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?

MTU question from computer networks
Consider an IP packet with a length of 4,500 bytes that includes a 20-byte IPv4 header and a 40-byte TCP header. The packet is forwarded to an IPv4 router that supports a Maximum Transmission Unit (MTU) of 600 bytes. Assume that the length ... fragment will be 600 Bytes. The last fragment size will be 468 Bytes. The fragment offset in the second fragment is 144.

Does TCP uses negative acknowledgement?
Does TCP use negative acknowledgment? According to me for flow control TCP uses a mix of both SR and GO BACK N protocol, and SR protocol uses negative acknowlegment thus TCP can use negative acknowlegement. Am I right?
