用于采用负载均衡的移动通信的方法和装置
摘要：
一种用于利用负载均衡的移动通信的方法和装置。当一个本地代理(HA)是由一个或多个服务器组成时，其中每个服务器被分配一个移动IPv6本地代理任播地址时，一个附近的路由器在其邻居高速缓冲存储器中相对于该服务器的任播地址不存储该链路层地址。因此，在这些服务器之间无法实施负载均衡。为了解决这个问题，在一个示例中，提供了一个包括典型HA和分布式HA的HA。该典型HA被分配一个任播地址。该典型HA包括一个采集装置，配置成从该分布式HA采集HA目录和负载信息。该典型HA动态地生成一个HA目录，并且发送该HA目录给一个移动节点(MN)。该MN向包括在本地代理地址发现应答消息中的该HA目录中的一个HA登记其当前位置。因而在该HA上的负荷可以由组成该HA的服务器共享。
摘要（英）：

A method and apparatus are provided for mobile communication utilizing load balancing. When a home agent (HA) consists of one or more servers with each server being assigned a Mobile IPv6 Home-AgentsAnycast Address, a nearby router does not store the link-layer addresses with respect to the Anycast addresses of the servers in its neighbor cache. Consequently, load balancing between or among the servers could not be performed. To solve this problem, in one example, an HA is provided that comprises a representative HA and distributed HAs. The representative HA is assigned an Anycast Address. The representative HA includes a collecting device configured to collect HA lists and load information from the distributed HAs. The representative HA dynamically creates a HA list and sends the HA listto a mobile node (MN). The MN registers its current location with an HA from the HA list included in a Home Agent Address Discovery Reply message. The load on the HA can then be shared by the serversconstituting the HA.
