Technical Program


Software Defined Networking (SDN) refactors the relationship between network devices and the software that controls them. Open interfaces to network switches enable more flexible and predictable network control, and they make it easier to extend network function. During the past few years, several router vendors have introduced software development kits for programming their network devices, and several commercial switches now support the emerging OpenFlow standard. Researchers have proposed new applications that can run on top of a software defined network, including dynamic access control, server load balancing, energy-efficient networking, and seamless client mobility and virtual-machine migration. Many research and industry groups worldwide are pursuing different aspects of software defined networking, and experimental and production deployments exist.

Still, many important research challenges remain: how to design switches and APIs that offer greater flexibility without compromising performance; how to design a software platform for the control and management of software defined networks; how to design new applications that capitalize on the programmability of the network; how to lower the barrier to creating, testing, and evaluating new applications; how to transition an existing network to SDN, and how a software defined network can interoperate with existing protocols and devices; and many others.

The goal of the workshop is to explore recent research and developments related to SDN; to allow an exchange of ideas; to encourage broad interaction between industry and academia; and to help build a wider community to explore and realize the potential of SDN.

We encourage submission of both position papers and work-in-progress papers on previously unpublished work on Software Defined Networking.


We solicit submissions on topics including, but not limited to, the following:

  • Applications of SDN in home, wireless, cellular, enterprise, data-center, and backbone networks
  • Application of SDN to network management, performance monitoring, security, etc.
  • Virtual appliances (e.g., firewalls, intrusion detection systems, load balancers, etc.) on SDN
  • Virtualization support in software-defined networks
  • Switch designs for SDN
  • Application Programming Interfaces for SDN
  • Control and management software stack for SDN
  • Programming languages, verification techniques, and tools for SDN
  • Performance evaluation of SDN network elements and controllers
  • Experiences deploying SDN technology and applications in operational networks
  • Hybrid SDN approaches (integration with other control planes)
  • Transitioning existing networks to SDN
  • Placement and factoring of SDN control logic

Submission Instructions

Each submission must be a single PDF file no longer than six (6) pages in length (in two-column, 10-point format) including references, following the LaTeX style file. Papers should be submitted via the submission site. Papers must include the author name and affiliation for single-blind peer reviewing by the program committee. Authors of accepted papers are expected to present their papers at the workshop.
