Many existing literatures investigated the survivable routing and wavelength assignment strategies on WDM networks from the perspective of source routing which implies that the size of the network will heavily limit the scalability and the tractability of the problem. In this paper, we will probe into the same problem by means of the distributed processing within each node in the network. The proposed flooding based approach just uses the simple broadcast operation to the output ports by looking up the tables and can be easily integrated into the regular routing protocols implemented in each node. The simulations are made to verify the performance of this framework with comparison to the centralized version of the solution.
