| 摘 要： | 提出了一个基于Nat-Pt和scatter cast的IPv4与IPv6组播的过渡方案.该方案利用scattercast组播体系基于proxy实现的特性,将IPv4的应用层组播和IPv6的IP组播结合在一起,形成一个完整的组播过渡体系.通过在Nat-Pt的两侧设置关键SCX节点,限制了通过Nat-Pt建立的组播通道数量.为提高组播网络的鲁棒性,引入多Nat-Pt协同的连接方式,并设计了多Nat-Pt控制算法.仿真实验结果表明,该组播方案能够实现IPv4向IPv6的平滑过渡,并比单纯的应用层组播有更高的效率,同时网络具有良好的鲁棒性.

| Abstract: | A transition multicast scheme on application layer for IPv4 and IPv6 based on Nat-Pt and scatter cast is presented,which integrates the IPv4 application-level multicast and IPv6 IP layer multicast into an integrated transition multicast scheme.There are critical scatter cast proxies on both sides of the NatPt in this scheme,which will restrict multicast connection numbers.The cooperation scheme and control algorithm in multiple Nat-Pts strengthen the reliability and robustness of the transition multicast network.The simulation results show that this scheme can accomplish a smooth transition from IPv4 to IPv6 with better effectiveness and robustness. |
