Patent number: 7958556Abstract: A method and apparatus is disclosed for increasing the security of computer networks through the use of an Intrusion and Misuse Deterrence System (IMDS) operating on the network. The IMDS is a system that creates a synthetic network complete with synthetic hosts and routers. It is comprised of a network server with associated application software that appears to be a legitimate portion of a real network to a network intruder. The IMDS consequently invites inquiry and entices the intruder away from the real network. Simulated services are configured to appear to be running on virtual clients with globally unique, class “C” IP addresses. Since there are no legitimate users of the virtual network simulated by the IMDS, all such activity must be inappropriate and can be treated as such. Consequently, the entire set of transactions by an intruder can be collected and identified rather than just those transactions that meet a predefined attack profile.Type: GrantFiled: November 1, 2004Date of Patent: June 7, 2011Assignees: Verizon Corporate Services Group Inc., Level 3 Communications, LLC, Raytheon BBN Technologies Corp.Inventors: Martin F. Roesch, Ronald J. Gula

Patent number: 7953888Abstract: Methods and apparatus are disclosed for dynamically discovering and utilizing an optimized network path through overlay routing for the transmission of data. A determination whether to use a default network path or to instead use an alternate data forwarding path through one or more overlay nodes is based on real-time measurement of costs associated with the alternative paths, in response to a user request for transmission of message data to a destination on the network. Cost metrics include delay, throughput, jitter, loss, and security. The system chooses the best path among the default forwarding path and the multiple alternate forwarding paths, and implements appropriate control actions to force data transmission along the chosen path. No modification of established network communication protocols is required.Type: GrantFiled: July 30, 2003Date of Patent: May 31, 2011Assignee: Level 3 Communications, LLCInventor: Livio Ricciulli

Patent number: 7949662Abstract: In a data processing system, a method includes deleting a particular copy of a data item when at least one other copy of the data item is available. The presence of another copy of the data item is determined, at least in part, based on an identifier for the data item, the identifier having been computed using all of the data in the data item and only the data in the data item, wherein two identical data items in the data processing system will have identical identifiers. The particular copy of the data item may be deleted if another copy of the data is determined to be present on another processor in the system or on the same processor. The identifier of the data item is computed using a function such as a message digest or hash function which may be: MD4, MD5, or SHA.Type: GrantFiled: December 23, 2003Date of Patent: May 24, 2011Assignees: Kinetech, Inc., Level 3 Communications, LLCInventors: David A.

Patent number: 7949779Abstract: A plurality of content providers provide multiple resources to multiple clients. At least some of said resources are to be served to clients from a shared content delivery network (CDN) formed by a plurality of repeater servers. Each content provider provides at least some resources via one or more content sources associated with that content provider. Amounts of data transmitted by the CDN on behalf of each of the plurality of content providers are monitored. Based at least in part on said monitoring, requests for resources are selectively delivered at a lower transmission rate. The lower transmission rate is achieved by generating pauses or delays in the transmission.Type: GrantFiled: October 31, 2007Date of Patent: May 24, 2011Assignee: Level 3 Communications, LLCInventors: David A.

Patent number: 7941514Abstract: An order entry system communicates with the customer over a user interface and works with an automated installation system for installing network service. The order entry system prompts the customer to place a new service order. The service parameters of the new service order are passed to the installation system. The order entry system notifies the customer of the route and prompts the customer to add a service order for the route to the customer order. If the customer adds the service order to the customer order, the order entry system prompts the customer to reserve the service order or to submit an order for the service. If the customer reserves or submits an order for the service, the order entry system request the installation system to design an actual communication line circuit to satisfy the order.Type: GrantFiled: July 31, 2002Date of Patent: May 10, 2011Assignee: Level 3 Communications, LLCInventors: Richard L.

Publication number: 20100284307Abstract: A communication line is installed in a network by automating a design phase and a configuration phase for the service and by automating failure recovery in either of the phases. In the design phase, an optimal route for the communication line is found, and the network components are provisioned and assigned. If the assigned network components are not available or can not be validated, the components causing the failure are marked, and the design phase is retried without the marked components. After the design phase, the configuration phase begins. The circuit design is tested against actual network components. If the test is passed, the actual network is configured according to the circuit design and the circuit is activated. If there is a network component failure during the configuration phase, the good route elements in the design are released while the failed network components are marked. The design phase is retried.Type: ApplicationFiled: July 19, 2010Publication date: November 11, 2010Applicant: Level 3 Communications, LLCInventors: Richard L. Wall, Gary L. Ryczek, James A.
