Telecommunications Using PTP
PTPv2 is a next generation precision timing protocol specifically designed to
provide precise timing and sychronization over packet-based Ethernet networks.
With the advent of v2, PTP has now been adapted to meet the more sophisticated
synchronization requirements of telecommunications applications. PTPv2 captures
those requirements by providing a set of added capabilities and protocol extensions
that allow service providers to fine tune their packet-based networks for the
stringent timing and synchronization requirements of telecom-oriented applications.
New PTPv2 capabilities, such as support of unicast and telecom profile extension,
provide the higher level of accuracy and performance optimization that Telecom
requires.
