Abstract

In this paper we have proposed HRSQM, Heterogeneous Receivers Supporting QoS Multicast, which is a distributed protocol that creates multicast tree for receivers with heterogeneous QoS requirements. It relies only on local states and does not use any global state. Furthermore, through exhaustive search and carefully selecting branch to connect the new node to the tree, the efficiency of tree is always near optimal. Also it reshapes the multicast tree to improve resource utilization. Thanks to the current high-speed networks, HRSQM combines resource reservation with routing. By comparing it with other related protocols through simulations, we find that it has higher success ratio, also the resulting multicast trees of HRSQM require much fewer links than other methods.
HRSQM:支持QoS组播的异构接收器
本文提出了一种为具有异构QoS需求的接收方创建组播树的分布式协议——异构接收方支持QoS组播。它只依赖于局部状态,不使用任何全局状态。此外,通过穷举搜索和仔细选择分支将新节点连接到树中,使树的效率始终接近最优。此外,它还对组播树进行了重构,以提高资源利用率。由于目前的高速网络,HRSQM结合了资源预留和路由。通过与其他相关协议的仿真比较,我们发现HRSQM具有更高的成功率,并且得到的组播树所需的链路也比其他方法少得多。
