摘要:
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.

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.

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.

Techniques for exchanging capabilities in a wireless network are provided. In one embodiment, a first device receives a capability message over a communication link from a second device in a WiMAX network. The communication link may be between any combination of base stations and gateways. For example, the R4, R6, or R8 interface may be used. Other interfaces may also be appreciated in a WiMAX network. The capability message includes one or more capabilities supported by a second device in the WiMAX network. Capabilities to support are then determined based on the one or more capabilities. These capabilities will be supported by the first device for communications with the second device. The first device is then configured to support the determined capabilities. Accordingly, the first device is dynamically configured based on the capability message received.

In one embodiment, a method includes receiving a packet at a network processor, and determining the packet is to be directed to a selected one of a plurality of traffic processors if a tunnel endpoint identifier of the packet is associated with a subscriber terminal. The method further includes determining that the packet is to be directed to the selected one of the plurality of traffic processors if a destination address of the packet is associated with the subscriber terminal. The method still further includes distributing the packet to the selected one of the plurality of traffic processors.

According to one embodiment, providing network redundancy includes configuring a session registrant database to have one or more virtual standby states. Each virtual standby state corresponds to an active router. The session registrant database receives session information from the active router(s) and determines that an active router has failed. A virtual standby state corresponding to the failed router is set to a virtual active state. A second router is configured to have a standby state associated with the set virtual active state. The session information received from the failed router is transferred to the second router, and the second router is configured to have an active state.

In one embodiment, sessions are synced from an active device to a standby device according to a priority. One or more attributes are determined for a plurality of sessions that need to be synced between an active device and a standby device. The attributes may be used to determine a value of syncing a session. A priority for syncing the sessions based on the attributes is then determined. The sessions are then synced based on the priority. For example, a portion of sessions considered to be of a higher priority may be synced before a portion of sessions considered to be of a lower priority. Because the sessions considered of a higher priority are synced first, if a double failure occurs where the active device fails during the syncing process, at least the higher priority sessions have been synced with the standby device and the standby device can take over these sessions.

User equipments can download a video file by instantiating multiple video requests, each request specifying different parts of the video file. If each video request initiates a separate transmission control protocol (TCP) session, which is the case with an hypertext transfer protocol (HTTP) partial get request, then a network device in a communications network would be oblivious of contextual information, which indicates that the TCP sessions download different portions of the same video file. This disclosure provides systems and methods for correlating multiple TCP sessions so that a network device in a communications network can be aware of the contextual information.
