Using Custom Prioritization Rules in QoS

Bigleaf's dynamic Quality of Service (QoS) system provides effective and automatic prioritization for traffic traversing the public internet. Bigleaf uses unique technology to provide QoS without coordination of the network devices between the endpoints.

About Custom Prioritization Rules 

Bigleaf can configure custom prioritization rules for upload traffic at your site on our Bigleaf routers, and download traffic from the Bigleaf Gateway Clusters servers in our Points of Presence (POPs). The three most common use cases for custom rules are:

Increase priority of a business-critical application

Give priority to your most important applications. For example, web traffic to Office 365 is typically classified as Bulk Data or Interactive, but we can create a custom prioritization rule to make this type of traffic Urgent, giving it high priority. 

Unclear Protocol classification

SSL-VPN on TCP 443 could be classified as Bulk Data, so we can manually classify it as Interactive or Urgent class.

Custom applications using non-standard ports and protocols

If you set custom ports for your application, such as a web server on TCP 8843, or SIP signaling protocol for VoIP on TCP 6060, there’s a possibility it could be incorrectly classified. We can classify traffic as needed for your custom ports.

Example use case

If you are reviewing the Throughput charts on the Performance page in Bigleaf Cloud Connect, and you notice a large amount of ‘Other’ classified traffic, it’s likely an application is not classified properly. This may cause performance issues.

The example below shows a significant percentage of throughput on a circuit indicated as Other. A custom prioritization rule can classify this traffic accordingly and set the proper priority.

Creating Custom Prioritization Rules

If you’d like to use custom prioritization rules, contact Bigleaf Support. We can help you determine how an application or service is being classified, and create a custom rule if necessary.
