Thanks to the versatile bandwidth management features included in all our models, the Amaranten Firewall is the perfect
solution for lowering the cost of bandwidth and making sure that business-critical traffic flows without disruptions.

Also in more complex solutions, where detailed control of the traffic is required, the traffic shaping functionality in your
Amaranten Firewall is superior in guaranteeing Quality of Service.

Amaranten's traffic shaping tool, unlike many other models, is closely integrated with the core firewall functionality. Hence
bandwidth can be limited, guaranteed and prioritized with the granularity of a single firewall rule. All traffic that can be filtered
by the firewall can thus be bandwidth managed. This also includes VPN connections and virtual LANs.

The bandwidth control is performed using up to 64 independent weighted queues or "pipes", where each pipe has eight
different levels of priority with individual limits on bandwidth and packets per second. Pipes may further be subdivided in
order to track individual flows. Traffic flow grouping may be done according to interfaces, IP addresses, networks and
ports. Consequently, an administrator can make sure that any single user cannot use up all all available bandwidth, or
that a server farm is not being overloaded by a few visitors coming in over high-speed Internet connections.

Furthermore, traffic shaping in Amaranten Firewall supports dynamic balancing of bandwidth limits between groups. This
works by automatically adjusting the group limits with respect to bandwidth allocation and the current number of groups.
By using this feature, available bandwidth can be fairly distributed among all users in a network.
