Abstract

In the hybrid fiber/coax (HFC) architecture, a number of 500-2000 subscribers in the CATV (community antenna TV) network may cause serious collisions during the request phase. In this paper, we propose a new network architecture which using an intelligent node (IN) to stand for a group of subscribers to request the demand resources. The intelligent node has the ability to reduce the collision probability as well as the collision resolving period. The simulation results shown that the throughput and average buffer delay obtained by the proposed architecture is better than that of the standard architecture
