Thanks to the versatile bandwidth management features included in all our models, the Clavister Security Gateway 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 Clavister Security Gateway is superior in guaranteeing Quality of Service.

Clavister ’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 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.


With Clavister Security Gateway bandwidth management you can prioritize different network segments. The dynamic balancing makes it possible to give the network users maximum network performance when bandwidth is available or otherwise prioritize it according to your wishes.

Furthermore,traffic shaping in Clavister Security Gateway 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.
