In this paper, a p-cycle generation algorithm is proposed that can protect service of static traffic model in WDM network. As the basic p-cycle sets calculated by algorithm such as the Straddle Link Algorithm (SLA) always contain a straddle link in it. That is why the protection efficiency is higher than Bidirectional Line Switch Ring (BLSR). Any idle resource can be used for traffic restoration. But if the resource is not configured carefully then not all the resource of idle state can be utilized efficiently.
