Quortex Switch offers two ways to distribute traffic across your CDNs. The choice depends on your goals—whether you want to optimize for cost, performance, or peak/off-peak flexibility. You can select the balancing type for each segment you create.

1. Percentage-Based Balancing

This method splits traffic between selected CDNs based on predefined percentages.

How it works:

Each CDN is assigned a percentage. The content steering server uses these values to prioritize traffic distribution.

Why choose this:

Easy to adjust if issues occur.

Ideal for cost optimization:

• Use the cheapest CDN during off-peak periods.
• Add more CDNs during peak traffic for better performance.

Best practice:

Always configure a backup CDN with 0% traffic. It won’t be used unless another CDN fails, ensuring service continuity.

Example configuration:

• CDN A: 60%
• CDN B: 40%
• CDN C (backup): 0%

2. Capacity-Based Balancing

This method works like a waterfall and prioritizes CDNs based on their maximum capacity.

How it works:

The first CDN handles traffic until it reaches its defined capacity (in Gbps).

• Once full, traffic flows to the next CDN, and so on.
• The last CDN acts as a backup if all others are saturated.

Why choose this:

Perfect for performance-driven setups.

• Ensures predictable load distribution based on CDN limits.

Example configuration:

• CDN A: 50 Gbps
• CDN B: 30 Gbps
• CDN C (backup): unlimited

Tip: You can mix strategies across segments to adapt to traffic patterns and business priorities.
