Guarantee bandwidth

You learn how to create a traffic shaping policy that guarantees bandwidth for certain traffic and how to apply that policy.

Introduction

In this example, you want to make sure that 10 MB of your ISP connection is reserved for remote access traffic. For this, you create a traffic shaping policy that guarantees bandwidth based on an application, and apply the traffic shaping policy to an application category.

Create a traffic shaping policy that guarantees bandwidth

You create a traffic shaping policy that limits the bandwidth based on application.

  1. Go to System services > Traffic shaping and click Add.
  2. Enter a name.
  3. Specify the settings.

    All applications with the same application ID share the reserved bandwidth.

    Create a traffic shaping policy that guarantees bandwidth.
  4. Click Save.

Apply traffic shaping policy to application traffic

You link a traffic shaping policy to an application category. This means that in future connections the policy defines the bandwidth for applications of that type.

  1. Go to Applications > Traffic shaping default.
  2. Open the Remote Access category and click Edit.
  3. Select your new traffic shaping policy from the drop-down menu.
  4. Click Save.

The traffic shaping policy is applied to new connections that fall into the remote access application category. The decision is based on the application ID. You can find the application ID of traffic in the application filter log.

Multiple remote access connections share the reserved bandwidth you configured. Depending on the number of connections and the traffic they create, the individual bandwidth varies.
