Abstract

   This document describes extending the ForCES LFB topology across FEs
   i.e inter-FE connectivity without needing any changes to the ForCES
   definitions by defining the Inter-FE LFB.  The Inter-FE LFB provides
   ability to pass data, metadata and exceptions across FEs.  The
   document describes a generic way to transport the mentioned details
   but focuses on ethernet transport.
