一种基于服务质量的启发式点对点多媒体通信路由选择算法
A QoS-Based Heuristic Pomt-to-Point Multimedia Communication Routing Algorithm
【摘要】 <正> 1 引言分布式多媒体应用通常有比较严格的QoS需求。通常,如果网络要向分布式多媒体应用提供QoS保证,就应该进行接纳控制并且作出资源预约。但是,接纳测试和资源预约依赖于路由,仅当路由选择算法找到有足够资源满足应用需求的路径时,才能作出资源预约,也才能确定能否提供先验QoS保证。因此,路由选择算法需要考虑应用的QoS需求,同时,从尽可能多地容纳分布式多媒体应用用户的角度出发,在进行路由选择时还应考虑QoS计费。研究基于QoS的网络路由选择机制既有理论意义也有应用价值。
【Abstract】 QoS(Quality of Service)based network routing mechanisms are fundamental means which can provide QoS guarantees required by distributed multimedia applications. In this paper,a QoS based heuristic routing algorithm for point-to-point multimedia communication routing mechanisms is presented and discussed in detail.
