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).
