Abstract
Hybrid fiber coaxial (HFC) network has recently emerged as a promising access network infrastructure for the delivery of voice, video and high-speed data traffic. This paper first described the activity of cable modem termination system (CMTS) and cable modem (CM). Then the effect of the upstream bandwidth resource allocation mechanism based on request/transmit policy on the performance of asymmetric data application is analyzed. An active grant upstream bandwidth allocation policy is proposed to improve the performance of asymmetric data application over the HFC networks. The simulation result is also given.
