Abstract
The path-protection scheme in WDM optical networks is addressed, and also the conception of the SRLG (Shared Risk Link Group) is introduced. A new link protection method is proposed, i.e. unrelated SRLG-based Shared-path protection (uSS). The concept of the spare-path set and wavelength-levels cited, the complexity of the algorism is analyzed. The simulations results show that the developed iSS performs well in terms of protection efficiency and the viability of the whole networks , while resource utilized ratio is improved enormously by contraries the possibility of invalidation of both the work-path and the protection-path.
