This post describes steps to build an OpenFlow switch using Open vSwitch on a server running Ubuntu 18.0.4. The server runs a Ryu controller and Snort intrusion prevention system, both are open source software. Such a system could be used a security appliance in a network of low-to-medium bandwidth requirements.
Like many people, I have started learning about Software-Defined Networking and OpenFlow using Mininet, which is a great virtual environment to use. However, Mininet has some limitations, and I found myself looking for hardware alternatives. This article describes how to build an OpenFlow lab environment that can be used for… Read more »
The FlowManager is a RYU controller application that gives the user manual control over the flow tables in an OpenFlow network. The user can create, modify, or delete flows directly from the application. The user can also monitor the OpenFlow switches and view statistics. The FlowManager is ideal for learning… Read more »
The Zodiac WX from Northbound Networks is Dual-Band AC1200 AP that includes 2 Gigabit Ethernet ports and support for PoE. It also integrates Zodiac OpenFlow® engine with OpenWrt operating system. The Zodiac WX works with any standard OpenFlow® 1.3 compatible controller and appears to the controller as a 65-port Ethernet switch. This post explains how… Read more »
The Zodiac FX from Northbound Networks is an OpenFlow switch designed to deliver the power of Software Defined Networking to researchers, students, and anyone who wants to develop their SDN skills or build applications using real hardware. In a previous post, I described the process of connecting the Zodiac FX switch with… Read more »
Experimenting with Software Defined Networks (SDN) on real hardware has become a lot easier since I discovered the Zodiac FX switch from Northbound Networks. This 4-port switch supports Openflow v1.0 and v1.3, and it supports many Openflow controllers. This post describes the process of connecting the Zodiac FX switch with… Read more »
Software Defined Networks (SDN) is a new technology with a lot of potential and a healthy dose of hype. The main premise of SDN is moving the intelligence of the network from distributed network nodes to a centralized location to enable programmability and flexibility of configuration through software applications. Each… Read more »
