           Forwarding and Control Element Separation (ForCES)
                         Packet Parallelization

Abstract

   Many network devices support parallel packet processing.  This
   document describes how Forwarding and Control Element Separation
   (ForCES) can model a network device's parallelization datapath using
   constructs defined by the ForCES model (RFC 5812) and controlled via
   the ForCES protocol (RFC 5810).
