Comparison – SyncE, NTP, GPS, IEEE-1588

We, now have enough information to compare various synchronization methods after we went through the clock synchronization basics and the Synchronous Ethernet (SyncE), IEEE-1588 technologies. In this section we would look at various factors through which we can have a comparison – SyncE, NTP, GPS, IEEE-1588 and evaluate these technologies: Network Load: Sync-E works at…… Read More

Synchronization in Networks

(Continuing from the previous post: “Clock Synchronization in Telecommunication Networks”…) Like layers in a network, time synchronization consists of two basic layers: Phase synchronization; and Frequency Synchronization (Read more about Synchronous / Asynchronous / Isochronous / Plesiochronous) It is extremely easy to grasp this concept by considering the day-to-day questions: Why do you always make…… Read More

Time Synchronization in Telecommunication Networks

Ques: How do we synchronize the clocks across nodes in a telecom network? Answer: Instead of relying on nodes “keeping” their own sense of time, the time is “distributed” across the network hierarchy. Two promising solutions: Synchronous Ethernet and IEEE 1588 are presented in this article as well as their “combination” to deal with the…… Read More
