Session Abstract:"Open Networking" is a very popular industry initiative that aims to make networking equipment programmable and efficient while also lowering costs, especially OPEX. In this new paradigm, network operators may chose the software to control their networks- independent of their choice of networking hardware. There have been several architectures proposed to realize "Open Networking," including: Software Defined Networking (SDN)- with strict separation of data and control planes, Overlay models, Network Virtualization (& ETSI NFV), Linux based Network OS's -with embedded control plane software- running on bare metal switches, etc.
Representatives from three Open Networking vendors will address the topic from different perspectives.

Speaker: Guido Appenzeller

Bio: Guido Appenzeller, Ph.D. Co-founded Big Switch Networks Inc. in 2010 and has been its Chief Technology Officer since November 2013. Mr. Appenzeller served as Chief Executive Officer of Big Switch Networks Inc. until November 2013 and also served as its President. Mr. Appenzeller is an Entrepreneur-in-Residence at Morgenthaler. Guido received a Ph.D. in Computer Science from Stanford University in 2004.

Title: The Changing face of SDN

Abstract: Software Defined Networking (SDN) has emerged as e term to describe the biggest architectural change in networking systems over the past decade. At the core of this revolution is the idea that that network operators can chose what software they run to power their networks, and that this is independent of their choice of networking hardware. Originally, the term SDN described the separation of control and data planes, but since then its use has broadened to include overlay networks and bare metal switch software. In this talk, we try to give an overview of recent developments in SDN, describe architectures and use cases and give examples of recent production SDN deployments.

Speaker: Kenneth Duda

Bio: Kenneth Duda is a pioneer of advanced networking software and is the lead architect of Arista Networks EOS, a stateful modular operating system for all Arista Networks products. He is also co-author of VMware's VXLAN specification. From 2005 to 2008, Ken was also the Acting President of Arista Networks.
Prior to joining Arista Networks, Ken was the CTO at, where he played a lead role in designing a real-time 3-D distributed system that scaled to thousands of simultaneous users. Ken was also the first
employee of Granite Systems and led the software development effort for the Catalyst 4000 product line after the acquisition by Cisco.
Ken holds three engineering degrees from MIT and a Ph.D. in Computer Science from Stanford University.

Title: The Heart and Soul of a Linux-based Network Operating System

Abstract: The impact of Linux on the modern scale data center cannot be exaggerated. Linux provides the foundation of not only servers and storage, but networking as well. In this talk, I will compare three competing Linux-based network operating system architectures, focusing on their implications for reliability, extensibility, and SDN.

Speaker: Mat Mathews

Bio: Mat Mathews is Co-Founder & VP, Product Management, Plexxi Inc. Mat has more than 19 years of experience creating and executing product strategies for networking and network security companies and is currently leading Plexxi's product management and strategy efforts consisting of high-end data center switches, SDN-based control software, and open source hardware and software initiatives. Before Plexxi, Mat was VP of Product Management and Product Marketing at Arbor Networks, where he led all product portfolio management, strategic planning, and product line P&L for a $100m product portfolio and helped lead the company into data center security solutions. Danaher Corp acquired Arbor in August 2011. Prior to joining Arbor Networks, Mat was Vice President of Product Management at Crossbeam Systems where he was responsible for defining and launching all the company's products and helped drive Crossbeam into a market share leadership position for high-end security gateways. Before Crossbeam, Mat held several senior level Product Management positions at Convergent Networks, Xylan Communications and Bay Networks/Wellfleet Communications. Mat also co-founded and led the marketing efforts for a strategy consulting firm that helped legacy media and telecommunications companies build strategies to reinvent their businesses. Mat began his career as a software engineer for Wellfleet Communications, building high speed Frame Relay Switches for the carrier market. Mat holds a Bachelors of Science in Computer Systems Engineering from the University of Massachusetts at Amherst.

Title: The Heart of the Open Network

Abstract: Is policy, control and state Representation the basis for the Open Network? The industry has been obsessed with topics such as OpenFlow, overlay networking, and more recently debating what is Linuxxy enough for a network OS; yet Open Networking is pointless without access to data from the surrounding systems, and policy is meaningless without referencing those systems as well. In this talk we'll look at the spectrum of the application:network relationship from traditional heterogeneous environments to the modern homogeneous environments like Borg and Mesos and discuss how an open policy, control, and state representation layer actually opens the network to a multitude of workload types while employing a loosely coupled application:network relationship. This results in a vendor-transparent network that can implement the desired ephemeral and configured state, regardless of implementation rather than just an "open" network whose sole purpose is to be programmed.
