摘要： Methods and apparatus for dynamically generating authentication keys are disclosed. 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.

摘要： In one embodiment, a method includes receiving, at a visited network node, policy for a roaming terminal from a home network of the roaming terminal. The policy is associated with a home Internet Protocol (IP) address of the roaming terminal. The visited network node applies the policy in the visited network to data packets that include the home IP address. Applying the policy to a data packet encompasses either enforcing the policy at the node that applies the policy or sending data that indicates the policy to a different node that applies the policy based on the data sent, or both.

摘要： Communicating packets along a bearer path includes receiving a home network address and a visited network address at an access terminal. The home network address corresponds to a home anchored bearer path anchored at a home network of the access terminal. The visited network address corresponds to a visited anchored bearer path anchored at a visited network. The access terminal determines whether to use the home anchored bearer path or the visited anchored bearer path, and communicates packets using the home network address or the visited network address in accordance with the determination.

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 preventing an IP address from being assigned to a client implementing a protocol such as DHCP are disclosed. This is particularly useful in an environment such as a Mobile IP environment in which a network device (e.g., Access Point) performs proxy registration on behalf of the client. When the client transmits a detection packet to detect whether its IP address is still valid (e.g., whether it is on the same sub-network on which the IP address was allocated), a response is transmitted to the client that indicates that the client is still on its home network. This response is transmitted regardless of whether the client is still on its home network. Since the client believes it is still on its home network, a new IP address will not be assigned to the client. As a result, an existing Mobile IP session will not be interrupted.

摘要翻译： 公开了防止IP地址被分配给实现诸如DHCP之类的协议的客户端的方法和装置。 这在诸如移动IP环境的环境中特别有用，其中网络设备（例如，接入点）代表客户机执行代理注册。 当客户端发送检测分组以检测其IP地址是否仍然有效（例如，是否在分配了IP地址的同一子网上）时，会向客户端发送一个响应，指示客户端 仍然在其家庭网络。 无论客户端是否仍在其家庭网络上，都会发送此响应。 由于客户端认为它仍然在其家庭网络上，因此不会将新的IP地址分配给客户端。 因此，现有的移动IP会话将不会中断。

摘要： An optical cross-connect switch employing pallets of mirror assemblies configured as an array, wherein each mirror assembly includes a mirror that is rotatable in a two-axis system to steer a beam in 2-dimensional space. Each mirror assembly includes a mirror module that can be rotated in relation to a first axis as well as in relation to a second axis that is perpendicular to the first axis. The mirror modules are suspended by wires in a manner that allows the pitch and roll of the mirror module to be controlled. Coils and magnets are employed to generate magnetic fields which create a rotating torque in each of the two rotational axes. By controlling the magnetic fields that are generated, the degree of rotation can in turn be controlled. The configuration provides for a practical, area efficient, bidirectional, randomly addressable optical cross-connect switch design that can employ conventional materials and processes.
