    摘要: A method and apparatus for quickly determining the status of a network device in a network communicates status inquiry messages over the forwarding plane of one network device to at least one neighboring network device. The status inquiry messages indicate the connectivity status with at least one neighboring device. The status inquiry messages are transmitted periodically to the at least one neighboring device. In addition, the network device may communicate an advertisement message over the control plane to discover the at least one neighboring network device prior to the communication of the status inquiry messages over the forwarding plane. The network devices may negotiate communication parameters for the exchange of status inquiry messages with the at least one network device.

    摘要: Systems, methods, and computer program products that facilitate the integration and accounting of advertising within audio Web content requested by users via telephone devices are provided. Upon receiving a request from a user for Web content via a telephone device, a Web server retrieves an advertisement from an advertisement server, inserts the retrieved advertisement within the user requested Web content, and forwards the user requested Web content and advertisement to a text-to-speech transcoder for conversion to an audio format. The text-to-speech transcoder converts the Web content and advertisement from a text-based format to an audio format and serves the Web content and advertisement in the audio format to the user client device via a telephone link established with the user client device. If an advertisement is interactive, a text-to-speech transcoder may be configured to notify an advertisement server of user interaction with the advertisement. Information such as an identification of a requesting client device, user, as well as time and date information, may be recorded by an advertisement server for use in measuring effectiveness of a particular marketing and/or advertising campaign. Information associated with providing a user with additional information associated with an advertisement may also be stored.

    摘要: A system, device, and method for supporting multiple virtual private networks in an MPOA/NHRP communication network involves encoding a Virtual Private Network (VPN) identifier in certain MPOA/NHRP control messages in order to associate those MPOA/NHRP control messages with a particular VPN, and using an in-band signaling technique to add/remove VPNs to/from a connection. Packets from multiple VPNs are multiplexed over the connection. Each packet is associated with a particular VPN. If packets do not inherently include information from which the VPN can be ascertained, then a VPN identifier is encoded in the packet. The VPN identifier may be encoded in the packet via a tagging mechanism, in which each VPN is associated with a unique tag, and a tag is included in each packet. The VPN identifier may alternatively be encoded in the packet by including the VPN identifier in the packet, for example, in a header (such as an LLC/SNAP header) within the packet.

    摘要: A control system for an engine having a catalytic converter includes an energy calculation module that calculates a calculated mass air flow (MAF) of intake air of the engine based on a requested torque and a requested spark timing that correspond to a desired thermal energy of exhaust of the engine, and that determines an expected thermal energy of the exhaust based on the calculated MAF, and an energy residual module that determines a thermal energy residual of the exhaust based on the expected thermal energy and an estimated thermal energy of the exhaust, wherein the estimated thermal energy is based on a measured MAF of the intake air. The control system includes an energy evaluation module that determines a diagnostic result that indicates whether the catalytic converter is operating within a target temperature range based on the thermal energy residual. Related control methods are also provided.
