           Forwarding and Control Element Separation (ForCES)
                        Applicability Statement

Abstract

   The Forwarding and Control Element Separation (ForCES) protocol
   defines a standard framework and mechanism for the interconnection
   between control elements and forwarding elements in IP routers and
   similar devices.  In this document we describe the applicability of
   the ForCES model and protocol.  We provide example deployment
   scenarios and functionality, as well as document applications that
   would be inappropriate for ForCES.
