Problem:
TCP connection
Consider a TCP connection between two points that are 200 km apart. Assume the transmission speed is 10 Mbps (10 x 2^20 bps) and the propagation speed is 200 x 10^8 meters/s. Assume 16-bit sequence number. The TCP initially sends a segment of 1024 bytes and each time it receives an ACK it doubles the number of segments it sends until the full capacity is reached.
Required;
Question 1: Calculate the initial RTT, assuming there is no other delay besides the transmission delay and propagation delay.
Question 2: How long does it take to reach its full capacity?
Question 3: What is the maximum throughput?
Question 4: At full capacity, how long does it take for the sequence number to wrap around?
Please show all calculations.
