Title : IGP Extensions for Segment Routing Capable PCE Discovery
Author(s) : S. Sivabalan, et al
Filename : draft-sivabalan-pce-disco-segment-routing
Pages : 6

When a PCE is a Label Switching Router (LSR) participating in
Interior Gateway Protocol (IGP), or a server participating in IGP,
its presence and path computation capabilities can be advertised
using IGP flooding. Such IGP extensions exist for OSPF and ISIS to
advertise several such capabilities. Segment Routing (SR) leverages
the source routing and tunneling pardigms in which a node steers a
packet through the network using segments. A segment can be an MPLS
label or IPv6 header with a new extension. In SR networks, a PCE can
be used to compute paths using SR PCEP extension. This document
specifies additional capability to advertise a PCE that supports the
new SR PCEP extension.
