Question: (a) Suppose a city of one million inhabitants builds a data network. Suppose that each inhabitant, during the busiest hour of the day, is involved in an average of 4 transactions per hour that use this network (such as withdrawing money from a cash machine, buying some item in a store and thus generating an inventory control message, etc.). Suppose that each transaction, on the average, causes 4 packets of 1000 bits each to be sent. What is the aggregate average number of bits per second carried by the network? How many 64 kbit/sec voice telephone links are required to carry this traffic assuming that each packet travels over an average of 3 links?

(b) Suppose that the inhabitants use their telephones an average of 10% of the time during the busy hour. How many voice telephone links are required for this, assuming that all calls are within the city and travel over an average of three links?
