In order to provide greater scalability, network confidentiality, and
service independence, Segment Routing (SR) utilizes a Binding Segment
Identifier (BSID), as described in RFC 8402. It is possible to
associate a BSID to an RSVP-TE-signaled Traffic Engineering (TE)
Label Switched Path (LSP) or an SR TE path. The BSID can be used by
an upstream node for steering traffic into the appropriate TE path to
enforce SR policies. This document specifies the concept of binding
value, which can be either an MPLS label or a Segment Identifier
(SID). It further specifies an extension to Path Computation Element
Communication Protocol (PCEP) for reporting the binding value by a
Path Computation Client (PCC) to the Path Computation Element (PCE)
to support PCE-based TE policies.
This document is a product of the Path Computation Element Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
