Title : Support for Path MTU (PMTU) in the Path Computation Element (PCE) communication Protocol (PCEP) Authors : Shuping Peng Cheng Li Liuyan Han Luc-Fabrice Ndifor Filename : draft-ietf-pce-pcep-pmtu-00.txt Pages : 11 Date : 2022-05-05 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.
