System And Method For Improving An Aggregated Throughput of Simultaneous Connections

A client and content provider are connected by a plurality of simultaneous transport connections. The number of the transport connections that are used to transfer data is selected based on the size of the data to be transferred and may change after transfer of data has commenced based on the amount of data left and the attributes of the transport connections. In another aspect, data to be transmitted over the transport connections is organized into frames such that each frame includes data from only one data stream. The frames are sized to be less than or equal to a control window of the transport connection over which they are transmitted. Each frame may be assigned to a transport connection in a round robin fashion or based on the size of the frame and the sizes of the control windows of the transport connections. 1. A system for increasing an aggregated throughput between computers over a computer network , the system comprising: receive one or more requests for data delivery to a second computer through a plurality of simultaneous transport connections between the first computer and the second computer;', 'proceed with delivering requested data corresponding to the one or more requests for data delivery through at least a portion of the plurality of simultaneous transport connections to the second computer;', 'evaluate an amount of the requested data remaining to be delivered to the second computer; and', 'while delivering the requested data, 'reduce a number of the plurality of simultaneous transport connections in the at least the portion of the simultaneous transport connections used to deliver the requested data to the second computer in response to a decrease in the amount of the requested data remaining to be delivered to the second computer., 'a first computer including a processing device including one or more processors, one or more memory devices coupled to the one or more processors and encoded with instructions that when executed by the one or more ...
