Inter-working between SDN controllers as an OpenDaylight application

Background and motivation

It is time for reality check on SDN. See this: "SDN hits rock bottom and FCoE is obsolete, say Gartner mages"

From my experiences in the area of SDN, I conclude that SDN is just about software architecture and engineering optimized for each use case, and there is no one-fits-all SDN controller or platform. From now on, we had better focus on good-quality open source software components and integrating them into a purpose-built system on PaaS.

Let's think about using OpenDaylight MD-SAL as a device driver for your SDN controller or vise versa.

Chapter 1: Learning OpenDaylight MD-SAL

First, you need to learn how to write your application on OpenDaylight.

Read this and write a hello app: HOW-TO-WRITE-YOUR-ODL-APP

Chapter 2: Architecture discussion

Architecture discussion for inter-working with your SDN controller: ARCHITECTURE

Chapter 3: Sample implementation

I use Hazelcast for this sample implementation: SYNC-WITH-HAZELCAST

Homework

This is the end of DIY on MD-SAL, and it is time to review what you have done: HOMEWORK
