## What is OpenMUL ?

Open Mul is an Openflow / SDN controller platform. It has a C language 
based multi-threaded infrastructure at its core. It supports a multi-level 
north bound interface for hosting applications. It aims to support various 
SDN enabling south-bound protocols such as Openflow 1.4, 1.3 and 1.0 along 
with ovsdb, of-config etc.

It is designed for performance and reliability which is the need of the hour 
for deployment in mission-critical networks. It is also highly flexible, 
modular and easy to learn.
