Abstract

The deployment of B-ISDN (Broadband integrated service digital network) must overcome the difficulty of constructing an infrastructure for the last mile to end users in metropolitan networks. Broadband communication over CATV networks may be one of the most attractive approaches to realize the last mile network architecture. To overcome the difficulties in serving reverse-link integrated service traffic in tree-and-branch CATV networks, we propose a novel protocol known as the Spatial-Group Randomly Addressed Polling with Reservation (SR-GRAP) protocol. Under the potential large service area and the large number of end-users, we demonstrate its significant efficiency for reverse link multiple access communication in CATV networks, so that a good variety of constant/variable bit rate applications with different Quality of Service (QoS) and multimedia LAN/MAN communications can be fully supported.
