Synchronized Transportation by “Synchronous Ethernet”

This paper presents how Synchronous Ethernet can be use in both the Ethernet and synchronization architectures, and how this helped development in standardization bodies. Standardization allows the key building blocks of Ethernet silicon and specific timing devices to be developed, which allows a robust system implementation to be constructed while allowing interworking with and migration from existing SONET/SDH-based transport infrastructure. The transport architecture and some synchronization distribution problems to many endpoints where mobile backhaul and TDM emulation occur. Finally, results are shown that indicate a very high level of performance is achievable with Synchronous Ethernet not subject to the normal packet delay variation and traffic load conditions that can occur in packet based networks.
