Traffic Shaping

Manage your bandwidth by assigning rules to the bandwidth queues that you have created, thus limiting the speeds at which certain IP ranges, identities or blacklists can access internet resources and capping these off by setting up ceiling limits.

VoIP has now also been prioritized and by dedicating a specific upload and download throughput to it; this will ensure that there is no interference with the VoIP traffic should your connection becom highly saturated with data traffic. We have also addressed the issue of data packets interfering with VoIP packets by prioritizing the VoIP traffic in this way.

11.1 Configuration

WAN Capacity

  • Enable Traffic Shaping
  • Enter WAN Download Throughput (Connectivity download speed)
  • Enter WAN Upload Throughput (Connectivity upload speed)

Dedicated VoIP Capacity

  • Enable VoIP dequeing and prioritisation. (this will reserve throughput for VoIP Traffic and keep it separate from your Data Traffic).
  • VoIP Bypass DPI Engine (not recommended, Bypassing the DPI engine for voice traffic could allow for better quality VoIP calls, however traffic will not be accounted for or protected.)
  • Set your VoIP Download Throughput
  • Set your VoIP Upload Throughput

11.2 Queues / Allocation / Rules

Download Queues

Adding your download queues, select the + Add Download Queue radio button to setup and add a download Queue.

  • Name: name your queue according to the the traffic you want to add i.e dl-mail
  • Rate (promised): enter your promised rate required, you can select Kbps or Mbps. This will ensure that the amount set here will always be available.
  • Ceiling rate: enter the ceiling rate that can be used if available. This will be the maximum rate that it can use should it be available.
  • Priority: select the priority that this queue adhere to, scale from 1 to 10, 1 being critical, 5 normal and 10 less critical.
  • SQF: Stochastic Fairness Queueing (fair queue sharing) prevents a single stream from being able to use the entire queue. Recommended for a highly constrained WAN connection and requires fair sharing. (Not recommended for low latency requirements).

Once you have added your selections, select the Add Download Queue radio button to add it to the Queue list.

Upload Queues

Adding your upload queues, select the + Add Upload Queue radio button.

  • Follow the same steps as you did to add the download queue.

Traffic Allocation Rules

Adding traffic allocation rules, select the + Add Traffic Tagging Rule radio button. This allows you to select the Rule Type and allocate the Download and Upload Queues you created and place the rule in order of priority.

Adding a new Traffice Tagging Rule.

  • Rule Type: select you rule type from the drop down list.
  • - URL Group (this will allow you to select the URL Group that you created in your Policies Section)
  • - Blacklists (this allows you to select a blacklist category from the predefined blacklists)
  • - IP Rule (many options are available for this rule type, Inbound Interface, Source: MAC address, Identity, Policy and IP Address or IP Range. Different Protocols can be selected.
  • Download Queues: Select your download queue from the drop down list you created earlier.
  • Upload Queues: Select your upload queue from the drop down list you created earlier.

Once you have made your selections select the Add Rule radio button to add the rule.
