    Abstract

    The concept of Shared Risk Link Group (SRLG) is introduced in WDM optical networks, in which the work path and the protection path should be disjointed with SRLG. A new dynamic shared path protection algorithm based on SRLG constraint is proposed,which meets the K pairs services called K-Dynamic Link Weight Configuration (K-DLWC) algorithm. The key function of this algorithm is to make the definitions of two dynamic weights of a link. The algorithm can be used to synthetically cope with some important problems such as SRLG constraints and local optimization in calculating the work path and the protection path.
