Welcome to "Hello Trema!"

The "Hello Trema!" example is one of the simplest OpenFlow controller implementations. The basic functionality of this controller is to establish an OpenFlow channel connection with an OpenFlow switch and output the "Hello 0xabc! (switch's datapath ID)" message.

This example demonstrates a minimum template for Trema applications written in Ruby. Hence, it's a good starting point to learn about Trema programming.

Prerequisites
