    摘要： A system and method are shown for offloading a computational service on a point-to-point connection. When a tunnel initiator network device, such as a Level 2 Tunneling Protocol Access Concentrator (LAC), detects a tunnel client network device, the LAC sets up a tunnel connection with a tunnel endpoint network device, such a Level 2 Tunneling Protocol Network Server (LNS). During a process of establishing a call session on the tunnel connection, the LAC sends its compression capabilities to the LNS. When the LNS detects that the LAC is capable of compressing tunnel packets, the LNS negotiates compression parameters with the tunnel client network device. Subsequently, the LNS transmits the negotiated compression parameters to the LAC that configures a compression engine based on the received compression parameters. Hereinafter, the tunnel client network device will send compressed tunnel packets to the LAC that will decompress the received tunnel packets prior to transmitting the tunnel packets to the LNS on the tunnel connections. Similarly, the LNS will send uncompressed tunnel packets on the tunnel connection to the LAC that will compress the received tunnel packets prior to transmitting the tunnel packets to the tunnel client network device.

    摘要： A system and method for processing packets of information includes an ingress module. The ingress module receives a plurality of packets of information from a first network. The ingress module determines the type of each of the plurality of packets. A route server module is coupled to the ingress module. The route server module sends a distributed processing request to the ingress module. The ingress module receives the distributed processing request and, responsively, performs a first set of processing operations on selected ones of the plurality of packets. The selected ones of the plurality of packets are of a first type. The ingress module forwards others of the plurality of packets of information to the route server module. Each of the others of the plurality of packets are of a type distinct from the first type. The route server module receives the others of the plurality of packets of information and performs a second set of processing operations on the others of the plurality of packets of information.

    摘要： A method for allocating network addresses comprises providing an address pool comprising a plurality of network addresses and then dividing the address pool into a plurality of address sub-pool that comprise a unique subset of the network addresses of the address pool. Each of the sub-pools is available for use by any one of a plurality of routing devices of a network access server. The method then comprises receiving a request to assign a first network address to a first user, allocating a first address sub-pool of the plurality of address sub-pools to a first routing device of the plurality of routing devices and transmitting a first message to the other routing devices to indicate that the first address sub-pool has been allocated. The method additionally comprises assigning the first network address to the first user from the first address sub-pool and advertising an aggregate route for the first address sub-pool over a network.

    摘要： A high density network access server implements a tunneling protocol between a modem module and a route server module. PPP and routing control packets received from the PPP link are tunneled to the route server for processing. The IP data packet forwarding function for the network access server is distributed directly to the modem modules. The combination of distributed PPP processing and distributed IP data packet forwarding enables the capacity of the network access server to be scaled to orders of magnitude greater than previously known, to handle thousands or even tens of thousands of simultaneous data sessions.

    摘要： Systems and methods for bridging packet flows to bypass call legs and/or tunnels are provided. A tunnel initiator, which can be an access gateway, a foreign agent, and a mobility anchor point, for example, provides a bypass for certain packets that have a destination serviced by the same tunnel initiator. The bridge allows the packets to bypass a backhaul loop and reduces latency and frees bandwidth for other purposes in the network. The bridging can be implemented in a tunnel initiator for mobile to mobile packet flows, mobile to land line packet flows, and land line to mobile packet flows. Route optimization can also be provided in certain embodiments.

    摘要： A method and system for redirecting communication traffic of a prepaid subscriber of a wireless network includes determining when the subscriber has exhausted or nearly exhausted his usage quota, identifying a recharging facility to which the subscriber should be redirected to recharge his account balance, and redirecting the subscriber communication traffic to the recharging facility as a result of determining that the subscriber has exhausted or nearly exhausted his usage quota. The redirection can occur during an existing session or during the process of initially establishing a session.
