Abstract:
The Path Computation Element (PCE) provides path computation
functions in support of traffic engineering in Multiprotocol Label
Switching (MPLS) and Generalized MPLS (GMPLS) networks.
The Source Packet Routing in Networking (SPRING) architecture
describes how Segment Routing (SR) can be used to steer packets
through an IPv6 or MPLS network using the source routing paradigm. A
Segment Routed Path can be derived from a variety of mechanisms,
including an IGP Shortest Path Tree (SPT), explicit configuration, or
a Path Computation Element (PCE).
Since the SR does not require signaling, the path maximum
transmission unit (MTU) information for SR path is not available.
This document specify the extension to PCE communication protocol
(PCEP) to carry path (MTU) in the PCEP messages.
