Abstract: As the core part of next generation backbone transmission network, multi-granularity transport networks have attracted more and more attention because of the advantages of high bandwidth and energy saving. However, due to the growing tendency of users’ bandwidth in demand and the increasing tense situation of global electricity resources, it’s important to further improve the capacity and performance of data network transmission. This paper studies the features that the multi-granularity transport networks can establish new paths and delete old paths in a high speed, introduces the ideas of game equilibrium into traffic guidance process, and designs a kind of energy-saving guidance algorithm based on game theory that can achieve the traffic grooming and energy-saving effectively at the same time. Finally, this paper simulates the proposed algorithm on the topologies of EON and CERNet2, the results show that the algorithm is feasible and effective.
