Abstract: This article presents the first distributed alorithm to solve the logical topology reconfiguration problem for IP over WDM networks under dynamic traffic. The algorithm is developed based on the centralized approach proposed in [Tran and Killat, Dynamic reconfiguration of logical topology for WDM networks under traffic changes: 2008]. The performance of the proposed distributed algorithm, which lends itself to a protocol implementation, is investigated using European 18-node network. The results show that our algorithm fulfils all requirements of the reconfiguration process, such as no service disruption, load balancing in the new logical topology while allowing to add and to delete multiple lightpaths. Moreover, the distributed approach offers a high scalability. Not limited to small or medium-sized networks as the centralized model in [Tran and Killat, Dynamic reconfiguration of logical topology for WDM networks under traffic changes: 2008], this algorithm can be applied to large networks with the computation time increasing linearly with the network size.
