Carrier Ethernet Industry Voices

New Peer Reviewed Paper:  Ethernet Service Protection

Over the last few years, packet switching technologies, such as Ethernet and MPLS, have been widely adopted by the industry as the technologies of choice to replace existing networks based on circuit-switching technologies, such as SONET/SDH and ATM. 

Published at the Ethernet Academy:  Synchronization in packet-based mobile backhaul networks by Antonis Karvelas

Abstract:  Mobile backhaul networks are evolving from circuit switched to packet switched technologies to meet exploding demand for bandwidth in both core and access networks. A prerequisite in the evolution to packet-based backhaul in mobile backhaul networks is the ability to deliver carrier grade synchronization over the packet network to remote wireless base stations and access platforms.

The MEF has been instrumental by initiating and successfully driving formal efforts to define Carrier Ethernet and the services delivered by Service Providers.    Without the five attributes defined by the MEF which distinquish Carrier Ethernet from common LAN-based Ethernet ~ Standardized services, Scalability, Reliability, Quality of Service (QoS) and Service management ~ Service Provider's would likely continue to deploy an infrastructure that  necessitates greater infrastructure, management and expense.   That said, Ethernet services can be carried over SDH/SONET and  IP/MPLS.    In the case of IP/MPLS this is a significant advantage in that Ethernet links can be transported as "pseudowires" using MPLS label switched paths (LSPs) inside an outer MPLS "tunnel".     There is so much more that could be said here...
