    PCEP Extension for Distribution of Link-State and TE information for

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.
