Path Computation Element communication Protocol (PCEP) extensions for
Establishing Relationships between sets of LSPs and Virtual Networks
draft-ietf-pce-vn-association-02
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.

1. Introduction
The Path Computation Element communication Protocol (PCEP) provides
mechanisms for Path Computation Elements (PCEs) to perform path
computations in response to Path Computation Clients' (PCCs)
requests.
[RFC8051] describes general considerations for a stateful PCE
deployment and examines its applicability and benefits, as well as
