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

• 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

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)

•
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
•

Diagnostic Loopbacks
• Layer 1 Loopback – loopbacks traffic
from Rx to Tx
• Out of service – disrupts service
• Cannot traverse Ethernet bridge
Tester
• Performed on all traffic
No Layer L2
Loopback
• 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)

LT Req
LT Rep
• 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
