In this paper,the optimal design of WDM multi fiber ring (MFR) networks isdiscussed.New integer linear programming (ILP) formulations are proposed to solve it.The optimal objective is to minimize the averaged node ports number.It can maximize the cost effectiveness of the designed MFR networks.By using these algorithms,the network performance of different type of MFR architectures (bidirectional and unidirectional) employing various routing schemes (wavelength path and virtual wavelength path) are analyzed.The obtained results can be used as a criterion in selecting the most suitable MFR architecture.
