In this tutorial you will learn to write a distributed ONOS application. The application you will be writing is called BYON (Bring Build Your Own Network). This tutorial will teach you how to implement an ONOS service, an ONOS store (both trivial and distributed) and how to use parts of the CLI and Northbound API. First, you will start with a single instance implementation which will be fully functional. After this, you will implement a distributed implementation of the service. The idea here will be for you to see how simple transitioning from a trivial single instance implementation to a distributed implementation is. Believe it or not, most of your code does not change.

At this point, you multi-instance ONOS deployment is functional. Let's move on to writing some code.

Build Your Own Network'
We are now going to start building BYON. BYON is a service which allows you to spawn virtual networks in which each host is connected to every other host of that virtual network. Basically, each virtual network contains a full mesh of the hosts that make it up.
