for:

– Better voice quality when using IP telephony– Better quality streaming videos and video conferencing– The ability to offer levels of service based upon bandwidth allocation

Video Server Desktop I2004 IP PhoneFTP Server


Differentiated Services (DiffServ)How it works …..

• DiffServ provides QoS by simplifying resource reservations to a small number of service classes provisioned throughout the network.

• Consistent per hop behavior (PHB) for aggregate flow classes is defined in the core of the network

– Pre-defines QoS service level for all traffic in the aggregate flow

– Bandwidth Requirements

– Delay sensitivity

– 4 Standards – Expedited Forwarding, Assured Forwarding, Discard Eligible, Class Selector

• Traffic at the edge is classified according QoS service levels – marking DSCP to match service class

Queuing Function• Up to eight hardware-based queues for Normal or Expedited

classes of service per egress (exiting) port (with BPS-1GT, -2GT, or -2GE MDA)

• Prioritization established through packet classification or explicitly through:

– ToS / DSCP marking – IP SA/DA or subnets– TCP/UDP source/destination port/port range– 802.1p priority bits– Ingress source port– IP protocol ID (e.g. TCP, UDP, IGMP)– EtherType (e.g. IP, IPX)– VLAN ID

• Strict Priority and Weighted Round Robin (WRR)– High priority queue is strict priority, remaining are WRR– WRR prevents Normal priority traffic from being starved by Expedited traffic (on a per-

packet basis)
