Amessage of length 8x106 bits is to be sent from host a to host b, routed through 2 packet switches. the transmission capacity of each of the three links is 2 mbps. ignoring propagation, queuing and processing delay, how long will it take to move the message as a single packet from host a to host b assuming each packet switch uses store-and-forward switching? how long will it take if the message is broken into 10,000 bit packets?
