    摘要： A method and system for directing data transfers between applications and devices residing on different computers or devices using an adaptive flow control protocol has been described. When an application or device requests to transfer data with another application or device, adaptive flow control protocol adapts the way data is transferred by observing when an application that is receiving data posts a receive buffer and detects the receive buffer's size. Based upon the application's or device's behavior, the adaptive flow control protocol transfers the data in a mode that is best suited for the application.

    摘要： A method is provided for transferring control between a first network interface and at least a second network interface in a same multiple network interface device after the first network interface transmits an identifier generated by the first network interface. The method includes receiving a message from the second network interface to a program component, the message indicating the reception of the identifier from a second device. Next, the method provides for querying the first network interface to supply the program component with a list of identifiers generated by the first network interface and associated memory locations in the multiple network interface device memory. If the identifier received by the second device is present in the list, the method provides for transmitting a memory location associated with the identifier to the second network interface.

    摘要： An access control mechanism in a network connecting one or more sink devices to a server providing audio/visual data (A/V) in streams. As a sink device requests access, the server measures available bandwidth to the sink device. If the measurement of available bandwidth is completed before the sink device requests a stream of audio/visual data, the measured available bandwidth is used to set transmission parameters of the data stream in accordance with a Quality of Service (QoS) policy. If the measurement is not completed when the data stream is requested, the data stream is nonetheless transmitted. In this scenario, the data stream may be transmitted using parameters computed using a cached measurement of the available bandwidth to the sink device. If no cached measurement is available, the data stream is transmitted with a low priority until a measurement can be made. Once the measurement is available, the transmission parameters of the data stream are re-set. With this access control mechanism, A/V streams may be provided with low latency but with transmission parameters accurately set in accordance with the QoS policy.

    摘要： A novel packet filtering and processing mechanism solves bandwidth estimation problems related to cross-traffic, host limitations, and fabric-specific issues in order to accurately estimate bottleneck bandwidth in fluctuating environments such as home networks. In particular, the process controls the number of packet train experiments, the size of trains and packets within trains, and other factors to eliminate errors due to cross-traffic, network capture, receiver CPU overload, interrupt moderation, and other networking factors. In an embodiment of the invention, a history window is applied to estimates derived from individual trains to ensure that data used to make a bottleneck bandwidth estimate was taken at a time when the network is relatively stable.

    摘要： The present invention extends to methods, systems, and computer program products for increasing the accuracy and efficiency of admission control for data streams. A transmitting computer system transfers a companion data stream along with a variable rate data stream to simulate the maximum data transfer of the variable rate data stream. Accordingly, active probing experiments conducted at other computer systems receive a more accurate indication of the available bandwidth (or bandwidth that may be available in the future). Computer systems can maintain admission control caches that indicate the results of previously conducted active probing experiments and the network configuration when previous data streams where admitted to a network. Computer systems can refer to an admission control cache when performing admission control to increase the efficiency of admission control. That is, an admission control decision can be made without having to conduct a complete active probing experiment.

    摘要： To improve upon existing Winsock implementations, the claimed system and method adapts an existing Winsock system to use out-of-process NSP services. The claimed method and system provides asynchronous Winsock Next calls to provide client application processing flexibility. Further, the claimed method and system provides additional structures for passing additional NSP specific information for a result set to enable further client functionality. One embodiment of the claimed system provides additional client Winsock API functions to aggregate and manage asynchronous calls to multiple NSPs and/or multiple namespaces.
