Abstract:
The Path Computation Element (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 and
without necessarily completely replacing it. Thus, the LSP can be
calculated/set up/initiated and the label forwarding entries can also
be downloaded through a centralized PCE server to each network device
along the path while leveraging the existing PCE technologies as much
as possible.
This document specifies the procedures and 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 a segment routing (SR) network and telling the
edge routers what instructions to attach to packets as they enter the
network. PCECC is further enhanced for SR-MPLS SID (Segment
Identifier) allocation and distribution.
