“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 paradagm, 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.
The Changing face of SDN
Big Switch will present an overview of recent developments in SDN, describe architectures and use cases and give examples of recent production SDN deployment models.  Software Defined Networking (SDN) has emerged as the 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.
The Heart and Soul of a Linux-based Network Operating System
Arista Networks will higlight the benefits of a Linux-based network OS, including “closed Linux”, “Bare linux”, and “Open Linux.”  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.

Plexxi will describe an open policy control and state implementation facilitating true open networking (more than just “programming” network equipment). 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.
