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 multipath
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 multipath
approach can significantly contribute to clock accuracy, security,
and fault tolerance.  The multipath approach that is presented in
this document enables backward compatibility with nodes that do not
support the multipath functionality.

This document is a product of the Timing over IP Connection and Transfer of Clock Working Group of the IETF.

EXPERIMENTAL: This memo defines an Experimental Protocol for the
Internet community.  It does not specify an Internet standard of any
kind. Discussion and suggestions for improvement are requested.
