14 slide 14 Confidential Service Delivery Tools

15 slide 15 Confidential Ethernet Forwarding Model Classification - flow is created according to VLAN/pbit/TOS/DSCP/Port Policing per flow - 2 rate 3 color policer is assigned to the flow Mapping flows to classes of service – service differentiation SPVLAN manipulation – Identifies flow and CoS in the network Scheduling - Strict priority and WFQ combinations Shaping – Conforms egress traffic to specific rate Forwarding model is not based on bridging but rather on flow assignment (e.g. VLAN xconnect) Bridge will be available in v2.0

16 slide 16 Confidential Ethernet Forwarding Model II Flow based forwarding of traffic per service identifier: CVLAN ID CVLAN Pbit Customer DSCP/TOS Subscriber port Treatment of control protocols Peer, Tunnel, Discard Traffic can be tagged, double tagged or untouched per flow Marking of pbit on SP tag can preserve CVLAN pbit (copy function) or edit new value Support of 30 EVC per unit and up to 240 traffic profiles instances (64 distinct profiles)

17 slide 17 Confidential Bandwidth Profiles Flexible Policer based on 2 rate 3 color token bucket Conform, Drop Eligible, Drop Bandwidth profile per service identifier CVLAN ID CVLAN Pbit Customer DSCP/TOS Subscriber port Bandwidth Profile attributes CIR – Committed Information Rate, 1Kbps granularity CBS – Committed Burst Size, 2048-32000 Bytes, 1xByte granularity EIR – Excess Information Rate Rate, 1Kbps granularity EBS – Excess Burst Size, 2048-32000 Bytes, 1xByte granularity Typical Services VoIP: CIR/CBS according to rate sold, EIR/EBS=0 High Priority Data, CIR/CBS with typically high EIR/EBS (2xCIR) Best Effort: CIR/CBS=0, EIR/EBS according to rate sold UNI EV C UNI EV C UNI EVC1 CoS 1 CoS 4 CoS2 CoS 3

18 slide 18 Confidential Quality of Service Class of service management: Traffic can mapped to eight queues for eight classes of service Strict priority for low delay low jitter applications such as VoIP WFQ scheduling for Improving fairness for non critical traffic Combination of WFQ and Strict Priority Shaping Smoothes egress traffic from network port Based on leaky bucket algorithm with CIR parameter Queuing Flexible Combination of WFQ and Strict Priority Per queue WFQ configurable weight from 1 to 32 Per queue configurable length 64-32,000 bytes, 1xbyte granularity Congestion treatment WRED – Congestion avoidance Q1 Q2 Q3 Q4 Q5 Q6 WFQ Strict Priority Q7 Q8 RT, VoIP service Data Services
