A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Path Computation Element Working Group of the IETF.
Title : The use of SVEC (Synchronization VECtor) list for Synchronized dependent path computations
Author(s) : I. Nishioka, D. King
Filename : draft-ietf-pce-pcep-svec-list-03.txt
Pages : 15

A Path Computation Element (PCE) performing dependent path
computations, for instance calculating a diverse working and
protected path not sharing common network points, would need to
synchronize the computations in order to increase the probability of
meeting the working and protected path diversity (or disjointness)
objective and network resource optimization objective. When a PCE
computes multiple sets of dependent path computation requests
concurrently, it is required to use Synchronization VECtor (SVEC)
list for association among the sets of dependent path computation
requests. SVEC is also applicable to end-to-end diverse path
computation across multiple domains. This document describes the
usage of SVECs in the SVEC list and diverse path computation
guideline, for the synchronized computation of dependent paths.
