Question :
1. A server with an upload rate of 5,000 bits/sec must distribute a 10,000 bit file to 20 clients. Each client has a download rate of 4,000 bits/sec. What is the minimum time required to distribute the file to all the clients under the client-server model?
2. A peer-to-peer system consists of a server (containing a copy of a file), and 20 peers. The file size is 10,000 bits, the upload rate of the server is 5,000 bits/sec., and the upload rate of each peer is 2, 500 bits/sec. The download rate of each peer is 4,000 bits/sec. What is the minimum time required to distribute the file to all the peers under the peer-to-peer model?
