Suppose there are 3,000,000 new phone call arrivals
Per minute to the switched telephone system worldwide,
With each call lasting for 5 minutes on average,
And there are 6 hops (i.e. 6 links and 6 nodes) on
Average between the callers and callees. How many
Memory entries are occupied on average to support
The switched connectivity worldwide?
Please help or hint us guys .
