  • Allowing network access for proxy mobile IP cases for nodes that do not support CHAP authentication
    Patent number: 8042154
    Abstract: The disclosed embodiments support proxy Mobile IP registration for nodes that do not implement CHAP. This is accomplished, in part, through the generation of a CHAP challenge and response by either a AAA server or a network device such as a PDSN or Foreign Agent. If the CHAP challenge and response is generated by the AAA server, the AAA server provides the CHAP challenge and response to the network device. In this manner, the network device may generate a Mobile IP registration request based upon the CHAP challenge and response.

  • Method to dynamically provide link specific information to mobile clients
    Patent number: 8036184
    Abstract: The disclosed embodiments enable a Mobile Node to select from or prioritize two or more Foreign Agents using information dynamically provided to the Mobile Node. When a Foreign Agent detects a Mobile Node, it composes an agent advertisement having one or more fields including one or more parameter values. The Foreign Agent then sends the agent advertisement to the Mobile Node. The Mobile Node may then select one of the Foreign Agents, as well as prioritize the Foreign Agents, using the parameter values.

  • Multiple virtual router group optimization
    Patent number: 7486610
    Abstract: Methods and apparatus to transition between four states that include a new state, a listening state, a standby state, and an active state. A router includes a plurality of virtual ports. The virtual ports include a master virtual port and one or more client virtual ports. In general, a selected one of the transitions is initiated after occurrence of an event, wherein the initiating of the selected transition is performed only with respect to the master virtual port. When a selected one of the transitions is initiated with respect to the master virtual port of the router, the selected transition is mimicked with respect to the one or more client virtual port(s) of the router.
