(10 pts) Describe how caches reduce response time for client request and reduce traffic on an institutions access link. 10) Compare the two query approaches used in DNS in terms of their strength and weakness. 11. [15 pts] Consider distributing a file of F = 10 Gbits to 1000 peers. The server has an upload rate of us = 50 Mbps, and each peer has a download rate of di = 5 Mbps and an upload rate of u. For u = 100 Kbps, 500 Kbps, and 2 Mbps, prepare a chart giving the minimum distribution time for each u for both client-server distribution and P2P distribution
