Tcp questions
Consider a client has established TCP connection with a server and sending data. The propagation delay is 5 ms and there are no timeouts and errors during transmission. The size of the receiver advertised window is 128 KB, the slow-start threshold at the client is 64 ... = 10 ms. What is the size of the congestion window (in KB) at time 90 ms after all acknowledgements are processed?
