A Broadband Network Gateway (BNG) in a fixed wireline access network
is an Ethernet-centric IP edge router and the aggregation point for
subscriber traffic. Control and User Plane Separation (CUPS) for such
a BNG improves flexibility and scalability but requires various
communication between the User Plane (UP) and the Control Plane (CP).
 China Mobile, Huawei Technologies, and ZTE have developed a simple
CUPS control channel protocol to support such communication: the
Simple Control and User Plane Separation Protocol (S-CUSP). S-CUSP is
defined in this document. 

This document is not an IETF standard and does not have IETF
consensus.  S-CUSP is presented here to make its specification
conveniently available to the Internet community to enable diagnosis
and interoperability.
