Real life example of carrier challenges for delivering a ubiquitous ethernet service to a band headquarters and its branches
The headquarters and downtown branches are in fiber fed offices, which are easy to get to, but the suburban branches can only be reach via copper
The out of state branches are in another carriers territory and must be fed using leased capacity (DS3)
The carrier (and end-user) want a uniform service across all these branches/headquarters regardless of first mile technology – the only difference between sites should be the Ethernet service bit rate
Extending the reach of the provider’s network over a variety of access technologies
Consistent Ethernet service across different access technology

14. Service Delivery Tools

15. 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. 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. 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, Bytes, 1xByte granularity
EIR – Excess Information Rate Rate, 1Kbps granularity
EBS – Excess Burst Size, 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

18. Quality of Service Class of service management: Shaping Queuing
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 ,000 bytes, 1xbyte granularity

19. 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
