摘要： Methods and apparatus for implementing proxy Mobile IP in a system implementing multiple VLANs are disclosed. Specifically, a network device such as an Access Point or Foreign Agent supports multiple VLANs on a plurality of interfaces. In addition, the network device implements proxy Mobile IP on at least one interface. The network device ascertains a subnet map of a node, where the subnet map corresponds to a VLAN. It then identifies a Home Agent associated with the subnet map or VLAN via which to register the node. The network device then composes a registration request on behalf of the node, where the registration request identifies the node (e.g., IP address) and includes a Home Agent address associated with the Home Agent. The registration request also directly or indirectly indicates the interface corresponding to the VLAN via which data packets are to be routed. The registration request is then sent on behalf of the node. A registration reply that indicates success or failure of the proxy registration performed on behalf of the node is then received. Upon successful proxy registration, data packets may be transmitted on the VLAN interface of the network device.

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 apparatus for providing a centralized source of session keys to be shared by a Home Agent and a Mobile Node are disclosed. In accordance with one aspect of the invention, a Mobile Node registers with a Home Agent supporting Mobile IP by sending a registration request to the Home Agent. The Home Agent sends a request message (e.g., access-request message) to a AAA server, the request message identifying the Mobile Node. The AAA server then derives key information from a key or password associated with the Mobile Node. The AAA server then sends a reply message (e.g., access-reply message) to the Home Agent, the reply message including the key information associated with the Mobile Node, thereby enabling the Home Agent to derive a shared key to be shared between the Mobile Node and the Home Agent from the key information. The Home Agent derives a key from the key information, the key being a shared key between the Mobile Node and the Home Agent. A registration reply is then sent to the Mobile Node. When the Mobile Node receives a registration reply from the Home Agent, the registration reply indicates that the Mobile Node is to derive a key to be shared between the Mobile Node and the Home Agent. The Mobile Node then derives a key to be shared between the Mobile Node and the Home Agent from key information stored at the Mobile Node. The Mobile Node may initiate “re-keying” by sending a subsequent registration request to the Home Agent.

摘要： Methods and apparatus for establishing an optimized route between a node and a Correspondent Node are disclosed. In a Mobile Router supporting Mobile IP, the Mobile Router having one or more networks associated therewith, a method of establishing a route between one or more nodes associated with one of the networks of the Mobile Router and a Correspondent Node includes composing a HOTI message on behalf of at least one of the nodes, which is sent from the Mobile Router to a Correspondent Node via a Home Agent supporting the Mobile Router. The Mobile Router sends a COTI message to the Correspondent Node on behalf of the node. The Mobile Router receives a HOT message from the Correspondent Node. It then receives a COT message from the Correspondent Node, thereby enabling a binding between the node(s) and the Correspondent Node to be generated such that data packets transmitted between the node(s) and the Correspondent Node can be routed between the node(s) and the Correspondent Node without being routed via the Home Agent.

摘要： Methods and apparatus for enabling a Mobile Node supporting mobile IP to roam without an assigned IP address and receive lookups indicating that a Corresponding Node wants to send information to the Mobile Node are disclosed. A name lookup may be sent from a Corresponding Node to a Home Agent that has previously registered the Mobile Node. The name lookup may be sent through an intermediate device, including a Domain Name Server, such that the intermediate device contacts the Home Agent. During the name lookup process, an IP address is allocated to the Mobile Node and a data path is established between the Home Agent and the Mobile Node via a Foreign Agent. When the lookup is completed successfully, the Home Agent sends the IP address allocated to the Mobile Node in the name lookup process to the device requesting the lookup. The IP address of the Mobile Node may then be used by the Corresponding Node to “push” information to the Mobile Node.

摘要： Methods and apparatus for establishing an optimized route between a Mobile Node and a Correspondent Node are disclosed. In particular, a Correspondent Node is notified of the location of a Mobile Node, thereby enabling the Correspondent Node to communicate directly with the Mobile Node. This is accomplished by sending a HOTi message protected in IPSec transport mode from the Mobile Node to a Home Agent associated with the Mobile Node for modification and transmission of a modified HOTi message to the Correspondent Node. The Mobile Node then receives a HOT message protected in IPSec transport mode from the Home Agent associated with the Mobile Node, the HOT message being received from the Home Agent associated with the Mobile Node after modification has been performed by the Home Agent on an initial HOT message received by the Home Agent from the Correspondent Node.

摘要： Techniques are provided for seamless integration of wired and wireless functionality packet forwarding in network. A plurality of access switches are provided in each of a plurality of mobility sub-domains that are part of a mobility domain of a network. Each access switch serves one or more Internet Protocol (IP) subnets, each comprising a plurality of IP addresses. An access switch obtains an IP address for a wireless device according to the one or more IP subnets that the access switch serves. The access switch sends an association advertisement message to indicate the IP address of the wireless device and to enable other access switches and routers to compute a path to the wireless device. When a wireless device obtains an IP address, it can keep the same IP address as it roams in the mobility domain.
