In this paper, the optimization design of WDM multi-fiber ring network (MFR) is discussed, and a new integer linear programming formula is proposed to solve the problem. The optimization goal is to minimize the average number of nodes, which can be used as the optimization target The designed multi-fiber ring network is the most economical and efficient.With the proposed algorithm, we quantitatively analyze the network performance of several MFR structures (one-way and two-way) with different routing schemes (wavelength channels and virtual wavelength channels) The conclusions obtained in this paper can be used as a reference for choosing the appropriate MFR structure
