摘要：

The characteristics of the multi-granularity optical cross connect (MG-OXC) node with the tunable wavelength converters is analyzed. A new dynamic routing and wavelength assignment algorithm which is applied in multi-granularity optical switching network is also proposed. The performance of the MG-OXC with tunable optical converters, compared with traditional OXC and MG-OXC, is evaluated with help of numerical calculations under NSFNET topology. The results show that the performance of the network with MG-OXC with tunable wavelength converters is superior to that of the network composed with only traditional OXC and MG-OXC.
