About predefined shaping policies
The Bandwidth module comes with predefined policies. The predefined policies listed are defined according to function and can be altered to suit your own operational needs. However, you can create policies based on a single application, single application group, or a mixture to suit a subnet. For example, a school might create a policy, which lists all individual applications that need to have restricted bandwidth, which accessed from a classroom, and an additional policy that has less restrictive bandwidth for the same applications when accessed from a recreational area.
| Policy | Description |
|---|---|
| Business |
The Business policy defines bandwidth application slices and caps for the following services relevant for a corporate environment:
This configuration gives priority to home working services. If there's excessive demand, Collaboration services receive half the allocation of Remote Access services, and Mail services receive half again. The Mail services slice is smaller as email packets tend to be small and non-interactive. All other services receive the same priority as home working services. |
| Control video streaming |
This policy defines bandwidth application slices and caps for the following services typically relevant for a video streaming environment:
This configuration gives priority to all other traffic. If there's excessive demand on bandwidth, named video streaming services receive one tenth of the available bandwidth compared to all others. |
| Default | This is the “catch-all” policy for those services that aren't allocated to another bandwidth shaping policy. All traffic is treated fairly. |
| Limit file sharing |
This policy defines bandwidth application slices and caps for services relevant for peer-to-peer file sharing:
This configuration gives priority to all other traffic. File transfer services receive one tenth of the available bandwidth compared to all others but are capped at 32 kilobits per second. |
| Slow video streaming |
This configuration caps available bandwidth for the specified services so that they're slow all the time. |
| Video conference |
This policy reserves up to 90% of allocated bandwidth for video conferencing. Desktop sharing is also included in this policy. The following services are defined:
This configuration gives priority to all listed. |
| Voice over IP |
This policy defines bandwidth application slices and caps for the following VoIP protocols:
If there's excessive demand on bandwidth, this configuration provides a dedicated slice of bandwidth to specified services to avoid VoIP latency. |
