Q. 28 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 ms . Acknowledgment packets
(sent only from B to A), are very small and require negligible transmission time.
The propagation delay over the link is 200 ms . What is the maximum achievable
throughput in this communication ?
(A) 7.69 × 106 bytes per second
(B) 11.11 × 106 bytes per second
(C) 12.33 × 106 bytes per second
(D) 15.00 × 106 bytes per second
Answer: (B)
