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: Methods and apparatus for registering with a Home Agent are disclosed. The network device sends a registration request having a home address field including an IP address to a Home Agent associated with the IP address. The IP address may be an IP address that has been statically assigned to the network device or an IP address that is a personal IP address that is associated with the user (e.g., username or NAI). The registration request indicating one or more ports of the network device via which data packets or server requests addressed to the IP address are to be received. The ports may be specified in a port extension to the registration request. In addition, the registration request may indicate a priority to be associated with the registration. The Home Agent updates its mobility binding table with the IP address and care-of address, as well as other information specified in the registration request, such as port and/or priority information. The Home Agent then sends a registration reply to the network device. When the registration request is not sent directly by the network device (e.g., via a collocated care-of address), the Foreign Agent updates its visitor table upon receipt of the registration reply with the Home Agent address and IP address, as well as port and/or priority information. The registration reply is then sent to the network device. In this manner, multiple registrations for a single device or user may be established according to specified port(s). These registrations may further be prioritized to enable various applications and/or devices to be prioritized.

Abstract translation: 公开了向归属代理登记的方法和装置。 网络设备向与IP地址相关联的归属代理发送具有包括IP地址的归属地址字段的注册请求。 IP地址可以是静态地分配给网络设备的IP地址或作为与用户相关联的个人IP地址的IP地址（例如用户名或NAI）。 指示要接收到寻址到IP地址的数据分组或服务器请求的网络设备的一个或多个端口的注册请求。 端口可以​​在注册请求的端口扩展中指定。 此外，注册请求可以指示与注册相关联的优先级。 归属代理使用IP地址和转交地址以及注册请求中指定的其他信息（例如端口和/或优先级信息）来更新其移动性绑定表。 归属代理然后向网络设备发送注册回复。 当注册请求不是由网络设备直接发送（例如，通过并置的转交地址）时，外部代理在接收到归属代理地址和IP地址以及端口的注册回复后更新其访问者表 和/或优先级信息。 然后将注册答复发送到网络设备。 以这种方式，可以根据指定的端口建立单个设备或用户的多个注册。 可以进一步优先考虑这些注册，以使各种应用和/或设备被优先化。
