NEW COLLABORATIVE NSF GRANT: NETWORK INNOVATION THROUGH CHOICE

August 29, 2011

Our project on “Collaborative Research:Network Innovation Through Choice” has been funded by the National Science Foundation in the amount of $2.732M ($644K to NC State) for three years starting on September 15, 2011. This is a collaborative project among the University of Massachussets (Wolf and Nagurney), the University of Kentucky (Griffioen and Calvert), RENCI (Baldine), and NC State (Dutta, Rouskas).

Abstract:
Computer networks, in particular the Internet, represent essential infrastructure for business, government, military, and personal communication. Several recent trends in technology and network use have pushed the capabilities required of the Internet beyond what can be provided by the currently deployed infrastructure. To address these limitations, the network community has developed a variety of technologies to adapt the functionality of network protocols and services. A critical question that remains unanswered is how to integrate these technologies into an ecosystem that involves users, service providers, and developers in such a way that new ideas can be deployed and used in practice.

Market forces have had a drastic effect on the shape of services and applications at the edge of the network. Our research proposes a transformative shift in the design of networks that enables sustained innovation in the core of the network using economic principles. We believe that supporting choice is the key aspect of a network architecture that can adapt to emerging solutions for current and future challenges. Choice implies that users can select from alternatives that can be deployed dynamically into the network and reward those that address their needs. We use this interdependency between technological alternatives and economic incentives to create a competitive marketplace for innovative solutions that address current and future challenges in networking. Our proposed work describes fundamental research aimed at the design, development, and prototyping of aspects of a next-generation network architecture where such choices and competition drive innovation at all layers of the protocol stack.

The proposed network design is based on three tightly coupled principles. Our ChoiceNet system aims to (1) encourage alternatives to allow users to choose among a range of services, (2) let users vote with their wallet to reward superior and innovative services, (3) provide the mechanisms to stay informed on available alternatives and their performances. We propose a number of fundamental research problems that address the design of building blocks to provide alternatives in the network, the economic framework for incentives, the necessary monitoring and management components, and the prototyping, education, and outreach efforts. Overall, our work does not aim at reinventing technical solutions to networking problems, but at developing a comprehensive system where these solutions can be deployed and compete to allow the network to adapt to current and future challenges.

Intellectual Merit: Our project addresses one of the key problems in the current Internet – how to design a network that ensures long-term innovation inside the network core. The proposed research will provide solutions to fundamental questions on how to enable choice among different service alternatives, how to develop marketplace for incentive-based competition, and how to handle explicit control and management. The development of a prototype allows for realistic experimentation that includes community involvement and educational uses.

Broader Impact: Our project will contribute to enhancing the functionality and usability of the nextgeneration Internet, which will become an important piece of infrastructure. Our project also integrates research and education of graduate and undergraduate students at the participating organizations, where we will continue with our current involvement to integrate underrepresented minorities. Results from our work will be disseminated in the form of an open-source prototype and publications.

DEBUT IMPACT FACTOR FOR THE OSN JOURNAL

August 28, 2011

We are delighted to announce the first impact factor for the Optical Switching and Networking (OSN) Journal of an impressive 0.962 for 2010 (JCR® Thomson Reuters). There are 78 journals in the Telecommunications category, and OSN ranked 32nd, placing it in the second quartile. Considering the relatively small niche of optical networking that the Journal represents, this is a remarkable success. We owe our success to the quality of the published articles, the commitment of our Editorial Board and the skill of our reviewers. We are confident that our impact factor will continue to increase over the coming years.

The OSN Journal and the optical networking community also mourn the loss of Prof. Fabio Neri who served as co-Editor-in-Chief of the Journal since its inception. Fabio, a Professor at Politecnico of Torino, Italy, passed away in April 2011 at the young age of 53. The journal owes its success in large part to his dedication and tireless efforts over the last six years, and Fabio would have been happy to know about the impressive first impact factor that the Journal has received. Among all who knew Fabio professionally and personally, he will remain highly regarded for his work, generous service to the research community, and his sharp wit. His colleagues and friends will remember him as a brilliant, honest, direct, generous, and fun-loving person, who wanted to live his life to the fullest. Fabio will surely be missed.

You may submit your work to the OSN Journal.

NEW NSF GRANT ON OPTICAL NETWORK DESIGN

August 1, 2011

Our project on “Computationally Scalable Optical Network Design” has been funded by the National Science Foundation in the amount of $430K for three years starting on August 1, 2011.

Abstract:
Optical networking forms the foundation of the global network infrastructure, hence the planning and design of optical networks is crucial to the operation and economics of the Internet and its ability to support critical and reliable communication services. This research project aims to increase greatly our ability to solve optimally a range of optical design problems. In particular, the project will develop compact formulations and solution approaches that can be applied efficiently to instances encountered in Internet-scale environments. The ultimate goal is to lower the barrier to entry in fully exploring the solution space and in implementing and deploying innovative designs. The solutions to be developed are “future-proof” with respect to advances in dense wavelength division multiplexing (DWDM) transmission technology, as the size of the corresponding problem formulations is independent of the number of wavelengths.

Specific outcomes include: (a) computationally efficient formulations for the routing and wavelength assignment (RWA) problem, a subproblem of many design problems; (b) scalable optimal solutions to a suite of network design problems (including traffic grooming, survivability, and impairment-aware routing) that can be applied to topologies encountered in practice; (c) investigation and characterization of limiting solutions and technology tradeoffs in the “large W” regime that is consistent with DWDM technology trends; (d) benchmarking of existing heuristics and development of new polynomial-time algorithms that leverage the structure of optimal solutions; and (e) a set of integrated community building, research collaboration, and technology transfer activities that engage a wide range of students, including underrepresented groups in computer science.

Broader Impact: The project will develop new capabilities for the design and operation of optical networks that form the backbone of the Internet infrastructure. The proposed framework with its emphasis on scaling optimal solutions to networks of realistic size will open new directions for network design by permitting extensive “what-if” analysis to explore the sensitivity of design decisions to forecast traffic demands, capital and operational cost assumptions, service price structures, etc. The research agenda has the potential enable a wide range of 21st century science, education, and commercial applications through the design of networks that are better optimized for user and application requirements and are less expensive to build and operate.
