WebSo, we need to determine how large a range of sequence numbers can be covered, at any given time, by the receiver and sender windows. Suppose that the lowest-sequence number that the receiver is waiting for is packet m. In this case, it’s window [m, m+w-1] and it has received (and ACKed) packet m-1 and the w-1 packets before that, where w is ... WebThe network engineer should propose a window size equal to 24 in this example. Note that Go Back N with N = 1 is exactly ABP. Transmission errors reduce the efficiency of Go Back N. The analysis of the efficiency when errors occur is more complicated. View chapter Purchase book Transmission Control Protocol/Internet Protocol (TCP/IP) WebJul 30, 2024 · The sequence numbers are numbered as modulo-n. For example, if the sending window size is 4, then the sequence numbers will be 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, and so on. The number of bits in the sequence number is 2 to generate the binary sequence 00, 01, 10, 11. The size of the receiving window is 1.
