Hi PCE WG participants,

Here's a revived PCE draft to support impairment computation. Your comments are always appreciated.

Abstract:
   As an optical signal progresses along its path it may be altered by
   the various physical processes in the optical fibers and devices it
   encounters. When such alterations result in signal degradation,
   these processes are usually referred to as "impairments". These
   physical characteristics may be important constraints to consider in
   path computation process in wavelength switched optical networks.

   This document provides PCEP extensions to support Impairment Aware
   Routing and Wavelength Assignment (IA-RWA) in wavelength switched
   optical networks.
