Network Control bandwidth priority

Description

Bandwidth priority configuration allows one to configure firewall rules to set how much bandwidth a firewall rule can use.

There are four levels of bandwidth priority to choose from. High, medium, low and block

Bandwidth levels can be customised to suit your needs.

How it works

When Dualog Network Control has decided on a rule to use – the priority field comes into play. If the priority is set to “block”, the request is simply stopped. If this is a web request (port 80), a message is sent back to the user explaining that the request was blocked by Network Control.

If any other priority is used, Low, Medium or High, traffic according to this rule will share bandwidth with other traffic having the same priority.

If, for example, two crew member are surfing the net and they are given priority Medium, they will have to share the bandwidth allocated for Medium priority.

Using priorities actively can be useful if you want to make sure important traffic is given proper bandwidth. The disadvantage is that some bandwidth will be allocated for prioritized traffic, even if no prioritized traffic is active.
