It is surprising to note that most of the other projects are heavily vendor driven but we are delivering all of this with a passion driven approach to solve real-life problems.
The major problem with legacy network equipment which spawned the SDN
movement has been the lack of simple and centralized management plane all the
while making the network highly agile. Various legacy devices like IP routers
had different and proprietary control plane to data plane interfaces and hence it
became impossible to centralize the control plane. Even the north bound
interfaces on top of control planes like SNMP, netconf varied wildly for each
One of the major USP of Openflow has been standardized interface between
control and data plane. It gives us immense potential to centralize control planes
and provide centralized control to network operators.
Having such a separation is great but is it a good idea to reinvent the way
networks all around the world have been designed?
The simple answer-we don’t need to redesign the networks. Because networks
still need to talk, say, OSPFv2 or BGPv4. These are built into DNA of modern
network infrastructure. But, Openflow can be definitely be used to solve the
centralized management problems. Effort should be put to bring more devices
under centralized management umbrella while letting interface to the external
world unchanged i.e. use OSPF, BGP etc as is.

The open-source code will be available in upcoming release of OpenMul ‘Concave’ in Jan 2015.
Many SDN enthusiasts ask us what sets us apart from other bigger projects like Opendaylight. ODL is a great project no doubt and has many features but we feel ODL is not yet ready for prime time and its architecture is inherently prone to stability and performance problems related to switch and application handling. On a highly loaded and dynamic network, stability and performance are of prime importance and that is where Openmul delivers and wins. Check Openmul Vs ODL performance and find out more.
Apart from performance the major points which sets openmul apart from the competition:
