1.3.2 Cost optimization
Cost optimization mode decreases packet loss and improves the cost while not worsening latency more than allowed. If IRP cannot improve costs it tries to reduce latency. The platform runs the same algorithm for loss comparison as in performance optimization mode.
Figure 1.3.2: Cost optimization algorithm
Note that the diagram does not highlight higher cost cases. IRP operating in cost optimization mode can make improvements towards higher cost providers only when current routes suffer from loss.Before comparing latency values IRP compares the transit cost for each provider. If the cost of the new provider is better, the system goes further by checking the latency and validates the cost improvement only if the latency is not worsening more than predefined. However, if the cost cannot be improved, IRP tries to make a latency improvement using the same algorithm as in performance mode. Thus, if there is no way to make a cost improvement, system reroutes the traffic to the best performing provider.
