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. Contents 1.
