Improving the Upstream Bandwidth Allocation Policy for the HFC Broadband Access Networks
HFC宽带接入网上行带宽分配策略的改进

The request/transmit based upstream bandwidth resource allocation policy of DOCSIS introduces a trouble to the quality of the data service provided in the HFC networks. In this paper, the mechanism of the upstream data transmitting and the process of data service transmitting in the HFC networks are described in detail, and the performance of the data service in HFC networks is analyzed. An advanced upstream bandwidth resource allocation policy is proposed to improve the quality of the data service in the HFC networks.
