Scheme for buffer management based on QoS

As broadband network services are becoming more and more abounding, the QoS(quality of service) of broadband networks has caught the attention of many professional people. Sometimes, the resource-constrain of embedded systems affects the quality of the multimedia services seriously. To solve this problem, this paper proposes an effective scheme for buffer management, which is named QoSBuf.. This scheme takes the feature of data in the networks into account and uses the buffer space rationally. It also can support multi-service flow operations and realize the data zero-copy technology. Through some simulation tests on our independent R&D bidirectional platform for HDTV, we find that this scheme can promote the data transport ability of the CM (Cable Modem).
