ince the Internet was defined by TCP/IP suite, it cannot accommodate today's large amount of devices and huge amount of internet traffic which were not considered when it was invented. Also current routing is wasting network resource by utilizing link unfairly. One of the approaches to solve these problems is a centralized routing architecture such as SDN. In this paper, we proposed “Automatic Re-routing with Loss Detection” architecture. Packet loss is detected with queue stat message of Openflow protocol, then Re-routing module tries to find bypass and applies to flow tables. Through an emulation with actual controller and virtual network, we showed that proposed scheme reduced overall average loss rate and improved loss fairness over the net-work by standardizing loss rate of each traffic
