Abstract:
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.
SR enables any head-end node to select any path without relying on a
hop-by-hop signaling technique (e.g., LDP or RSVP-TE).
It depends only on "segments" that are advertised by Link-State IGPs.
A Segment Routed Path can be derived from a variety of mechanisms,
including an IGP Shortest Path Tree (SPT), explicit configuration, or
a PCE.
Since SR can be applied to both MPLS and IPv6 forwarding plane, a PCE
should be able to compute SR-Path for both MPLS and IPv6 forwarding
plane. This document describes the extensions required for SR
support for IPv6 data plane in Path Computation Element communication
Protocol (PCEP). The PCEP extension and mechanism to support SR-MPLS
is described in RFC 8664. This document extends it to support SRv6
(SR over IPv6).
