                       Implementation Report for
           Forwarding and Control Element Separation (ForCES)

Abstract

   Forwarding and Control Element Separation (ForCES) defines an
   architectural framework and associated protocols to standardize
   information exchange between the control plane and the forwarding
   plane in a ForCES network element (ForCES NE).  RFC 3654 has defined
   the ForCES requirements, and RFC 3746 has defined the ForCES
   framework.

   This document is an implementation report for the ForCES Protocol,
   Model, and the Stream Control Transmission Protocol-based Transport
   Mapping Layer (SCTP TML) documents, and includes a report on
   interoperability testing and the current state of ForCES
   implementations.
