Multipath Time Synchronization
RFC 8039

Received changes through RFC Editor sync (created alias RFC 8039, changed title to 'Multipath Time Synchronization', changed abstract to '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.', changed standardization level to Experimental, changed state to RFC, added RFC published event at 2016-12-08, changed IESG state to RFC Published)
