Webiperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the bandwidth, loss, and other parameters. The destination indicates the size of the receiver window through the TCP header. This advertises the amount of data that it can receive and enables the congestion window to determine the amount of data it can reliably transmit without an ACK. Once received, the data is stored in the receiver buffer and the … Meer weergeven Network congestion occurs when packets sent from the source (the server) exceed what the destination can handle (the user). When the buffers get filled up at the destination, the packets are temporarily stored in … Meer weergeven In slow start congestion control, TCP increases the window’s size rapidly to reach the maximum transfer rate as fast as possible. This self-imposed window size increases … Meer weergeven The rate of transmitting data in a TCP connection is determined by the rate of incoming ACK, which is dependent on the bottleneck in the round-trip path between the sender and the receiver.
