Consider sending a packet of 500,000 bits over a path of 5 links. Each link transmits at 50 Kbps. The network is lightly loaded so that there are no queuing delays. Suppose each link is 1Km long, and suppose the propagation speed along the links is 2 x 108 meters/sec. Suppose the network is a packet-switched datagram network and a connectionless service is used. How long does it take to send the packet from source to destination? Show all your work
