Abstract:
The PCE is a core component of Software-Defined Networking (SDN)
systems. A PCE-based Central Controller (PCECC) can simplify the
processing of a distributed control plane by blending it with
elements of SDN without necessarily completely replacing it.
Segment Routing (SR) technology leverages the source routing and
tunneling paradigms. Each path is specified as a set of "segments"
encoded in the header of each packet as a list of Segment Identifiers
(SIDs).
This document specifies the procedures and Path Computation Element
Communication Protocol (PCEP) extensions when a PCE-based controller
is also responsible for configuring the forwarding actions on the
routers, in addition to computing the paths for packet flows in the
SRv6 (SR in IPv6) network and telling the edge routers what
instructions to attach to packets as they enter the network. PCECC
is further enhanced for SRv6 SID allocation and distribution.
