Dualog Network Control - Bandwidth Priority

INTRODUCTION

Bandwidth Priority Configuration allows you to customize firewall rules to control how bandwidth is allocated to specific types of traffic.

There are four available priority levels:

• High
• Medium
• Low
• Block

HOW IT WORKS

When Dualog Network Control applies a rule, the configured priority level determines how the traffic is handled.

If the priority is set to Block, the request is immediately denied. For web traffic (port 80), the user will receive a message indicating that the request has been blocked by Network Control.

For other priority levels, such as Low, Medium or High—traffic is allowed and shares bandwidth with other traffic assigned to the same priority. For example, if two crew members are browsing the internet with Medium priority, they will share the bandwidth allocated to that level.

Using priorities effectively helps ensure that critical traffic is given sufficient bandwidth. However, one limitation is that bandwidth may be reserved for prioritized traffic even when it is not actively in use.

CONFIGURATIONS

1. Login to Dualog Portal with your administrator account. On the top left, click on menu button > Connection suite > network control
2. Click on 'Configure network control' and select vessel to be configured.

3. Under the Setup tab, scroll down to Bandwidth Priority. Here, you can define how much bandwidth to allocate for Low, Medium, and High priorities.

4. Before configuring these values, it is recommended to confirm your CIR (Committed Information Rate) with your airtime provider to ensure optimal settings.
