摘要： Available bandwidth utilization during transfer of large files over a TCP/IP network is improved by load balancing data streams and dynamically controlling the number of data streams utilized. A determination is made of the optimum number of data streams for a particular data file transfer in the early stage of transmission. An initial number of data streams, which is one unless otherwise specified or determined, is used to transmit one or more file segments, each on a different data stream, immediately followed by a second initial number of data streams, which is at least two greater than the initial number of data streams, is used to transmit another portion of the large data file. During each transmission, individual and aggregate transmission bandwidths are determined. Responsive to a determination that the latest aggregate transmission bandwidth is significantly different from the previous aggregate transmission bandwidth, the number of data streams is modified.

摘要： Available bandwidth utilization during transfer of large files over a TCP/IP network, is improved by segmenting the file and concurrently transmitting portions in an optimal number of logical distinct data streams which may all utilize a single physical medium and communications path. An initial number of data streams, is used to begin transmission of segments, each on a different data stream. During the first seconds of the transfer, individual and aggregate transmission bandwidths are determined, together with a backbone limit computed from the sliding window and round trip times. If the individual transmission bandwidths are approximately equal to the backbone limit, additional data stream(s) and segment(s) are started. Individual and aggregate transmission bandwidths are again determined, and the process is repeated until no substantial increase in aggregate bandwidth is achieved by adding an additional data stream. Aggregate transmission bandwidths are checked upon completion of each segment to determine if a data stream should be terminated.
