Answer true or false to the following questions and briefly justify your answer: With GBN, it is possible for the sender to receive an ACK for a packet that falls outside of its current window.
Akash M.
As discussed in the textbook, each packet has 8000 bits, the link speed is 1 Gbps, and the propagation delay is 15 ms each way. ACKs are sent whenever a packet arrives, and the ACKs are small, so the transmission time of an ACK can be ignored. How big would the window size have to be for the channel utilization to be greater than 98 percent? That is, how big would the window need to be so that packets are being transmitted 98% of the time?
Consider using IPsec to send a stream of packets from Host A to Host B. For each packet sent in the stream, a new SA is usually created. Is this statement true or false?
