| 摘 要： | 针对移动组播中存在的家乡代理单点失效问题，提出一种多家乡代理实现机制，解决多家乡代理中移动节点的家乡注册问题，引入新的应用层任播算法，可以从多个家乡代理中为移动组播接收者选择“最近”的家乡代理。分析结果表明，该任播算法不仅可以有效解决家乡代理单点失效问题，还能为移动节点提供高质量的任播解析服务。

| Abstract: | Aiming at the failed single point problem for Home Agents(HAs) in mobile multicast, an implementation mechanism of Multiple Home Agents for Mobile Multicast(MHAsMoM) is proposed. The problem of home registration among multiple HAs is solved. Meanwhile, a novel application-layer anycast algorithm is adopted in the scheme, which can choose the “nearest” HA from multiple HAs in the home network for mobile multicast receivers. Analysis results show MHAsMoM can not only solve the problem due to HA as a central point of failure, but also provide better anycast resolution service. |
