| 摘 要： | 针对任播(Anycast)的扩展局限性问题,在IPv6模拟环境下,扩展了原有IPv6中的Anycast概念,提出了一个IPv6中的k-Anycast通信模型,该模型允许k个服务器协同工作共同完成一项服务,实现了k-Anycast 对象动态加入和离开,并且不受物理位置的限制.此外,在该模型中k-Anycast服务请求消息会被距离最近的k-Anycast 对象处理,这样使得k-Anycast服务请求均衡地分布在k-Anycast 对象之间从而得到高效处理.在IPv6模拟环境下,将k-Anycast模型应用到内容分发网络技术中,实验数据证明:k-Anycast模型的应用不仅大幅度提高了服务质量,而且有效节省了网络带宽.

| Abstract: | In an IPv6 simulation environment,this paper extends the original Anycast concept and proposes the concept of k-Anycast communication model in IPv6 which allows k servers to cooperate with each other to accomplish a task to solve the Anycast existing scalability problem.This model can achieve dynamic join and leave of k-Anycast object without restrictions of physical location.In addition,this model can route k-Anycast service request messages to the nearest k-Anycast object that can provide the requested se... |
