Large Scale Networking Coordinating Group (LSN CG)


The LSN CG coordinates the activities of the Large Scale Networking Program Component Area (PCA).

LSN members coordinate Federal agency networking R&D in leading-edge networking technologies, services, and enhanced performance, including programs in network security, new network architectures, dynamic multi-domain optical networking, heterogeneous networking (optical, mobile wireless, sensornet, IP,…), high data transport, federation across networking domains, testbeds, end-to-end performance measurement (e.g., development and use of perfSONAR), and advanced network components; grid, cloud, and collaboration networking tools and services; engineering, management, and use of large-scale networks for scientific and applications R&D, and research to address network complexity. The results of this coordinated R&D, once deployed, can help assure that the next generation of the Internet will be scalable, trustworthy, and flexible.

Operationalization of Software-Defined Networks (SDN) Program Review

Executive Summary

"U.S. federal investments in networking research and technologies deployment have fostered and accelerated the development of the Internet from its inception. It is now an essential infrastructure for the United States and the world. However, it is clear that we must make this infrastructure more flexible, resilient, secure, reliable, and ubiquitous to keep pace with society’s needs and our aspirations for the 21st century.

Recently, U.S. agencies have been investing in networking innovation that will lead to the next generation of communication and cloud technologies to provide improved capacity, tools, service, and equipment needed for applications to be supported by the future Internet. New application requirements like those of large workloads moving between data centers, massive number of devices participating in machine to machine communication, and high-bandwidth applications on mobile devices are forcing change in network architecture to be more responsive rather than statically provisioned. One of these future network technologies, Software-Defined Networking (SDN), has the potential and momentum to create new engines of innovation and transform the entire Internet ecosystem. In December 2013, an invited review on operationalizing SDN was conducted at the National Science Foundation (NSF) with representatives from the academic, federal, and commercial communities. Workshop sponsorship was provided by the Computer and Information Science and Engineering Directorate (CISE) of the NSF and the Advanced Scientific Computing Research (ASCR) Program of the Department of Energy Office of Science, with support from the National Coordination Office for Networking and Information Technology Research and Development (NCO for NITRD)....." read more
