摘要： Methods and apparatus for optimizing Mobile VPN communications are disclosed. When a data packet is transmitted between a Mobile Node that is a member of a VPN and a Correspondent Node, the data packet is transmitted between the Mobile Node and a Home Agent via a Mobile IP tunnel without transmitting the data packet via a VPN tunnel. However, the data packet is transmitted between the Home Agent and a VPN headend via a VPN tunnel.

摘要： The present invention provides methods and apparatus for managing an IP address assigned to a Mobile Node. In one embodiment, the Mobile Node appends an extension to the registration request that is sent to its Home Agent, which indicates that the Mobile Node requests use of the IP address previously assigned to the Mobile Node for an additional period of time. When the Home Agent receives the registration request, it indicates whether a lease on the IP address previously assigned to the Mobile Node has been granted by the Home Agent for an additional period of time. In another embodiment, the Home Agent sends a first control message to determine whether the Mobile Node continues to use the IP address. The Home Agent then determines whether a second control message has been received in order to ascertain whether the Mobile Node continues to use the IP address previously assigned to the Mobile Node. The present invention is preferably performed when a Mobile Node returns to its home network, thereby enabling the Mobile Node to retain the IP address assigned to it.
摘要翻译：本发明提供了用于管理分配给移动节点的IP地址的方法和装置。在一个实施例中，移动节点将附加到发送到其归属代理的注册请求的扩展，其指示移动节点请求使用先前分配给移动节点的IP地址一段时间。当归属代理接收到注册请求时，它指示先前分配给移动节点的IP地址上的租约是否已由归属代理许可一段时间。在另一个实施例中，归属代理发送第一控制消息以确定移动节点是否继续使用IP地址。归属代理然后确定是否已经接收到第二控制消息以便确定移动节点是否继续使用先前分配给移动节点的IP地址。本发明优选地在移动节点返回到其归属网络时进行，从而使得移动节点能够保留分配给它的IP地址。

摘要： Methods and apparatus for dynamically generating a set of Mobile IP keys are disclosed. The set of Mobile IP keys is dynamically generated using an existing HLR/AuC authentication infrastructure. This is accomplished, in part, by obtaining an International Mobile Subscriber Identity (IMSI) that uniquely identifies a particular Mobile Node. Once a set of Mobile IP keys is generated from authentication information associated with the IMSI, the Mobile Node may register with its Home Agent using the set of Mobile IP keys.

摘要： Methods and apparatus for performing proxy registration on behalf of a node with a Home Agent supporting Mobile IP are disclosed. A first registration request is composed on behalf of the node and transmitted to the Home Agent via a first Local Mobility Anchor, wherein the first Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with the first Local Mobility Anchor. When the node moves within a region or between regions, the node is re-registered. Specifically, a second registration request is composed and transmitted to the first Local Mobility Anchor when the node moves within the region associated with the first Local Mobility Anchor. When the node moves into a second region associated with a second Local Mobility Anchor and outside the first region associated with the first Local Mobility Anchor, a second registration request is composed and transmitted to the Home Agent via the second Local Mobility Anchor, wherein the second Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with second first Local Mobility Anchor.

摘要： Methods and apparatuses for obtaining home agent assignment. The invention uses a DNS query to signal a request for dynamic home agent assignment. The DNS query will cause a content routing device to be notified that home agent assignment is being requested. The content routing device can then use predetermined metrics to select a home agent. A DNS response will then be sent back to the device that initiated the DNS query containing the IP address of the selected home agent.

摘要： A data processing apparatus comprises instructions to perform sending and receiving one or more messages conforming to a network routing protocol, such as Open Shortest Path First (OSPF); obtaining one or more information elements that specify one or more capabilities of the apparatus; creating a particular routing protocol message comprising an opaque advertisement that includes the one or more information elements; and sending the particular message on one of the network interfaces. For example, a router or switch that implements a network routing protocol can use OSPF Opaque Link State Advertisements to advertise and discover services and capabilities of other routers or switches.

摘要： An adaptive feedback technique is described for a Mobile IP environment in which Mobile IP mechanisms provide early feedback to mechanisms in the transport layer and/or application layer of a mobile node in response to detection of changes in link characteristics of the communication used by the mobile node to communicate with a data network. Using the early feedback information, appropriate measures may then be taken in order to accommodate the changes in link characteristics. Such appropriate measures may include, for example, providing feedback to media aware applications in order to allow such applications to dynamically adjust their bandwidth requirements to accommodate the new link characteristics, modifying timeout parameters, modifying an encoding formats to accommodate the new link characteristics, notifying participants in a real-time application session of the detected changes in the link characteristics, etc.

摘要： In accordance with one aspect of the invention, methods and apparatus for distributing a Mobile IP registration request to one of a plurality of Home Agents are disclosed. A registration request is received from a Foreign Agent to which the Mobile Node has roamed. One of the plurality of Home Agents is selected. The registration request is then forwarded to the selected one of the plurality of Home Agents. The source IP address of the registration request is an IP address of the Foreign Agent to which the Mobile Node has roamed, thereby enabling the selected one of the plurality of Home Agents to send a Mobile IP registration reply directly to the Foreign Agent without interception by the network device.
