2.4 Determining Bandwidth Needs
2.4.1 Determining bandwidth needs

In order to determine the bandwidth needed for each link, one must determine the aggregate average bandwidth of all devices that will use that link. The figure shows a sample network topology that uses both standard Ethernet and Fast Ethernet links. In the following sections, information about user traffic patterns and network connections will be presented and a decision made as to whether or not a Fast Ethernet link will be sufficient.
