Since Ethernet or packet based networks operate asynchronously, many of the traditional applications that depend on synchronization are not supported. Designers increasingly need to combine services supplied by data efficient packet networks with the ones served by the large installed base of traditional SONET/SDH networks. Both Synchronous Ethernet (SyncE) and packet timing using the IEEE 1588 protocol offer viable solutions in unifying service delivery over both networks. Read this application note to discover methods for transporting synchronization and potential synchronized timing implementations.
