Abstract:
This document defines the method for transporting Timing messages
such as PTP and NTP over an MPLS network. The method allows for the
easy identification of these PDUs at the port level to allow for port
level processing of these PDUs in both LERs and LSRs.
The basic idea is to transport Timing messages inside dedicated MPLS
LSPs. These LSPs only carry timing messages and possibly Control and
Management packets, but they do not carry customer traffic.
Two methods for transporting Timing messages over MPLS are defined.
The first method is to transport Timing messages directly over the
dedicated MPLS LSP via UDP/IP encapsulation, which is suitable for
MPLS networks. The second method is to transport Timing messages
inside a PW via Ethernet encapsulation, which is suitable for both
MPLS and MPLS-TP networks.
