4. (1 point) Consider a cross-country example where a host in East Coast is connected with another host in West Coast by a channel with a transmission rate of 1 Gbps. The round-trip propagation delay between these two end systems is approximately 90 ms. How big would the window size have to be for the utilization over this channel to be greater than 95%? Suppose that the size of a packet is 2 KB, including both header fields and data
