Question: Consider two hosts, one is located on the west coast of the US and the other is located on the east coast. The speed-of-light Round-Trip

Consider two hosts, one is located on the west coast of the US and the other is located on the east coast. The speed-of-light Round-Trip propagation Time (RTT) between these two hosts is 20 ms (millisecond). Suppose that they are connected by a channel with the transmission rate, R, of 1Gbps (10^9 bits per second). These two hosts run a pipelined/sliding-window protocol where the size of a packet is 1200 bytes (1 byte = 8 bits), including both header fields and data. How big would the window size at least have to be for the channel utilization to be greater than 70%? You may round up the answer to the closest integer.(Step-by-Step) Justifications:
