Design and Implementation of Real-Time Flow Viewer across Different Domains

Due to rapid development of Internet, the amount of users around the globe is fast-growing in the past 30 years. It leads to the appearance of many problems, such as lack of IPaddresses, worse quality of service, and so on. In order to resolve these problems, many researchers start to design and implement innovative network architectures, which we call Future Internet. Most Future Internet projects in the world deploy OpenFlow technology developed by Stanford University in current network backbone to setup programmable Future Internet test beds. Currently, many international experiments have at least one controller for each organization in order to decrease overheads in single controller environment. In this paper, we study and implement real-time flow viewer across different domains based on the automatic network topology discovery system from our previous work. The real-time flow viewer can be used as a network management tool for validation of inter-domain flow assignment and observation of network activities across different domains.
