【摘要】 随着网络技术以及商业化应用的飞速发展,带QoS约束的多播路由成为必要.在QoS多播路由中,很难取得管理费用、加入延迟和加入成功率以及多播树性能之间的平衡.提出了一种查询式的单路径/多路径自适应多播路由协议,能够在较低费用的情况下保证节点加入多播树的成功率.模拟结果表明,该协议能够很好地同时适应组成员稀疏或密集的情况.更多还原

【Abstract】 With the rapid development of network technology and its commercial implementation,the multicast routing with quality of service(QoS) constraint is highly required.However for QoS multicast routing,it is difficult to reach compromise over manage overhead,delay,success rate,performance of multicast tree.A query-based single/multiple-path auto-adapted multicast routing protocol is proposed.It guarantees the success rate of a node joining a multicast tree with low overhead.The simulation suggests that this protocol works well in both sparse and dense mode.更多还原
