  13. Service Delivery Tools

  14. 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

  15. 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)

  16. 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 CoS 1 EVC CoS2 CoS 4 EVC1 UNI UNI UNI EVC EVC CoS 3 EVC

  17. 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 RT, VoIP service Q1 Strict Priority Q2 Q3 Data Services Q4 WFQ Q5 Q6 Q7 Q8

  18. PSN PSN Resiliency – Link Protection • Link Aggregation (802.3ad) based • Both uplink redundant ports connected to a single upstream device • Both uplinks are considered as a single logical entity • Dual homing • Uplink redundant ports are connected to two different upstream devices • Network switch over is performed by control protocol such as STP (Ethernet) or RSVP-TE (VPLS/MPLS) Single homing Gigabit Ethernet CPE 1 or 4 Dual homing • Switch criteria: • Loss Of Signal (LOS) indication • Manual Gigabit Ethernet CPE 1 or 4

  28. Fault Propagation Network port failure Failure propagated to user port • ‘Link down’ status on the Network port causes ‘link down’ status on the user port. • In case of multiple user ports cause ‘link down’ status on all user ports or part of them according to parameter • ‘Wait to restore’ parameter - defines the time between network port becoming ‘up’ and restoring user port link up CPE Switches to alternative path Packet Switched Network Eth/IP/MPLS CPE E-NTU X X

  29. Diagnostic Loopbacks • Layer 1 Loopback – ETX loopbacks traffic from Rx to Tx • Out of service – disrupts service • Cannot traverse Ethernet bridge • Supported on any ETX port • Performed on all traffic of the ETX port • Loopback activation is via management not OAM protocol • Layer 2 Loopback – ETX loopbacks traffic and swaps MAC Addresses • ETX replaces Source Address with Destination Address • Can traverse Ethernet bridges • Performed per VLAN (or EVC) Tester No Layer L2 Loopback ETX Tester With Layer L2 Loopback
