A lot of network devices can process packets in a parallel manner. The Forwarding and Control Element Separation (ForCES) model [RFC5812] presents a formal way to describe the Forwarding Plane's datapath with Logical Function Blocks (LFBs) using XML. This document describes how packet parallelization can be described with the ForCES model.

            Forwarding and Control Element Separation (ForCES)                          Packet Parallelization


   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).
