A Game Based Multi-domain Protection Scheme in WDM Optical Network

In order to provide good quality of survivability in the WDM (Wavelength Division Multiplexing) optical network and keep the network load in a good condition, a game based muti-domain protection scheme is proposed in this paper. Game theory, Nash equilibrium and Pareto Optimality of micro-economics are introduced in this scheme for considering benefits of both users and network providers to guarantee the reasonability of survivable routing and achieve all-win. Finally, the proposed protection scheme is implemented by simulation, and the experiment results show that the proposed scheme can reach these design goals.
