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.

摘要： Techniques are provided to enable support of roaming wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam across mobility sub-domains. Traffic for a wireless device that roams is tunneled back to the access switch that serves the IP subnet which includes an IP address for the wireless device. Traffic is tunneled back to that access switch for the wireless device when the wireless device roams to another access switch which does not serve the IP subnet for the wireless device in the same mobility sub-domain and when the wireless device roams to a different mobility sub-domain, in which case the traffic is tunneled between tunneling endpoints in the respective mobility sub-domains.

摘要： Techniques are provided to support roaming of wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam within and across mobility sub-domains. When a wireless device roams from one access switch to another access switch, a tunneling endpoint apparatus in the wireless device's home mobility sub-domain is configured to serve as the point of presence for the roamed wireless device. Traffic for the roamed wireless device is tunneled from the access switch where the wireless device has roamed (where it is currently attached) to the tunneling endpoint apparatus. When the wireless device roams across mobility sub-domains, then traffic is tunneled from the access switch where the wireless device is currently attached to the tunneling endpoint apparatus in that mobility sub-domain (called a “foreign” mobility sub-domain) to the tunneling endpoint apparatus in the wireless device's home mobility sub-domain.

摘要： Methods and apparatus for registering a mobile device such as a mobile node or mobile router with a Home Agent in an asymmetric link environment. A Foreign Agent associates each of one or more interfaces of the Foreign Agent with a different care-of address. An agent advertisement including the care-of address for the one or more interfaces of the Foreign Agent is then sent via one or more uplinks. A registration request is received via a downlink router. The registration request identifies a care-of address associated with one of the one or more interfaces of the Foreign Agent. One of the interfaces identified by the care-of address is ascertained, thereby identifying the interface to which the mobile device has roamed. The registration request is forwarded to the Home Agent. A registration reply is received from the Home Agent. The registration reply is then forwarded to the mobile device via the ascertained interface.

摘要： In one embodiment, accounting information for a mobile node operating according to Mobile IP Protocol is updated. A network device that supports Mobile IP composes a request packet for the mobile node. The request packet identifies the mobile node and includes at least one counter associated with accounting information pertaining to the mobile node. The request packet is then sent to a server adapted for performing accounting. The server then logs the accounting information for the mobile node. The server may then send a reply packet to the network device acknowledging logging of the accounting information pertaining to the mobile node. A bill for Mobile IP services may then be generated from the accounting information.

Specifically, a Mobile-Foreign authentication key is separately generated by both the Mobile Node and Foreign Agent. Similarly, a Foreign-Home authentication key is separately generated by the Foreign Agent and the Home Agent. In accordance with one embodiment, generation of the Mobile-Foreign authentication key and Foreign-Home authentication key are accomplished via the Diffie-Hellman key generation scheme.
