bandwidth, implying that all of the bottlenecks are in access networks. We also suppose
that the server and clients are not participating in any other network applications,
so that all of their upload and download access bandwidth can be fully
devoted to distributing this file.
Let’s first determine the distribution time for the client-server architecture,
which we denote by Dcs. In the client-server architecture, none of the peers aids in
distributing the file. We make the following observations:
