We address the issue of traffic-oblivious routing (i.e., robust routing) in WDM networks dealing with both link and node failures under load-balancing architectures. Two distinct schemes are proposed. One is static with the goal of minimizing total network cost given a set of multiple failures. The other considers dynamic network environment (i.e., connection requests arrive one after another), and is designed against the failures aiming at the maximum network throughput. We manifest by simulation that both of these two schemes perform better than the previously proposed protection schemes as well as the unprotected ones.
