Abstract

   This document describes how to extend the Forwarding and Control    Element Separation (ForCES) Logical Functional Block (LFB) topology    across Forwarding Elements (FEs) by defining the inter-FE LFB class.    The inter-FE LFB class provides the ability to pass data and metadata    across FEs without needing any changes to the ForCES specification.    The document focuses on Ethernet transport.
