Question

2. 3. A 2500-km long T1 trunk is used to transmit 128-byte frames using protocol 5. a) If the propagation speed is 6 microseconds/km, how large should the window size be? b) How many bits should the sequence numbers be? (We want the minimum number of bits here needed to support the window size.) 3. Frames of 1500 bits are sent over a 1-Mbps channel using a geostationary satellite whose propagation time from the Earth is 250 ms. Acknowledgements are always piggybacked onto data frames. The headers are very short. Three-bit sequence numbers are used. What is the maximum achievable channel utilization for:

Explanation / Answer

Hey, I have your solution. Please rate with 5 stars :)

Propagation time = 6 usec/km
