Question 1:



I am a service provider with a SONET
network deploying Ethernet over SONET.




Should I replace my Ethernet over SONET
with COE over SONET ?




If so, why ?

I have Ethernet over SONET (EoS).

Should I replace my EoS with COE over SONET ?


Ethernet over SONET (EoS) MSPP Challenges

1.
EoS doesn’t support aggregation


EoS is a port
-
based service


Ethernet switch added for aggregation

2.
EoS service bandwidth dictated by SONET


EoS bandwidth in 50Mbps STS increments


Other bandwidth rates waste SONET bandwidth


COE over SONET with VCG Sharing on Packet ONP (PONP)


COE supports service aggregation


Aggregates EVCs or OVCs



COE aggregates EVCs on same SONET VCG


Can achieve 100% bandwidth utilization
