Abstract:
Clock synchronization protocols are very widely used in IP-based
networks. The Network Time Protocol (NTP) has been commonly deployed
for many years, and the last few years have seen an increasingly
rapid deployment of the Precision Time Protocol (PTP). As time-
sensitive applications evolve, clock accuracy requirements are
becoming increasingly stringent, requiring the time synchronization
protocols to provide high accuracy. This memo describes a multi-path
approach to PTP and NTP over IP networks, allowing the protocols to
run concurrently over multiple communication paths between the master
and slave clocks, without modifying these protocols. The multi-path
approach can significantly contribute to clock accuracy, security and
fault tolerance. The multi-path approach that is presented in this
document enables backward compatibility with nodes that do not
support the multi-path functionality.
