Abstract

   This document describes how to extend Path Computation Element (PCE)
   Communication Protocol (PCEP) association mechanism introduced by the
   PCEP Association Group specification, to further associate sets of
   LSPs with a higher-level structure such as a virtual network (VN)
   requested by clients or applications. This extended association
   mechanism can be used to facilitate virtual network control using PCE
   architecture.
