Routing Optimization is the process of determining the most efficient paths for data, goods, or vehicles to travel across a network. Algorithms balance factors such as distance, cost, congestion, and reliability. In telecommunications, it minimizes latency and improves network throughput. Mathematical models like Dijkstra’s and Bellman-Ford algorithms serve as foundational techniques. Advances in AI have led to adaptive routing systems capable of real-time decision-making.
We report the first trial of network tomography over a live network in a multi-domain environment. We visualize end-to-end optical powers along multiple routes across multiple domains solely from a commercial B00G transponder, enabling performance bottleneck localization, power and routing optimization, and lightpath provisioning.
