IPv6任播及其安全性分析

Analysis of Anycast and its Security Issues over IPv6 Network

任播作为一种网络服务模式越来越受到关注,原因是它能够选择对于客户来说最优的一个(最好是一个)服务器。对任播技术的最初研究集中在网络层,在网络层路由器自动完成选路,而应用层任播通过客户的参与带来了更多的灵活性。本文分别对两种任播技术进行了论述,重点介绍如何在应用层找到最优服务器,并对任播的安全性问题进行了分析。

Anycast is a communication model for IP. It becomes more and more popular as it can be used to select a server （preferably only one） who can provide the best service for client. At the beginning, the main research of anycast is in IP Layer. It can complete routing automatically in IP Layer; however, anycast can bring more flexibility in application layer with the participation of client. In this paper, we discuss the implementation of anycast in these two layers, and put stress on how to implement anycast in application layer to select the best server, and we also analyze security issues of anycast.
