Build your audience tree

The Quortex Switch audience tree determines which CDN each defined audience segment is routed to. To build this tree, you need to add sub-segments that refine your audience definitions.

You can create these sub-segments using either the UI or the API.

Available Segment Types

Quortex Switch supports four types of audience segmentation:

• 🌍 Geolocation
• 🌐 Network (ASN)
• 📱 Device Type
• 🔁 Streaming Protocol (HLS or DASH)

Each segment can have its own CDN prioritization and balancing strategy.

Geolocation-Based Segment

This segment defines the audience based on user location, using a list of regions (e.g., Europe, Asia-Pacific) and/or countries.

✅ Recommended use: when CDN performance or pricing varies by region.

📌 Notes:

• Multiple geo segments can be chained or parallelized to refine targeting.
• Geo segments must be added before all other segment types.

Network-Based Segment (ASN)

This segment targets users based on the network they are connected to, identified by their ASN.

✅ Recommended use: to optimize CDN delivery for specific ISPs or network providers.

📌 Notes:

• You can add multiple ASNs to a segment.
• A network segment can be added in a parallel branch, but not as a sub-segment of another network segment.
• If added under a geo segment, the available ASNs will be filtered based on the selected region.

Device Type Segment

This segment targets users based on the device they are using (e.g., desktop, mobile, smart TV, Android).

✅ Recommended use: when a CDN is optimized for specific devices (e.g., 4K delivery to TVs) or has limitations with certain platforms.

📌 Notes:

• Device segments can be added in parallel branches, but not as sub-segments of other device segments.

Protocol-Based Segment

This segment splits the audience based on the streaming protocol used: HLS or DASH.

✅ Recommended use: when a CDN supports only one protocol or performs better with a specific one.

📌 Notes:

• Since there are only two protocols, both branches are automatically created to split the audience accordingly.
