摘要：
PROBLEM TO BE SOLVED: To transparently change over a server desired by a client by dynamically selecting it without needing a management server or without imposing a processing load for specifying the server on a client terminal when selecting and accessing a plurality of servers. SOLUTION: Servers 3a-3n are composed by installing totally identical IPv6 anycast address and multicast address, and access from a terminal 1 uses the anycast address. When it is determined for a request file from the terminal 1 that the file cannot be provided, the servers 3a-3n transmit the file request content to other servers by using the multicast address, and annunciate the unicast address of the server having first received the feasibility of provision to the terminal 1 as routing information. After receiving the routing information, the terminal 1 transmits a message to the anycast address by attaching an IPv6 expansion header using the received anycast address for routing information.

摘要（中）：
要解决的问题：通过在不需要管理服务器的情况下动态地选择客户端所需的服务器，或者在选择和访问多个服务器时不在客户终端上指定服务器时施加处理负载来透明地切换服务器。 解决方案：服务器3a-3n由安装完全相同的IPv6任播地址和组播地址组成，终端1的访问使用任播地址。 当确定来自终端1的请求文件不能提供文件时，服务器3a-3n通过使用多播地址将文件请求内容发送到其他服务器，并且通知首先接收到的多播地址的服务器的单播地址 提供给终端1作为路由信息的可行性。 终端1在接收到路由信息后，通过使用接收的路由信息的任播地址附加IPv6扩展报头，向任播地址发送消息。 版权所有（C）2007，JPO＆INPIT
