Risk balancing routing assignment mechanism based software defined optical network service importance

The software defined optical network (SDON) service plays an important role in the production and operation of the network system. It's important to solve the problem of how to reduce the risk and distribute the service path more rationally. However, most of the existing algorithms do not take into account service importance. In this paper, a risk balancing routing assignment mechanism based service importance is proposed. Finally, the simulation shows that compared with the other two methods, the SIRBRM can reduce the link risk and the overall network risk, make the service distribution more uniform.
