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
Eth
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
