The algorithm applies on-demand procedures to dynamically refresh routes and build multicast forwarding group.
算法采用按需路由发现过程，动态更新路由信息和建立多播转发组。
Aiming at distributed router, we design the optimized distributed storage of multicast forwarding table, and two level forwarding project for multicast datagram.
针对分布式路由器，设计了组播转发表优化分布式存储及组播报文两级转发方案提高性能。
In traditional IP multicast, data for a given group is forwarded through a tree structure covering the members of this group. The on-tree routers must maintain a per-group forwarding state.
在传统组播中，组播组数据由一棵覆盖所有组成员的组播树进行转发，树上路由器必须保存每一个组播组的转发状态。
With multicast tree aggregation, fewer trees are maintained which amounts to reduce both the number of forwarding states in routers and the overhead induced by control messages.
组播组的聚合使得网络中组播树的数量减少，路由器需要维持的组播转发状态和传递控制信息带来的控制开销都大大降低。
The multicast tree switching method and the device realize optimum forwarding path for multicast tree switching.
应用本发明提供的方法和装置使组播树切换时转发路径最优。
In response to this problem, this paper designs a layer2 forwarding method to handle the multicast traffic.
针对这一问题，本文设计了一个组播流的二层转发管理方案。
Since multicast may have many receivers, for effective transmission, the router needs a tree to join multiple IP members, with Multicast RIP and its data packet forwarding function.
多点广播的接收方可能很多，为了有效地进行传输，路由器要构造一个连接IP多点广播组所有成员的树，采用多点广播路由选择协议并启用多点广播数据包转发功能。
And a forwarding table for multicast traffic should be built according to the changes of the forwarding state.
根据转发状态的变化情况，构建出组播数据的二层转发表。
When there are large Numbers of multicast groups in the network, large forwarding tables induce large memory requirements and slow down the address look-up process.
当大量组播组并存于网络时，数量庞大的转发状态表占用了大量内存资源并且减缓了组播地址查询过程。
The simulation result has shown that ODCMRP have more excellent performance than basic ODMRP on the aspects of packet overhead and forwarding efficiency when the size of multicast group grows up.
仿真结果表明，相对ODMRP协议，基于簇的按需组播路由协议ODCMRP可以更有效地减少数据负载和控制开销，因而能更好地适应组播规模的扩展需要。
Using camouflage multicast address and multi-proxy forwarding technology, the new protocol improves the anonymity of sender and receiver, which can defend compromised proxy.
MACP通过引入伪装组和多代理转发机制，提高了协议的匿名性能，保证了在代理服务器被攻占的情况下，匿名性能不会被破坏。
