    Abstract: A system and method suited for improved overall data transmission having a hardware-based transceiver configured for transmitting upstream data with suppressed data packets. In TCP sessions between devices, a server seeks an “acknowledgement” that the downstream data transmission has been received by a client. Some data packets sent upstream may contain only TCP acknowledgement data and therefore may be combined with other purely TCP acknowledgement data packets in order to reduce the impact of the TCP acknowledgement packets on the overall upstream data throughput. In addition, this results in increased TCP performance in the downstream transmission direction as well because the algorithm enables replacing earlier arriving ACK packets with later arriving ACK packets which allows the device to send all TCP ACK information known to the suppressor at the earliest possible time.

    Abstract: Aspects of the invention provide systems and methods for reducing latency in TCP connections. A client computer may send a request for information to a server computer using TCP. In response, the server may transmit the information to the client device according to default TCP connection assumptions. The server may re-configure the TCP connection based on various network statistics identified by the characteristics of the exchange between the server and the client. The server may periodically provide the network statistics concerning the speed of the network connection between the server and the client to the client. This information may be stored in cache memory by the client device for later use. For example, the next time the client device requests information from the server, the server may request the cached network statistics. The server may use this information to determine how information should be transmitted to the client.

    Abstract: A system and method transmits data so as to reduce latency in the transmissions. In one aspect, a sending device may determine a minimum number N of packets necessary to transmit information to a receiving device. In accordance with this aspect, in addition to transmitting all or some of the N number of packets in a given series, the sending device may additionally transmit one or more duplicate packets, where each duplicate packet contains data duplicative of the data contained in the last or Nth packet transmitted in the series.

    Abstract: A method for controlling data flow by a proxy server connected between a User Equipment (UE) and a content server is disclosed. The proxy server estimates a first amount of data reception indicating an amount of data received by the UE and calculates a second amount of data reception indicating an amount of data received by the proxy server from the content server. The proxy server delays transmission of acknowledgement (ACK) on data received by the proxy server from the content server and waits until a time allowed for the transmission, if the second amount of data reception is greater than the first amount of data reception by a predetermined threshold. The resent disclosure may prevent a waste of network load and unnecessary resources by the proxy server controlling download data rate from the content server.
