Question

A path in a digital circuit-switched network has a data rate of 1mbps. The exchange of 1000 bits is required for the setup and teardown phases. The distance between two parties is 5000kms. What is total delay if 50000bits of data are exchange during data transfer phase and the propagation speed is 2x108 m/s?

Answer 1

Here is your answer:

The total delay if 50000bits of data are exchange during data transfer phase and the propagation speed is 2x108 m/s

_______________

Answer 2

Answer:

78ms

Explanation:

3[(5000km)/ (2 × 10^8 m/s)] +3[(1000 bits /1 mbps)] = 75 ms + 3 ms= 78ms

we assume that data is transfer is in one direction , the total is delay is then delay for set up and tear down + propogation delay + transmission delay

FINAL ANSWER- 78 ms
