摘要：

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.
