Sliding Window Protocol:

Networking Quizzes Computer Networks Test

Question:
We have two hosts A and B that are using sliding window protocol for flow control, and to transfer data from A to B full duplex link is used. The send window size and receive window size is 5 packets each. Data packets that are sent only from A to B are all 1000byte long and the transmission time for such a packet is 50s. Acknowledgement packets that are sent only from B to A are very small and it requires negligible transmission time. In this communication the maximum achievable throughput, if the propagation delay over the link is 200s, is:

Option A):
11.11 x 10⁶ bps
Option B):
10.09 x 10⁶ bps
Option C):
9.12 x 10⁶ bps
Option D):
12.33 x 10⁶ bps

Correct Answer is Option A):
11.11 x 10⁶ bps
