Transmission resilience targets at optimal resource utilization are secured by Netonomics' novel approach to traffic engineering. Fiber and IP routing investment to reach required targts for backbone and access is minimized by designing optimized topology and capacity. Netonomics’ methods are based on system optimization and thorough practical experience. Tailoring to the situation on the ground secures operational gains and savings. Control already at the planning stage of the targets and effects of the transmission design is another benefit. References with global top operators include optimization of backbone, backhaul, and C-RAN pooling with link design.
