Because a multicast data server or broadcast disk can have clients of very different network capacities, the server needs to offer its repository of data items at a variety of transmission speeds to service clients' varied requests. In this paper, we study how to slice a server's available outgoing network capacity into data channels, how to assign the server's data to those channels, and how to assign clients to the channels given clients' varied requests and download speeds. We find that good choices in this area can improve performance for clients by three-fold or more, and surprisingly, finding the good choices do not require advance knowledge of clients' exact download speeds, once we have chosen the slowest client speed we want to support.
