Abstract :
Path protection with shared spares is a general dependable wavelength routing (DWR) method to improve the blocking performance while minimizing the required spare resources. However, in a dynamic traffic environment, this may still lead to poor performance. This paper presents a dependable wavelength routing with spare rerouting mechanism (DWR SR) to improve the blocking performance. Extensive simulation experiments were conducted to study the performance of the proposed DWR SR method. The results show that DWR SR can effectively alleviate the dynamic traffic constraint on the spare lightpaths and reduce the blocking probability
