Abstract:
   Traditionally, the BNG provides aggregation of fixed access nodes
   (such as DSLAM and OLTs) over Ethernet and provides subscriber
   management and traffic management functions for residential
   subscribers. The BNG has however evolved to become a multi-access
   edge device that also provides termination of subscribers over
   fixed-wireless and hybrid access. An overall architecture and
   interfaces required between separated control and user-plane for a
   multi-access BNG are described in draft-wadhwa-rtgwg-bng-cups-
   01.txt. This document discusses requirements for protocol between
   subscriber-management control-plane and user-plane for BNG to
   achieve separation.
