Bandwidth rules determine what connection gets priority over another. ISA Server bandwidth control does not limit how much bandwidth can be used. Rather, it informs the Windows 2000 quality of service (QoS) packet scheduling service how to prioritize network connections. Any connection that does not have an associated bandwidth rule will get a default scheduling priority. On the other hand, any connection with an associated bandwidth rule will be scheduled ahead of default scheduled connections.
When you install ISA Server, you specify the installation mode: firewall, cache, or integrated. Bandwidth rules are available in all installation modes.
