Software Defined Network, Openflow Protocol and its Controllers

Recently Software Defined Network (SDN) technology has become important and openflow is focused on as basic building block of SDN. Those technologies are important for creating test bed for experimental protocol by standardizing protocol to manage switches and production use to reduce maintenance cost of network by automation via software as network virtualization. As they are emerging technology, the development of software to use openflow is hot area. In this presentation, I review SDN, openflow and openvswitch which is opensource software implementation of openflow. And then survey openflow controllers describing their features and goal. The target audience is those who would like to take overview of those technology. No deep knowledge is required.

Isaku Yamahata, VA Linux Systems Japan K.K.

Isaku Yamahata has been working on virtualization development for more than past 6 years for VA Linux Systems Japan K.K. He has contributed greatly to qemu, kvm and xen community. His major contribution to Linux is pv_ops and xen support to Linux especially ia64/pv_ops/xen support. His current main interest is to improve qemu, kvm and cloud-related technology and has been working on opensatck, openvswtich and openflow recently.

Ryu Network Operating System

Ryu is an open-sourced Network Operating System (NOS) licensed under GPL v3. Ryu aims to provide a logically centralized control and well defined API that make it easy for operators to create new network management and control applications. Currently, Ryu supports OpenFlow protocol to modify the behavior of network devices. The project goal is to develop an OSS Network Operating System that has high quality enough for use in large production environment in code quality/functionality/usability. We aim at the de facto OSS NOS implementation and NOS API. This talk is intended for system administrators and developers. Audience members will learn Ryu design and how to manage network with Ryu. We expect that the audience is familiar with network.

Kazutaka Morita, NTT

Kazutaka Morita is a research developer working for Open Source Software Computing Group at NTT Labs. His group has been developing open source software such as TGT (SCSI target framework), NILFS (log structured file system) and Sheepdog (distributed storage system for QEMU). He has been working on distributed storage systems such as Lustre, GlusterFS and Ceph, and is the maintainer of Sheepdog storage system.
