Automatical End to End Topology Discovery and Flow Viewer on SDN

Abstract

Recently, the Future Internet technology becomes a popular research topic. To solve the problems caused in traditional network, most researchers propose various new network architectures. One of the famous architectures is Software-defined network (SDN), which can help users develop their own strategies freely without the limited functions on physical machines provided by specific venders. One of the famous software that realizes the concepts of SDN is Open Flow. It is very important to manage and maintain an Open Flow network since many organizations apply Open Flow in their data centers (for example, Google). However, current version of Open Flow does not support Inter-domain technology. In other words, from the GUI, users cannot know the actual positions of other hosts and Open Flow switches in another domains. When performing SLA, it is inconvenient for management and maintenance since managers cannot know correct routing paths. Therefore, this paper will enhance our previous work of Inter-domain network topology and flow display system and Floodlight to study and implement host information demonstration.
