## 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. ## How to get openmul source-code ? $ git clone https://github.com/openmul/openmul.git For getting source code based on permissive license (eg Apache or BSD) or any support, please contact support@openmul.org ## How to build MUL Controller on Ubuntu/CentOS ? 1. Run all-in-one build command : a) For Ubuntu 12.04 LTS/CentOS-5 or higher, run the following command : $ ./build.sh The above command will install all necessary packages and build necessary modules. b) For using the GUI, follow the INSTALL.GUI readme file 2. Executables will be built as : Core : <top-mul-dir>/mul/mul Application (eg l2switch) : <top-mul-dir>/application/l2switch/mull2sw - Other applications will be built in their respective directories inside <top-mul-dir>/application/ - You need to run using sudo or as admin. 6. How to run ? Mul provides an utility startup script for various use cases : 1. Initialize MuL's execution environment 2. Start MuL and its components $ cd <top-mul-dir> $ ./mul.sh start l2switch ## Run in l2switch mode OR, $ ./mul.sh start fabric ## Run in fabric OR, $ ./mul.sh -h ## Show all options 7. Please follow openmul documentation in <top-mul-dir>/docs 8. For further information please visit www.openmul.org
