ITU-T profiles for IEEE 1588 WHITE PAPER
With the transition from time-division multiplexing (TDM) to packet switched networks, the need to transport time/synchronization over a packet network became a necessity. IEEE 1588 (IEEE Std 1588™-2008 [1]), also known as Precision Time Protocol (PTP), is becoming the main protocol to transport precision time/phase/frequency over packet networks. IEEE 1588 [1] defines a protocol to distribute synchronization over packets networks; it is a very precise protocol with many features and options that can be used to address a wide range of applications. Not all the options and features are needed for a particular application and therefore IEEE 1588 developed the concept of profile. Clause 19.2.3 of IEEE 1588 [1] defines a profile as follows:
“The purpose of a PTP profile is to allow organizations to specify specific selections of attribute values and optional features of PTP that, when using the same transport protocol, inter-work and achieve a performance that meets the requirements of a particular application. A PTP profile is a set of required options, prohibited options, and the ranges and defaults of configurable attributes.”
