$3.$ Consider distributing a file of F $=15$ Gbits to N peers. The server has an upload rate of us $=64$ Mbps$,$ and each peer has a download rate of di $=4$ Mbps and an upload rate of u$.$ For N $=10,100,$ and $1,000$ and u $=320$ Kbps$,800$ Kbps$,$ and $4$ Mbps$,$ prepare a chart giving the minimum distribution time for each of the combinations of N and u for both client$-$server distribution and P$2$P distribution.
