- You configure each property with a traffic weight per data center. For example, for an even split between two data centers you might give each data center a weight of 1. Global Traffic Management normalizes the two weights, splitting them evenly (0.5 and 0.5) across the data centers so they total 1.
- Global Traffic Management collects the load information (either from load objects or from liveness test download scores) and sums the load across all data centers for a property. It then multiplies this sum by the load imbalance factor to get a total target load and computes each data center's target by multiplying the total target by the data center's normalized weight.
- The total load is 5.
- The total target load is 6.25 (5 * 1.25).
- The target load for each data center is 3.125 (half of 6.25).
This puts data center B over its target load and data center A under its target load, so Global Traffic Management attempts to shift some traffic from data center B to data center A.
If you configure your property for Performance-Based Load Balancing with Load Feedback Based on Liveness Test Download Scores or Performance-Based Load Balancing with Load Feedback (targets computed from configured weights) , the computed-targets flag for your property is set automatically.
