Consider a three hop network from the source to the destination. Let m be the packet transmission time at each hop. Let n be the propagation delay at each hop. Assume there is no queuing delay and processing time at each hop. Based on store-and-forward, What is the total time for the packet to be transmitted to the destination?
1) m + n
2) 3m + n
3) 3m + 3n
4) None of the above
