[RFC3746] specifies the Forwarding and Control Element Separation (ForCES) framework. In the framework, Control Elements (CEs) configure and manage one or more separate Forwarding Elements (FEs) within a Network Element (NE) by use of a ForCES protocol. [RFC5810] specifies the ForCES protocol. [RFC5812] specifies the Forwarding Element (FE) model. In the model, resources in FEs are described by classes of Logical Function Blocks (LFBs). The FE model defines the structure and abstract semantics of LFBs and provides XML schema for the definitions of LFBs.

            Forwarding and Control Element Separation (ForCES)                   Logical Function Block (LFB) Library


   This document defines basic classes of Logical Function Blocks (LFBs)    used in Forwarding and Control Element Separation (ForCES).  The    basic LFB classes are defined according to the ForCES Forwarding    Element (FE) model and ForCES protocol specifications; they are    scoped to meet requirements of typical router functions and are    considered the basic LFB library for ForCES.  The library includes    the descriptions of the LFBs and the XML definitions.
