   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.
