Path Computation Element communication Protocol (PCEP) extensions
for Establishing Relationships between sets of LSPs and Virtual
Networks
draft-leedhody-pce-vn-association-08
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.
