Push Customer Tariff Speeds to ONT / CPE Devices

We would like Splynx to support pushing customer tariff upload and download speeds directly to customer access equipment, such as:

• Fibre ONT / ONU

• Wireless CPE dish

Many ISPs and FNOs use Splynx to manage customer packages, but the actual speed limit often also needs to be applied at the customer access device. This is especially important where the FNO manages the access network and hands traffic over to an ISP for breakout.

The requested feature is for Splynx to automatically push the customer’s tariff speed to the linked ONT/ONU or wireless CPE when:

• A customer is activated

• A package is upgraded or downgraded

• A customer is suspended or reactivated

• A service is changed

This could be done through UISP integration or another device/API integration method.

Splynx should also allow a user-defined margin above the tariff speed, for example 10%, when pushing the limit to the ONT/CPE. This allows the ONT/CPE to act as a safety limit, while the ISP can still use its main router or optimisation platform for proper QoE shaping such as FQ-CoDel, CAKE, or other shaping methods.

Why this is important

If speed limits are only applied at the main router, access router, or central traffic shaper, some traffic may already have crossed the last-mile network, wireless sector, PON, repeater link, backhaul, or internal ISP network before being shaped.

This can cause:

• Customer devices uploading or downloading at full port speed before reaching the shaper

• DDoS attacks or infected devices using the full ONT/CPE upload capacity

• Congestion on the last mile, PON, wireless sector, repeater link, or backhaul

• Other customers on the same access network being affected

• Local/on-net traffic bypassing the central shaper and running at full port speed

• Customers using more than their package speed when local/on-net traffic and internet traffic are combined

For example, a business customer may view live CCTV from home over the same ISP network. This traffic may route internally and never pass through the central shaper. The customer may then receive CCTV traffic at full port speed while still receiving their full internet package speed, resulting in total usage above the package they are paying for.

Example

If a customer is on a 20Mbps package, Splynx should be able to push a 20Mbps limit to the ONT/CPE, or push 22Mbps if the ISP sets a 10% margin.

This would be useful for ISPs/FNOs using Splynx with Ubiquiti fibre and wireless networks, and for any provider that needs customer speeds enforced at the access-device level before traffic reaches the core router or central traffic shaper.
