【Abstract】 Based on the characteristic of multi-granularity networks,two shared protection schemes for multi-granularity optical networks were proposed,which provide protection for the working paths based on waveband granularity and wavelength granularity respectively.The simulation results show that the proposed schmemes have better performance than dedicate protection schemes.Based on the analysis of these simulation results,the effect of various network parameters on the two schemes were investigated,which can be used as references in choosing protection schemes.更多还原
