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