    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.},
