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?

RTO in TCP question
A host sends two packets and receives two acknowledgments. The time is shown as hour:minute:seconds. Segment 1 was sent at 0:0:00. Segment 2 was sent at 0:0:07. ACK for segments 1 and 2 received at 0:0:09. Calculate the value of RTO.

Computer Network
Let host X sends a file a size of 1500 byte to host Y through routers R1, R2, R3 and R4 respectively in two different ways. Each packet contains 100 bytes of header information along with the user data. Assume that the bandwidth of each link is 107 B/s ... difference between the time taken to send the packet in first case and the time taken to send the packet in second case in μs?

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.
