RFC 5812: Forwarding and Control Element Separation (ForCES) Forwarding Element Model, J. Halpern, J. Hadi Salim2010-03-01T23:00:00-00:00This document defines the forwarding element (FE) model used in the Forwarding and Control Element Separation (ForCES) protocol. The model represents 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 an FE, what capabilities these functions support, and how these functions are or can be interconnected. This FE model is intended to satisfy the model requirements specified in RFC 3654. [STANDARDS-TRACK]
