November 2015: Software Defined Networking (SDN) for Scientific Networking Workshop, Austin, Texas

Software Defined Networking (SDN) is an emerging technology that decouples the network control plane from the actual data which flows across the network on the data plane. By doing so, SDN introduces the concept of programmability into the network, allowing application owners and network operators to customize network software to meet their needs.

SDN has gone beyond the phase of simply being an exciting and novel technology for network operators. Large commercial ISP’s are already capitalizing on the benefits on SDN, which enables them to run their networks at close to 100% capacity. The Research and Education community has deployed it experimentally on their network backbones. Campuses are exploring its use in order for scientists to route high throughput traffic around the campus LAN and closer to the network backbone where it will get sent to their collaborators.

However, much discussion is still needed around standardized SDN technical architectures. SDN enables the use of multiple forms of controller software, most of which lack interoperability. Due to the lack of standards, SDN is often used in “islands” – within a campus or internal to a data center, but rarely between campuses. This leaves the promise of SDN’s benefits unrealized. Most campuses which support distributed, high speed links and scientific research have implemented a ScienceDMZ, a standardized technical architecture. This workshop intends to explore a similar path to creating a standardized technical architecture for SDN, including discussion of a standardized point at which to exchange traffic, called an SDN Exchange, or SDX.

While industry partners and collaborative network engineers can create solutions, the input from those who conduct the science is crucial because it’s their workflow which must be supported by a network. A still unexplored question is which scientific disciplines can benefit the most from an SDN optimized network? The workshop will also explore this question.


Call for papers



Workshop on SDN for Scientific Networking

in conjunction with SC’15

Nov 20th, 2015 – Austin, Tx

Submission Deadline: August 31, 2015




Call for Papers – SDN for Scientific Networking


Join us for a special workshop “SDN for Scientific Networking”, a technical half-day workshop held in conjunction with SuperComputing’15, that brings together domain scientists, HPC experts, network operators and security practitioners for a discussion of the current state of Software Defined Networking (SDN). With participants from campuses, academia, research, industry, and government, this workshop will discuss current and proposed uses for SDN in scientific communities. This workshop will explore the use of SDN for network optimization, address the security challenges with SDN and discuss emerging SDN architectures. The paper panels and lightning talks will focus on innovative SDN use cases either planned or in production.


Topics of interest include (but are not limited to):

o   Data workflows - SDN’s Value for Data Stage-In, Stage Out

o   New security considerations and challenges with SDN (e.g., protecting the controller, dealing with complexity and new dynamics)

o   SDN for Integration of on site and cloud jobs

o   SDN for Multi tenancy

o   SDN use cases within Scientific Disciplines such as climate change, genomics, and others

o   SDN to enhance the security of the Science DMZ or solve security challenges in new ways (e.g., SDN-based firewalls)

o   SDN within the HPC Data Center

o   QoS guarantees and SDN for real-time science (e.g., getting large volumes of instrument data offsite in real time)

o   SDN for Distributed Science DMZs

o   SDN for interconnecting Science DMZs or HPC centers

o   Fabrics based on SDN switches and cluster schedulers that are either aware of cluster topology or can control the topology

Paper Submission
The workshop solicits outstanding original research and practice papers as well as architectural designs on all aspects of SDN for scientific computing. Papers should clearly demonstrate the research or practical contribution and the relevance to scientific computing. Submitted papers will be reviewed by at least three members of the planning committee. Full papers are not to exceed 10 pages including all references and figures. Shorter papers (no minimum length) are highly encouraged for the lightning talks. We also welcome case studies and proposed architectural designs. If you're submitting a paper or lightning talk, please anticipate attending this workshop or sending a representative to present for you.


Paper submissions are managed electronically through the EasyChair Website:
