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
Abstract:
A t the present time, there ex ist two k inds o f designs for imp lemen ting Anycast serv ice: one is bu ilt on IP layer, the other on application layer, but they are both confron ted w ith some problem s, such as sca lability. To so lve the ex isting problems a new k ind ofAnycast commun icationmodel is proposed in this paper. This Anycast communicationmode l ut ilizes DNS layered domain name techno logy and adopts TRT and RTT of netw ork serv ice provided byAnycast servers as the measure units. Th is communicationmode l not only solves Anycast sca lab ility but also a llow s Anycast members to freely leave and jo in Anycast group. In addition, th ismodel a lso accomplishes the distributed ma intenance and transaction o fAnycastmembers. informat ion to achieve the load balance and it is ab le to support the large-sca leAnycast group. The experimental data of implement ing th is model in IPv6 emulat ion env ironm ent argue that th is model is feasib le and efficient.
