Bandwidth Management
This chapter contains information about configuring bandwidth management, editing rules and viewing the ZyXEL Device’s bandwidth management logs.
15.1 Bandwidth Management Overview
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an application and/or subnet. You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to different bandwidth rules.
The ZyXEL Device applies bandwidth management to traffic that it forwards out through an interface. The ZyXEL Device does not control the bandwidth of traffic that comes into an interface.
Bandwidth management applies to all traffic flowing out of the router, regardless of the traffic's source.
Traffic redirect or IP alias may cause
The sum of the bandwidth allotments that apply to any interface must be less than or equal to the speed allocated to that interface in the Bandwidth Management > Summary screen.
15.2
You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E- mail and Video for example).
15.3
You can create bandwidth classes based on subnets.
The following figure shows LAN subnets. You could configure one bandwidth class for subnet A and another for subnet B.
