  • Patent number: 7746990
    Abstract: A system and method to provide content and call attributes for a destination phone number using a click-to-dial connection includes accepting a query, retrieving links to a document, and searching through cached data using the query to identify relevant or destination number information. If no match is found, the method continues with accessing the document identified by the link for identifying relevant number information and creating a click-to-dial icon to link to the relevant numbers included in the relevant phone number information identified by the query. Next, a popup box for content relevant to the click-to-dial icon and a click feature on the popup box are created to retrieve call destination attributes for viewing by a user. Further, computer instructions create at least one communication connection between two communication devices after viewing call destination attributes.

  • Publication number: 20100161760
    Abstract: A client computing system includes a processor that receives a domain name and determines if the domain name is in a list of domain names that are associated with a content delivery network (CDN). In response to determining that the first domain name is in the list, the processor directs a domain name system (DNS) request to a CDN DNS server, instead of to the default DNS server.

  • Publication number: 20100161799
    Abstract: A method receives from a first server a first domain name system (DNS) request including a first internet protocol (IP) address of the first server, and a second IP address received by the first server from a first system. The method also maps a correlation between the first IP address and the second IP address, and receives from the first server a second DNS request. In response to receiving the second DNS request, the method responds to the first server with a third IP address of a second server, wherein the third IP address is chosen based upon the second IP address.

  • Publication number: 20100150160
    Abstract: The present invention provides a network system that interworks OA&M (Operations, Administration and Maintenance) failure notification data from the ATM Domain to the Ethernet Domain and vice versa. Failure indications or notifications are typically routed from one domain to another within 1-2 seconds; providing service providers and customers the ability to react quickly to network faults. This enhances the overall quality of the Ethernet-to-ATM Interworking service and provides a similar level of reliability across the Ethernet/ATM/FR domains.

  • Patent number: 7739154
    Abstract: This is a method for use in conducting online and/or proxy-based auctions. This method achieves the best possible price in a timely manner, by more closely simulating the mechanics of a face-to-face auction transaction where bidding is not closed at a preset time but by balancing bid frequency against conducting a timely transaction. The process extends the auction closing time by a geometrically decreasing amount to accommodate bids entered near the end of the auction.

  • Patent number: 7738643
    Abstract: This is a method for use in a teleconference that troubleshoots echo problems. After receiving a code to begin the troubleshooting process, all legs of the teleconference are muted except a test leg. That test leg is evaluated for echo. The process is repeated for each of the legs of the teleconference. After automatically measuring echo on all legs, results are reported to a moderator or host, who can take action such as muting all legs with echo, or discussing remedial action with each participant on a leg with echo.

  • Patent number: 7738164
    Abstract: A multi-band hybrid amplifier is disclosed for use in optical fiber systems. The amplifier uses Raman laser pumps and semiconductor optical amplifiers in series to produce a relatively level gain across the frequency range of interest. Multiple Raman pumps are multiplexed before coupling into the fiber. The Raman amplified optical signal may be demultiplexed and separately amplified by the SOAs before re-multiplexing. Gain profiles of the Raman pumps and the SOAs are selected to compensate for gain tilt and to alleviate the power penalty due to cross-gain modulation in the SOAs. The disclosed hybrid amplifier is especially useful in coarse wavelength division multiplexing (CWDM) systems.

  • Publication number: 20100146076
    Abstract: A provider network is configured to redirect multimedia content between receiver devices associated with a user. Initially, a multimedia stream representative of the multimedia content is transmitted via the provider network to a first receiver device associated with the user. In response to a redirect stimulus, the provider network redirects the streaming of the multimedia content to a second receiver device associated with the user. The multimedia stream transmitted to the second receiver device can be formatted based on the characteristics of the network link between the provider network and the second receiver device, based on specified formatting rules associated with the second receiver device, and the like. The redirect stimulus can include a user-initiated redirect command provided to the provider network via the first receiver device, the second receiver device, or a third device. Alternately, the redirect stimulus can include an automated stimulus generated based on redirect rules.
