              ForCES Logical Function Block (LFB) Library
                      draft-ietf-forces-lfb-lib-08

Abstract

   This document defines basic classes of Logical Function Blocks (LFBs)
   used in the Forwarding and Control Element Separation (ForCES).  The
   basic LFB classes are defined according to ForCES FE model and ForCES
   protocol specifications, and are scoped to meet requirements of
   typical router functions and considered as the basic LFB library for
   ForCES.  The library includes the descriptions of the LFBs and the
   XML definitions.
