Title : ForCES Model Extension
Author : Evangelos Haleplidis

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 that 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 a forwarding
element (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 updates RFC5812 and extends the model to allow complex
datatypes for metadata, optional default values for datatypes,
optional access types for structures and fixes an issue with Logical
Functional Block (LFB) inheritance. The document also introduces two
new features a new event condition BecomesEqualTo and LFB properties.
