End-to-end OAM between demarcation points
• Clear demarcation between provider’s and Customer’s networks –
quickly determine responsibility of service affecting problems
• Operations Administration & Maintenance (OAM)
Allow for end-to-end fault management and performance monitoring
• Traffic management starting at customer premises
• Service Level Agreement Monitoring
Customers demand proof of the SLA contract

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
slide 15
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)

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
RT, VoIP

• Based on leaky bucket algorithm with CIR parameter
