Internet Engineering Task Force (IETF) W. Wang Request for Comments: 6956 Zhejiang Gongshang University Category: Standards Track E. Haleplidis ISSN: 2070-1721 University of Patras K. Ogawa NTT Corporation C. Li Hangzhou DPtech J. Halpern Ericsson June 2013 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. Status of This Memo This is an Internet Standards Track document.
