Dualog Network Control - Bandwidth Priority


Bandwidth priority configuration enables the customization of firewall rules to regulate the amount of bandwidth allocated to specific traffic.

There are four priority levels to choose from: High, Medium, Low, and Block.


When Dualog Network Control selects a rule to enforce, the priority field becomes significant. If the priority is set to "Block," the request is outright halted. For web requests (on port 80), a message is sent back to the user, clarifying that the request was blocked by Network Control.

For priorities other than "Block," such as Low, Medium, or High, traffic governed by these rules will share bandwidth with other traffic of the same priority. For instance, if two crew members are browsing the internet and both are assigned Medium priority, they will jointly utilize the bandwidth allocated for Medium priority traffic.

Active utilization of priorities can be advantageous for ensuring that critical traffic receives appropriate bandwidth. However, a drawback is that some bandwidth is reserved for prioritized traffic, even when no prioritized traffic is active.
