Global Crossing wanted more visibility and control over its IP network like it had with legacy networks. It used Cisco MATE Design and collector to map its network and measure traffic flows. This allowed it to accurately simulate the network's behavior under different conditions and identify points of congestion. It could then optimize the network configuration and capacity planning to improve resilience and reliability while reducing costs. The MATE software helped Global Crossing transition from overprovisioning bandwidth to precisely targeting capacity increases only where needed.
