Forwarding and Control Element Separation (ForCES)
Applicability Statement
Abstract
The Forwarding and Control Element Separation (ForCES) protocol
defines a standard framework and mechanism for the interconnection
between control elements and forwarding elements in IP routers and
similar devices. In this document we describe the applicability of
the ForCES model and protocol. We provide example deployment
scenarios and functionality, as well as document applications that
would be inappropriate for ForCES.
