"Roadmap to Operating SDN-based Networks" Workshop

Sponsors: ESnet, NSF, Internet2 and other LSN agencies

July 14-16, 2015

Berkeley, California



Background and Vision

This workshop is a follow-up to the first SDN workshop focused on SDN Operational issues sponsored by NITRD, DOE and NSF in December 2013. Since then, there has been great progress made, with a focus on SDNv2, Software-Defined Exchanges (SDX) and Software-Defined Infrastructure (SDI). Network operators and network researchers in the Federal agencies and R&E community have been experimenting extensively with SDN, through DOE-funded network research projects, through grants from NSF (e.g. GENI, CC-NIE, CC-IIE, and CC-DNI) and through multitude of testbeds.

Despite the number of use-cases and demonstrations showcased, as SDN is targeted towards production deployments targeting to replace current WAN networks, there are significant gaps to address. In addition, the hardware and software eco-system is not mature, leaving gaps for operators to address on their own. n addition, the SDN momentum has spawned multiple credible open-source projects, each with their own view of SDN, and driving the evolution of the implementation and design including protocol independent framework (PIF), Intent-based frameworks and use of NETCONF/YANG in addition to OpenFlow southbound interface.

The operational network gaps identified in the first workshop - manageability and security with a focus on supporting multi-tenancy and virtualised services have still not been addressed satisfactorily. In addition, the SDN momentum has spawned multiple credible open-source projects, each with their own view of SDN, and driving the evolution of the SDN design including protocol independent framework (PIF), Intent-based frameworks and use of NETCONF/YANG in addition to OpenFlow southbound interface.

The vision for this workshop is to bring together Academia, Industry, Government and R&E community into a dialogue of SDN reality today and desirable futures, with a focus on the Government and R&E community application requirements. The objective is to progress adoption of this new technology in the community, while incorporating innovative solutions to meet the application and operational challenges identified.

DOE, ESnet, Internet2, NITRD, NSF will be hosting and organising a follow-on to the operationalising SDN workshop on July 14 - 16th, 2015 at Lawrence Berkeley National Lab in Berkeley, CA.


Goal

Identify the challenges and opportunities to operationalize Software Defined Networks, Layer 1/2/3 Exchanges and Infrastructures (SDN/SDX/SDI) for research and education in the 2-3 year timeframe

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
