  • Publication number: 20090285204
    Abstract: An approach for providing telephony services over a data network is disclosed. A communications system includes a location server that receives a request from a calling station to establish a call with a station associated with a called party. The location server generates a message specifying a set of addresses relating to the called party and context information. A proxy server communicates with the location server and is configured to receive the message and to attempt to establish the call based on the set of addresses. The proxy server iteratively queries the location server to obtain another set of addresses if no prior address results in establishment of the call.

  • Publication number: 20090110174
    Abstract: In a SIP network, SIP servers are provisioned with information used to authenticate subscribers and entities that will be placing calls. This information can be used during call establishment to allow or deny calls, as well as to determine the appropriate party to bill if the call involves a charge, such as a long distance charge. In addition to allowing calls between authenticated and trusted entities, there is a need for the SIP server to allow certain kinds of calls that involve non-trusted users or entities. If non-trusted entities where not recognized, trusted users and entities within the SIP network would not be able to receive calls from users or entities not know to the SIP server that is providing them services.

  • Publication number: 20060156402
    Abstract: An approach for tracking denial-of-service (DoS) flood attacks using an overlay IP (Internet Protocol) network is disclosed. One or more tracking routers form an overlay tracking network over the network of an Internet Service Provider (ISP). The ISP network includes numerous transit routers and edge routers. The tracking routers communicate directly with all the edge routers using IP tunnels. The edge routers within the ISP network perform security diagnostic functions, in part, to identify a DoS flood attack that has been launched by one or more attackers. To track down an attacker, an egress edge router identifies the DoS flood attack datagrams, rerouting these datagrams to the overlay tracking network. The tracking routers perform hop-by-hop input debugging to identify the ingress edge router associated with the source of the DoS flood attack.

  • Publication number: 20050159883
    Abstract: A device tracking location adherence and route adherence technology, is disclosed that at least provides a tracked device receiving, a set of coordinates associated with a boundary area, and obtaining a position of the tracked device. Based upon the received coordinates and the detected position of the tracked device, a determination is made as to whether the tracked device is located inside the boundary area or outside the boundary area. An alert signal is then generated and transmitted if the result of the determining is different from an immediately previous obtained result. The system allows, for example, drastic reduction in the amount of data traffic required within a system since the tracked device performs much of the necessary processing. This is especially advantageous where a fleet of tracked devices are employed within a network.
