A stateful Path Computation Element (PCE) maintains information about
Label Switched Path (LSP) characteristics and resource usage within a
network in order to provide traffic-engineering calculations for its
associated Path Computation Clients (PCCs).  This document describes
general considerations for a stateful PCE deployment and examines its
applicability and benefits, as well as its challenges and
limitations, through a number of use cases.  PCE Communication
Protocol (PCEP) extensions required for stateful PCE usage are
covered in separate documents.

This document is a product of the Path Computation Element Working Group of the IETF.
