WebTCP Window Size Scaling. TCP (Transmission Control Protocol) is a connection oriented protocol which means that we keep track of how much data has been transmitted. The sender will transmit some data and the receiver has to acknowledge it. When we don’t receive the acknowledgment in time then the sender will re-transmit the data. WebThere are several factors which affect the initial TCP window size: Here is the relevant code in kernel 2.6 of Red Hat Enterprise Linux: Generally, if the MSS is 1460 bytes, the initial window size is going to be 5840 (1460 * 4), although there are still other factors that could change the size.
