2.4.4. Bandwidth

Network bandwith is important for communication among Satellites, Proxies, and Clients. To accomodate high volume traffic, Red Hat recommends a high bandwidth on a network capable of delivering packages to many systems and clients. As a guide, Red Hat provides a set of estimates for package transfer from one system to another over various speeds.
