Many recent studies have convincingly demonstrated that network traffic exhibits a noticeable self-similar nature which has a considerable impact on network performance. Therefore, we present a novel scheme for optical burst switching (OBS) networks, called logical cascaded private subnet. We define the concept of `canoe' relative to `cluster' in self-similar traffic, and introduce a new device named payload segregator at the edge node as a gateway to the core node in OBS networks. According to the changes in the edge node framework, we put forward the concept of cluster private subnet and canoe private subnet in the core node correspondingly. Performance study indicates that, the new scheme is robust under self-similar traffic
