suppose that the channel transmission rate is 10 Mbps, the RTT is approximately 15 milliseconds, and that the packet size is 1000 bytes.

1. Determine the channel utilization when a stop-and-wait protocol is used.

2. If a pipelined protocol is used, what would be the window size in order for the channel utilization to be greater than or equal to 95%?
