In recent years, the WDM networks have received much attention as the Internet backbone networks due to the explosive growth of the Internet IP-based traffic. The Optical burst switching (OBS) is proposed as an effective optical switching technology in the WDM networks [1]. OBS has the advantages in 1) the high usage rate of the bandwidth 2) no necessity of optical buffer. However OBS has a burst-collision problem in the networks. The deflection routing is proposed as one of means to solve this problem. In this paper, we propose a new routing method of using deflection routing. Also, we show the possibility that QoS can be guaranteed by the classification of the traffic in the future.
