The Path Computation Element Communication Protocol (PCEP) has been
extended to support stateful PCE functions where the stateful PCE
maintains information about paths and resource usage within a
network; however, these extensions do not cover all requirements for
GMPLS networks.
This document provides the extensions required for PCEP so as to
enable the usage of a stateful PCE capability in GMPLS-controlled
networks.
This document is a product of the Path Computation Element Working Group of the
IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
