Abstract:
This document defines a method for transporting timing messages, such
as Precision Time Protocol (PTP) or Network Time Protocol (NTP), over
a Multiprotocol Label Switched (MPLS) network. The method
facilitates efficient recognition of timing packets to enable their
port level processing in both Label Edge Routers (LERs) and Label
Switched Routers (LSRs).
The basic mechanism is to transport timing messages inside "Timing
LSPs", which are dedicated MPLS Label Switched Paths (LSPs) that
carry only timing, and possibly related Operations, Administration
and Maintenance (OAM) or management packets, but do not carry
customer traffic.
Two encapsulations methods are defined. The first transports UDP/IP
encapsulated timing messages directly over the dedicated LSP. The
second transports Ethernet encapsuled timing messages inside an
Ethernet pseudowire.
