What is the Business Case?

Strong growth of DSL subscribers ~200 million in 2007

expected to grow to 364 million in 2011*

What are they used for?• Internet hi-speed access (residential customers)

• Added value (residential market - video, gaming, etc.)

• Voice over IP services

• IP VPN services for business customers* Source: Infonetics Research, Broadband Aggregation Hardware and Subscribers Market Share and Forecasts 4Q07

We have the technology and the infrastructure which provide higher Bandwidth….

…what else can we do with it?• Carrier & Utilities Market (Railways, Highways, CCTV)

• Leased line services (E1/T1, n x 64 kbps), FR

• Ethernet services for Business customers

• Cellular backhaul for 2G/2.5G and 3G networks

LA-210 Working Modes

• LA-210 is designed to deliver business-class Ethernet services, using two operational modes:

• Bridge mode• VLAN aware/unaware

• VLAN stacking

• Supports 64 VLANs out of full range (1-4095)

• Static/Dynamic MAC learning with aging

• 1K of MAC entries

• Flows – customer traffic is mapped to the Ethernet flows (EVCs) using the following:

• Port-based

• Customer VLAN ID

• Customer VLAN priority

• DSCP

• IP Precedence

• On user ingress – traffic is mapped to Service by one of the following criteria:

• P.Bit

• VLAN ID

• IP Precedence

• DSCP

Policer Per Service/Flow Bandwidth Control

• Traffic policing per ingress Service• Dual Token Bucket mechanism

(CIR+CBS, EIR+EBS) per policer

• 2 rate (CIR/EIR), 3 color (Green/Yellow/Red) marking:• Green:0 to CIR – always

‘respected’

• Yellow: between CIR to EIR – Will be respected until the queue reaches a predefine threshold, then it will discarded

• Red: above EIR – always discarded

Queues/Egress Rate Limit/Scheduler

• MNG Traffic Always get the Highest Queue

• 4 Queues on the Egress (4th Q has the Highest Priority)

• Each Queue can be configured as Strict/Weighted Fair Queue (100 Weights)

• Egress Rate Limit per Queue/Port (DSL)

• Scheduling:

• Strict on Top of WFQ

• WFQ (Weight of Q) ÷ (Weight of all Q)

• Example: Queue #2 40 ÷ 80 = ½Queue #1 30 ÷ 80 = 3/8Queue #0 10 ÷ 80 = 1/8

Continuity Check (CC) OAM

• CC OAM Defined per EVC, allows for one-way connectivity monitoring

• Loss of Continuity (LOC) is declared (only at the sink side) upon 3.5 seconds without receiving CC OAM frame

• Loss of Continuity (LOC) is cleared upon sink receiving 2 CC OAM frames within a window of 3.5 seconds

• Upon CC failure

• Send trap

• Update active alarm log

• Update statistics

• Optional uplink switch-over

Loopback (LB) OAM

• Defined per EVC, allows for non-intrusive loopback (round trip) connectivity monitoring

• Sent from MEP, looped by either MEP or MIP

• LB Failure is declared upon 2 seconds without receiving the specific LB OAM frame

• Upon LB failure

• Send trap

• Update active alarm log

• Update statistics

• Optional uplink switch-overService OAM MEPs and MIPs

Diagnostic Loopbacks

• Layer 1 Loopback – loopbacks traffic from Rx to Tx

• Out of service – disrupts service

• Cannot traverse Ethernet bridge

• Performed on all traffic

• Loopback activation is via management not OAM protocol

• Layer 2 Loopback – loopbacks traffic and swaps MAC Addresses

• Replaces Source Address with Destination Address

• Can traverse Ethernet bridges

• Performed per VLAN (or EVC)

No Layer L2 Loopback

Link Trace (LT) OAM

• Once a problem detected with CC or LB than LT can be used to pin point where the problem is

• OAM is sent to the final MAC address and all nodes in the path that receive the LT request send back LT response, this way the failure point is found

• Can be used also the resolve disputes when more than 1 network is used
