| 摘 要： | 为解决IPv6提供任播(Anycast)服务时存在的扩展性等问题,该文提出了一种新的Anycast通信模型,该模型采用DNS域名分层技术以及以Anycast组成员提供网络服务的TRT以及RTT等参数做为度量单位的Anycast通讯方式,不仅解决了Anycast的扩展局限性问题,同时也实现了Anycast组成员的动态加入与注销,以及Anycast组成员信息的分布式维护与处理,从而实现了均衡负载功能,最重要的是此模型可以支持大规模的Anycast组的建设.该模型在IPv6模拟环境下的实验数据充分论证了其可行性以及有效性.

| Abstract: | At the present time,there exist two kinds of designs for implementing Anycast service: one is built on IP layer,the other on application layer,but they are both confronted with some problems,such as scalability.To solve the existing problems a new kind of Anycast communication model is proposed in this paper.This Anycast communication model utilizes DNS layered domain name technology and adopts TRT and RTT of network service provided by Anycast servers as the measure units.This communication model not only solves Anycast scalability but also allows Anycast members to freely leave and join Anycast group.In addition,this model also accomplishes the distributed maintenance and transaction of Anycast members' information to achieve the load balance and it is able to support the large-scale Anycast group.The experimental data of implementing this model in IPv6 emulation environment argue that this model is feasible and efficient. |
