A message of size 64KB is to be send from the source to the destination. The network limits packets to a maximum size of 2KB, and each packet has a 32-byte header. The sending channels in the network have a bit error rate of 10-6, and Stop-and-Wait ARQ is utilized in all the transmission lines. How long does it take on the average to send the message from the source to the destination? Make an assumption that the signal travels at a speed of 2 x 105 km/second.
