摘要： In one embodiment, a received data packet is delivered by a routing resource to a tunnel interface resource in response to determining that the received data packet specifies a destination address starting with a prescribed aggregation prefix. The tunnel interface resource computes a home address for a mobile router based on a second address prefix from a start of the destination address, the second address prefix within the prescribed aggregation prefix and having been assigned as reachable by the mobile router, at least a portion of the second address prefix applied to a prescribed mapping function. The tunnel interface resource determines a care-of address for reaching the mobile router based on the corresponding home address calculated by the tunnel interface resource, and encapsulates the received data packet into an encapsulated packet having a destination address field specifying the care-of address, for output of the encapsulated packet toward the mobile router.

摘要： The present disclosure generally provides techniques for establishing a unique, ephemeral home address (hoa)/home agent address (ha′) address pair that may be limited to use in a session having a defined lifetime. Limiting the use of this dynamic address pair to a session lifetime and by preventing a mobile node from knowing the static address of a home agent may help protect the home agent from attacks.

摘要： Methods and apparatus for performing optimizations for a mobile network device such as a Mobile Node or Mobile Router supporting multiple links to a Home Agent (or Correspondent Node in a Mobile IPv6 environment) are disclosed. During the registration process, link characteristics are transmitted in the registration request. From the link characteristics, it is possible to determine whether the mobile network device has roamed from a high to a low bandwidth link, or vice versa. A first set of optimizations may be performed when the mobile network device has roamed from a high to a low bandwidth link, while a second set of optimizations may be performed when the mobile network device has roamed from a low to a high bandwidth link. Some optimizations may be performed during the establishment of a TCP session, while others may be performed during or upon completion of the Mobile IP registration process.

摘要： Methods and apparatus for enabling VPN based mobility are provided. A VPN client having a client subnetwork address corresponding to a particular subnetwork can create a VPN tunnel using an enterprise address from a VPN server. Using the VPN tunnel, the VPN client can establish sessions with a variety of destination nodes including destination nodes on a private or enterprise network associated with the VPN server. When the client moves, the VPN client can acquire a new address that may correspond to a new subnetwork, but the VPN server provides the VPN client with the same enterprise address. Accordingly, the VPN client can maintain existing sessions with destination nodes using the same enterprise address.
