摘要
针对嵌入式系统的资源有限性问题,结合网络数据的特点,提出了一种能够有效支持服务质量(qualityof service,QoS)策略的缓冲区管理方法.该方法可高效支持多业务流操作,并且实现了数据在网络设备上的零拷贝.在基于自主开发的高清晰度电视(high definition television,HDTV)双向系统平台上进行仿真测试,结果证明本文中的缓存区管理方法可以有效提高电缆调制解调器(cable modem,CM)转发数据的能力.
This paper brings forth a scheme of efficient buffer management, which can support QoS strategies effectively. This management takes account of the feature of data in the networks and the source-constrain of the embedded system. It can support multi-service flow operations, and realizes the data zero-copy technology. After simulation tests on our independent R＆D bidirectional platform for HDTV, we find that this scheme can promote the data transmission ability of CM.
