Advanced Optical Networks
With its research partners, iCAIR designs and develops new architecture, services, and technologies related to next generation networks based on advanced optical technologies, including those that are based on dynamic lightpath provisioning. iCAIR has established multiple initiatives with these partners to implement these innovations on prototype networks and early production networks, regionally, nationally, and globally.
New services based on advanced optical networks allow routed packet services to be complemented by integrated L1 and L2 services. The term “hybrid networks” is used to describe these multi-layer integrated capabilities. The primary facilities and networks that are advancing the innovations in next generation optical networking are described here. Key issues include the architecture and design for an optimized large-scale, reliable networking infrastructure based on advanced optical networking technology.
New types of architectures envision extremely powerful high-capacity network cores, with complexity and network intelligence pushed to the edge. These directions include migrating from networks based on multiple hierarchical levels to simpler, more flexible designs that allow for faster service provisioning, optimized transit, enhanced reliability, and customization opportunities. These designs incorporate new types of control planes, and dynamic, intelligent optical core components.
StarLightSM, the "optical STAR TAP" (Science, Technology and Research Transit Access Point), is a National Science Foundation-funded international communications exchange facility on Northwestern’s Chicago campus, which interconnects advanced networks world-wide. STAR TAPSM, was the first international interconnection point that had facilitated the long-term interconnection and interoperability of advanced international networking since 1997. StarLight, its successor has been designed and developed "researchers, for researchers," specifically by the Electronic Visualization Laboratory of UIC (EVL), the International Center for Advanced Internet Research (iCAIR) at Northwestern University, and the Mathematics and Computer Science Division at Argonne National Laboratory, in partnership with Canada's CANARIE and Holland's SURFnet. The global scientist community were among the first users of this facility because of the requirements of their data intensive applications as well as their need for distributed computing and storage. Currently, StarLight supports science research communities world-wide. This facility is also being used as an experimental proving ground for next generation emerging national and international optical networks, that are laying the groundwork for future optical networks and network services optimized for high-performance applications. StarLight is a core resource for the international Global Lambda Integrated Facility (GLIF), a world-wide optical fiber based resource that enables multiple advanced applications and networks to be designed and implemented. StarLight is one of the GLIF Open Lambda Exchanges (GOLEs) /StarLight
