Implementation Report for
Forwarding and Control Element Separation (ForCES)
Abstract
Forwarding and Control Element Separation (ForCES) defines an
architectural framework and associated protocols to standardize
information exchange between the control plane and the forwarding
plane in a ForCES network element (ForCES NE). RFC 3654 has defined
the ForCES requirements, and RFC 3746 has defined the ForCES
framework.
This document is an implementation report for the ForCES Protocol,
Model, and the Stream Control Transmission Protocol-based Transport
Mapping Layer (SCTP TML) documents, and includes a report on
interoperability testing and the current state of ForCES
implementations.
