A contribution to the problem of links only for protection in WDM mesh networks

Abstract

This paper presents a WDM mesh network planning and designing that satisfies given demands with a predefined way, a m:N WDM and optical fiber system shared protection (OMS-SP) and a restoration approach. This restoration approach is based on the shortest path algorithm ignoring the failed link, so a dynamic restoration method is used. At first, the restoration uses links only for protection and at second, the restoration does not use such links .The results are compared on optical path layer.
