4. Go back N: Suppose Host A and Host B use

4. Go back N: Suppose Host A and Host B use a GBN protocol with window size N=3 and a long enough range of sequence numbers. Assume host A sends six application messages to Host B and that all messages are correctly received, except for the first acknowledgement and the fifth data segment. Draw a timing diagram, showing the data segments and the acknowledgements sent along with the corresponding sequence and acknowledgement numberrs, respectively
