  • Patent number: 7965628
    Abstract: A data transmitting method for wireless communication system applied in a transmitting device for transmitting a number of data packets to a receiving device is provided. Firstly, n data packets are transmitted to the receiving device during the first time period, wherein n is a nature number. Next, the first accumulated number is recorded, wherein the first accumulated number denotes the times of resending the n data packets during the first time period. Then, determine that whether the first accumulated number exceeds a predetermined value or not. If the first accumulated number exceeds the predetermined value, then other communication methods are adopted and the method carries on transmitting the remaining data packets; if the first accumulated number does not exceed the predetermined value, the first accumulated number is cleared, and the method carries on transmitting the remaining data packets to the receiving device.

  • Patent number: 7965729
    Abstract: Transferring data (such as files) on an end-to-end, high-speed packet-switched network connection (a “virtual circuit”) or on a circuit. An out-of-band path is used for signaling and status messages (control). The same, or a separate, out-of-band path may be used to retransmit chunks of data that were received with errors or that were not received at all. By simplifying the data being sent over the high-speed (virtual) circuit, the resources of the (virtual) circuit are used efficiently since less overhead is required. Further, since the size of the file to be transferred can be predetermined, and since any retransmissions can be made over a path other than the (virtual) circuit, the (virtual) circuit that best meets the needs of the data transfer can be selected, thereby further increasing the efficiency with which the (virtual) circuit is used.

  • Patent number: 7957280
    Abstract: Classification and verification of static file transfer protocols is provided. A network node sitting in the path of packets classifies traffic according to its content, and then statistically verifies that the content actually matches the initial classification. Classification and verification are standard building blocks in networks systems that provide quality-of-service. However, unlike traditional quality-of-service building blocks, a system of the present invention takes a trust-but-verify approach, and thus can rely on longer-timescale statistical online or offline verification to reduce computational requirements. This improves scalability and reduces the cost and complexity that in part has prevented prior service differentiation systems from succeeding in the Internet. Internet Service Providers (ISPs) can combine the classification and verification building blocks with a networked directory service to allow further classification as to whether particular content is for pay.

  • Patent number: 7929551
    Abstract: A network bridge connects a host device, such as digital media player, cell phone or camera, to content sources over a network to permit the host device to transmit or receive digital media. The network bridge includes a network interface module that identifies at least one media source as well as digital media available on the network. A host device interface module receives, from the host device, file system requests in accordance with a protocol, such as a mass storage protocol. In response to the request, a host device protocol interface module on the network bridge translates the file system request to a request for digital media. The network interface module acquires digital media from the media source, and the host device interface module transfers the digital media to the host device in accordance with the interface protocol. The network bridge may connect to one or more services that provide content to the host device. For example, the services may be accessible over the Internet.
