PCEP Extension for Distribution of Link-State and TE Information.
Daniele Ceccarelli, Dhruv Dhody, Young Lee · 1998
In order to compute and provide optimal paths, Path Computation Elements (PCEs) require an accurate and timely Traffic Engineering Database (TED). Traditionally this TED has been obtained from a link state (LS) routing protocol supporting traffic engineering extensions. This document extends the Path Computation Element Communication Protocol (PCEP) with Link-State and TE Information.
