Bandwidth Pools

On the Quality of Service (QoS) > Bandwidth Pools tab you can define and manage bandwidth pools for bandwidth management. With a bandwidth pool, you reserve a guaranteed bandwidth for a specific outgoing traffic type, optionally limited by a maximum bandwidth limit.

To create a bandwidth pool, proceed as follows:

  1. On the Bandwidth Pools tab, select an interface.

    From the Bound to interface drop-down list, select the interface for which you want to create a bandwidth pool.

  2. Click New Bandwidth Pool.

    The Add Bandwidth Pool dialog box opens.

  3. Make the following settings:

    Name: Enter a descriptive name for this bandwidth pool.

    Position: The position number, defining the priority of the bandwidth pool. Lower numbers have higher priority. Bandwidth pools are matched in ascending order. Once a bandwidth pool has matched, bandwidth pools with a higher number will not be evaluated anymore. Place the more specific pools at the top of the list to make sure that more vague pools match last. For example, if you have configured a traffic selector for web traffic (HTTP) in general and for web traffic to a particular host, place the bandwidth pool that uses the latter traffic selector on top of the bandwidth pool list, that is, select position 1 for it.

    Bandwidth: Enter the uplink bandwidth (in Kbit) you want to reserve for this bandwidth pool. For example, if you want to reserve 1 Mbit/s for a particular type of traffic, enter 1024.

    Note – You can only assign up to 90 % of the entire available bandwidth to a bandwidth pool. The gateway always reserves 10 % of the bandwidth for so-called unshaped traffic. To stay with the example above, if your uplink Internet connection is 5 Mbit/s and you want to assign as much bandwidth as possible to VoIP traffic, you can at most enter a value of 4608 Kbit/s.

    Specify upper bandwidth limit: The value you entered in the Bandwidth field above represents the guaranteed bandwidth to be reserved for a specific kind of traffic. However, a bandwidth pool usually allocates more bandwidth for its traffic if available. If you want a particular traffic not to consume more than a certain amount of your bandwidth, select this option to restrict the allocation of bandwidth to be used by this bandwidth pool to an upper limit.

    Traffic selectors: Select the traffic selectors you want to use for this bandwidth pool.

    Comment (optional): Add a description or other information.

  4. Click Save.

    The new bandwidth pool appears on the Bandwidth Pools list.

  5. Enable the rule.

    The new rule is disabled by default (toggle switch is gray). Click the toggle switch to enable the rule.The rule is now enabled (toggle switch is green).

To either edit or delete a bandwidth pool, click the corresponding buttons.
