  • Method and apparatus for virtual private networks
    Patent number: 7653074
    Abstract: A method and apparatus for virtual private networks (VPNs) is described. A computer implemented method comprises determining a set of endpoints for a generic routing encapsulation (GRE) tunnel, determining a key (the key corresponding to a VPN), dynamically establishing the GRE tunnel with the set of endpoints and the key, and processing a set of GRE traffic for the VPN.

  • Method and apparatus for associating PVC identifiers with domain names of home gateways
    Patent number: 7366189
    Abstract: A method and apparatus associates a domain name of a home gateway with one or more PVCs. After the PVC is established, a tunneling protocol is used to request the domain name of the home gateway, and the domain name is associated with the PVC. When a user logs on via an access communication device, the user will provide a domain name of a home gateway with which the user desires to communicate. A PVC associated with the home gateway is then used to allow the user to communicate with the home gateway. The domain name of the home gateway may be periodically verified to detect any changes.

  • System and Method for Identifying a Subscriber for Connection to a Communication Network
    Publication number: 20070168531
    Abstract: A system for identifying a subscriber includes an access server coupled to a number of subscribers using a first communication network and further coupled to a second communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the first communication network. The memory stores path information that identifies a virtual circuit assigned to the particular subscriber. The processor identifies the particular subscriber for connection to the second communication network based upon the path information and the particular virtual circuit used to receive the communication from the particular subscriber.
