Consider a wide area network in which two hosts, A and B, are connected through a 100 km communication link with a data speed of 10 Gb/s. Host A wants to transfer a file of size 20 KB while host B has a receive buffer with a capacity of 32,000 bits. Host A starts the three-way handshake and sends a SYN segment, where the initial sequence number is 200 and MSS = 2,000 byte, and host B replies with an initial sequence number of 400 and MSS = 1,000 byte. Sketch the sequence of segment exchange, starting with host A sending data at time =0 and window size = 2 segments. Assume that host B delivers the received data to the application once its buffer is full and that it sends an ACK every two segments.
