Software Defined Network Operations and Management Framework Over Multi-Domain Network Environment
One of the current Internet challenges is the demand of the open networking of which great advantage is to allow end users to innovate Internet based on programmable, virtualizing and federating network technologies. SDN (Software Defined Networking) with OpenFlow protocol is a major driver for the open networking, which has invoked significant interest in reconsidering traditional aspects of Internet architecture and design. Since SDN is closely coupled with the classical Internet (i.e. non-SDN), it is very important to keep the integrated network environment constantly reliable.
