Amendment Standard - Active - Draft.
This amendment to IEEE Std 802.1AS™-2020 specifies protocols, processes, procedures, functions, mechanisms, and managed objects to enable fault-tolerant timing by increasing the availability of the time and adding time integrity. This is achieved using two or more generalized Precision Time Protocol (gPTP) domains, multiple time distribution paths, the local oscillator clock, and a time selection function with individual processes for times that have interdependencies and times that do not have interdependencies. Fault-tolerant timing includes fault-tolerant time generation and distribution.
