Abstract(in English)	Although OSPF (Open Shortest Path First) as a major routing protocol is used on networks, it has a Router Dead Interval problem. To solve these problems, we propose a faster OSPF route reconstruction method. The proposed method marks IP packets and detect the DR failure fast by monitoring a change of marked IP packet flows. We implemented our enhancement OSPF on 'quagga' which is one of open source OSPF program based on RFC2328. In this report, we show the performance evaluation results of our enhancement OSPF on virtualization router network. We confirmed that our method reduces the route recovery time from 40 seconds to 1.46 seconds.
