PCEP Extension for Distribution of Link-State and TE information for
Optical Networks
draft-lee-pce-pcep-ls-optical-10
Abstract
In order to compute and provide optimal paths, Path Computation
Elements (PCEs) require an accurate and timely Traffic Engineering
Database (TED). Traditionally this Link State and TE information has
been obtained from a link state routing protocol (supporting traffic
engineering extensions).
This document extends the Path Communication Element Communication
Protocol (PCEP) with Link-State and TE information for optical
networks.
