Abstract
In the hybrid fiber/coax (HFC) architecture, over several hundreds subscribers in CATV (community antenna TV) network may cause serious collisions. 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 IN has the ability to reduce the collision probability as well as the collision resolving period. The simulation results show that the proposed architecture in terms of throughput, buffer delay, and fairness outperforms the standard architecture.
