"two stations communicate via a 1-mbps satellite link with a propagation delay of 279 ms. the satellite serves merely to transmit data received from on station to another, with negligible switching delay. using hdlc frames of 1024 bits with 3-bit sequence numbers, what is the maximum possible data throughput, that is, what is the amount of data bits transferred using hdlc frame per second?"

The answer is ""

Explanation:

The

Transmit station can controls at most 7 frames in 3 bit sequence and without act total time to transmit.

Total time (t) = time for first frame + 2(frame delays)

during the time t frame sent = 7 So, data on each frame is

frame = frame size - ( flag + address+control+fcs bits +flag hits)

frame = 1024 -(8+8+8+16+8)

frame= 976 bits frame

you have to email it to yourself from your phone then download it to either google drive or you computer files. then you can go to where ever you saved it and select it and then copy and paste it. or you could attach it to your question when you are writing it which would be much easier. for example: go to the attachment.
