Abstract:

   In order to compute and provide optimal paths, Path Computation
   Elements (PCEs) require an accurate and timely Traffic Engineering
   Database (TED).  This Link State and TE information has previously
   been obtained from a link state routing protocol that supports
   traffic engineering extensions.

   Link-State (LS) and Traffic Engineering (TE) Information can also be
   carried in Path Computation Element Communication Protocol (PCEP)
   using exensions known as PCEP-LS.  This document provides further
   experimental extensions to collect Link-State and TE information for
   optical networks.
