Abstract

[RFC5440] describes the specifications for the Path Computation Element Communication Protocol (PCEP). PCEP specifies the communication between a Path Computation Client (PCC) and a Path Computation Element (PCE), or between two PCEs based on the PCE architecture [RFC4655]. PCEP interactions include path computation requests and path computation replies.

            Use of the Synchronization VECtor (SVEC) List for                 Synchronized Dependent Path Computations

Abstract

   A Path Computation Element (PCE) may be required to perform dependent    path computations.  Dependent path computations are requests that    need to be synchronized in order to meet specific objectives.  An    example of a dependent request would be a PCE computing a set of    services that are required to be diverse (disjointed) from each    other.  When a PCE computes sets of dependent path computation    requests concurrently, use of the Synchronization VECtor (SVEC) list    is required for association among the sets of dependent path    computation requests.  The SVEC object is optional and carried within    the Path Computation Element Communication Protocol (PCEP) PCRequest    (PCReq) message.

   This document does not specify the PCEP SVEC object or procedure.    This informational document clarifies the use of the SVEC list for    synchronized path computations when computing dependent requests.    The document also describes a number of usage scenarios for SVEC    lists within single-domain and multi-domain environments.
