Intelligent Network Control Enables On-The-Fly Detours Around Problems

Achievement date: 

A new control and management software system (CMS) uses dynamic decision-making to route messages intelligently on optical networks. The CMS features several new functionalities demonstrated by researchers at the Center for Integrated Access Networks (CIAN), an NSF-funded Engineering Research Center (ERC) based at the University of Arizona.


Smarter network controls can help meet the rising demands on network applications, including those sensitive to any delays, such as multiplayer gaming and high-frequency stock trading and those demanding fast throughput, such as HD video streaming and electronic health care.


The new CMS introduces cross-layer optimization and enables a network to reconfigure itself based on changing situations. A team led by UA’s June He and John Wissinger in collaboration with Craig Healy of Fujitsu Network Communications, one of CIAN’s industry partners, developed the new CMS .

Demonstrated in the CIAN Testbed of Optical Aggregation Network (TOAN), the experimental results show significant reduction from hours to several seconds in the time it took to restore network service and in detecting and recovering network failure (e.g., fiber disconnection).
