【摘要】 针对网络中不同优先级数据流对QoS的不同需求提出一种新的基于半动态网络资源分配策略,并且根据每类流分得的资源以及各类流在该时刻内链路中剩余的资源实施路由选择策略。实验结果表明,与其它两种基于资源分配的QoS策略相比,该算法能够兼顾公平,又能满足不同类流对网络资源的需求。更多还原

【Abstract】 According to the various QoS requirements of different PRI data stream in Internet, a new strategy for semi-dynamic resource allocation (SDRA ) is proposed. The path-selection is decided based on the amount resource each class shared and the residual resource in the path simultaneously. It has been proved that compared with the other tow QoS strategies this method can meet different requirements of Internet resource for all kinds of data streams.更多还原
