While packet networks, for example, Ethernet, IP and MPLS networks have been optimally designed for data services, they are increasingly being called upon to support other services, including those traditionally delivered on a circuit-switched infrastructure. Many of these services and their interfaces have stringent timing requirements to ensure correct operation. This paper provides a comprehensive review of Synchronization over Ethernet techniques together with best practices and pragmatic deployment considerations. Technical background information is included to assist in the selection and engineering of appropriate timing and time distribution capabilities, for effective service delivery and transport, within communications networks.
