Fair Usage Policy (FUP)
Introduction
- From January 2023 RADIUSdesk now also includes a powerful FUP package.
- We worked with our clients to come up with a innovative and flexible implementation that packs a punch.
- This document will start with a high level discussion about the various FUP requirements met with this implementation.
- It will then go on to do a hands-on FUP profile.
- Finally we will show you where to tweak things should the need arise for your specific environment or implementation.
FUP Implementation
- In South Africa some of the big ISPs implement multiple layers of service for their FUP.
- There will be a reduction in bandwidth when a certain amount of data is used during the month.
- There will be a further reduction in bandwidth when a second milestone of data used is reached.
- Finally when a third milestone is reached the bandwidth is throttled down to a trickle.
- When the new month starts everything is reset back to normal speed again.
- Another requirement is the ability to assign an IP Pool to a certain level of service.
- This is typically with ISPs that use Mikrotik PPPoE servers.
- There will for instance be a premium IP Pool and a best effort IP Pool.
- A user will start off on the premium IP Pool up to the point where their specified FUP is triggered.
- Thereafter they are moved to the best effort IP Pool.
- Communities that uses RADIUSdesk wanted to offer their users more bandwidth between midnight and 7AM since the utilization on the up-link are very low during that time and it can then encourage a more distributed usage graph.
- With these various requirements in mind we formulated the FUP package in RADIUSdesk.
Hands-on FUP Profiles
- To configure the FUP part of a profile, go to RADIUS → Profiles.
- The edit option of a profile includes FUP.
- There are two sections for a FUP based profile.
- The first section specifies the basic speed when no limits are imposed.
- The second section contains a list of restriction FUP components to apply.
Basic Speed Limit - No limits imposed
FUP Components to apply
- In the screenshot above we see two stage throttling.
- When the user's total usage reached 100Gb we will half its bandwidth. (reduce to 50Mb/s)
- Then when the user reaches a usage of 200Gb we will reduce its bandwidth further. (reduce to 25Mb/s)
- The FUP component is composed of the following items.
- Descriptive name.
- If condition. Options include Time of day, Daily usage, Weekly usage, Monthly usage.
- For Time of day there will be a start time and end time.
- For data usage there will be an amount of data.
- Action. When the trigger has been reached we can block the traffic, decrease the speed or increase the speed.
- An optional IP Pool that should be used if the component is triggered.
- You can combine various type of FUP components together.
- The logic that applies them will use the following rules.
- Blocking traffic will take preference.
- Components that decrease the speed will use the slowest (biggest decrease percentage)
- Components that increase the speed will use the slowest (smallest increase percentage)
- This essentially means the strictest component's action will be applied.
