Title : ForCES Model Extension

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). RFC5812 has defined
the ForCES Model provides a formal way to represent the capabilities,
state, and configuration of forwarding elements within the context of
the ForCES protocol, so that control elements (CEs) can control the
FEs accordingly. More specifically, the model describes the logical
functions that are present in an FE, what capabilities these
functions support, and how these functions are or can be
interconnected.
RFC5812 has been around for two years and experience in its use has
shown room for small extensions without a need to alter the protocol
while retaining backward compatibility with older xml libraries.
This document extends the model to allow complex datatypes for
metadata, optional default values for datatypes and optional access
types for structures. The document also introduces three new
features, bitmap as a new datatype, a new event condition
BecomesEqualTo and LFB properties.
