Abstract

   This document introduces the Forwarding and Control Element
   Separation (ForCES) architecture and defines a set of associated
   terminology.  This document also defines a set of architectural,
   modeling, and protocol requirements to logically separate the control
   and data forwarding planes of an IP (IPv4, IPv6, etc.) networking
   device.
