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 $$\mu $$s Acknowledgement packets (sent only from B to A) are very small and require negligible transmission time. The propagation delay over the link is 200 $$\mu $$s. What is the maximum achievable throughput in this communication?
