A service-based Routing Wavelength Assignment (RWA) algorithm for power optical transport networks is proposed. The algorithm is designed to solve the problem of multi-service level request routing wavelength assignment under the complex power optical transport network topology. Firstly, according to the situation of complex network and the status of service request, it completes the combination of service request and the routing of cross-domain services. Secondly, according to the intra-domain and inter-domain priority setting policies, the priorities of service requests are set, Wavelength allocation using packet wavelength assignment algorithm. The simulation results show that the proposed algorithm can effectively reduce the blocking rate of network requests and improve the utilization rate of optical transport network in handling large-scale and complex network topology and multi-service routing wavelength assignment.
