Abstract: Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address, which may be allocated by the Foreign Agent. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes or to a cluster of Mobile Nodes (e.g., associated with the care-of address) via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded directly to one of the Mobile Nodes assigned that Home Address. Alternatively, when an address such as the care-of address is associated with multiple Mobile Nodes, the Foreign Agent may perform a second level of dispatching such that the server request is dispatched to one of the Mobile Nodes in the cluster.

Abstract translation: 公开了由支持移动IP的归属代理处理注册请求的方法和装置。 从多个移动节点中的每一个接收注册请求，该注册请求指定可由外地代理分配的转交地址。 在多个移动节点中的每个移动节点和相关的转交地址之间建立绑定，多个移动节点中的每一个彼此相关联。 例如，多个移动节点可以静态地或动态地分配相同的归属地址。 然后在归属代理和多个移动节点中的每一个的转交地址之间创建隧道，从而使得归属代理能够将服务器请求分发到多个移动节点之一或者移动的群集 节点（例如，与转交地址相关联）通过相关联的隧道。 例如，寻址到归属地址的服务器请求可以直接转发到分配给归属地址的移动节点之一。 或者，当诸如转交地址的地址与多个移动节点相关联时，外部代理可以执行第二级调度，使得服务器请求被分派到群集中的移动节点之一。
