Host A is sending data to host B over a full duplex link. A and B are using the sliding window protocol for flow control. The send and receive window sizes are $5$ packets each. Data packets $($sent only from A to B$)$ are all $1000$ bytes long and the transmission time for such a packet is $50$s$.$ Acknowledgment packets $($sent only from B to A$)$ are very small and require negligible transmission time. The propagation delay over the link is $200$ us$.$ What is the maximum achievable throughput in this$$communication$?$
