Abstract

   This document describes how to extend the ForCES LFB topology across
   FEs by defining the Inter-FE LFB Class.  The Inter-FE LFB Class
   provides the ability to pass data and metadata across FEs without
   needing any changes to the ForCES specification.  The document
   focuses on Ethernet transport.
