Abstract:
This document specifies extensions to the Path Computation Element
Communication Protocol (PCEP) to support Segment Routing (SR) with a
focus on the use of Segment Identifiers (SIDs) and SR-Algorithms in
Traffic Engineering (TE). The SR-Algorithm associated with a SID
defines the path computation algorithm used by Interior Gateway
Protocols (IGPs). This document proposes an approach for informing
PCEP peers about the SR-Algorithm associated with each SID used, as
well as signaling a specific SR-Algorithm as a constraint to the PCE.
The mechanisms for specifying SR-Algorithm constraint is allowing
refined path computations that meet specific operational needs, such
as low-latency or high-bandwidth paths mostly based on operator-
defined criteria using Flexible Algorithms.
