I have been working on SDN applications for quite some time now and wanted to create a demo/sample app that could be reference or bootstrap app for people willing to explore more.
So I took some time out to come up with a idea of doing a very basic (some might call it no-brainer) SDN app for learning.
This application helps demonstrate following:
- Demonstrate how REST API’s of a SDN Controller (in my case OpenDaylight) can be used to build a app.
- I did not want to use any server-side programming/code to do this. This really shows the power of REST & SDN architecture.
- Simple app that is easy to understand and replicate for someone learning this stuff.
- Help you understand some concepts of SDN NBI that people talk about.
What is Network Statistics SDN Application ?
Bundled into a beautiful GUI, Network Statistics SDN Application runs on-top of a OpenDaylight SDN Controller and tracks port & table statistics of devices/nodes managed via OpenDaylight SDN Controller. Pure jQuery/Bootstrap and HTML based application without any server-side code.
Complete set of UI Screens developed for the application.
Things you can do in this application:
- Supply the URL/Username/Password of your OpenDaylight SDN Controller. Start tracking Nodes!
- View all the nodes managed by OpenDaylight in Network Devices section.
- View Port and Table statistics of each node found.
This is kind of no-brainier, but you can come up with more use cases around it etc, what this app if for? Its just for the kick-start.
If you are interested in running it:
- You can get the complete code from my git or if that’s too much work and you don’t intend to change code & just want to see it in action, download the file of this application from here (do “Save Link As“, this is .png, rename it to .war).
- Run the application either from code or by dropping the .war into tomcat/jetty/jboss (some web server)
- Supply your pre-installed OpenDaylight credentials and see it in action at http://localhost:8080/NetworkStatsApplication/
- I assume that you have a mininet and OpenDaylight setup working already as that is a per-requisite to building any application.
- I prefer you read Brent’s blog on this which I refer whenever I’m stuck at things he has written about.
