摘要：
The present invention discloses a wavelength division multiplexing (WDM) network path search method and system. The method includes: step A, searching out a network element linked list from a source network element of a service to a destination network element according to a inter-network element connection; step B, performing a port search on the network element linked list, performing a validity check on a found node, and ending the search when an invalid node is found; and step C, sorting out a path linked list of all possible paths according to path topology structure data searched out. The searching efficiency is improved by the present invention.
