摘要：

The impact of link failures on the performance of multihop lightwave networks such as shufflenet (SN), hypercube (HC), is evaluated by detailed computer simulation study. The degradation in network throughput of the above networks due to link failures is compared for several routing schemes, namely store-and-forward (SF), hot-potato (HP), and single-buffer deflection (DF) routing. The throughput degradation due to link failures is found to be minimum for HP routing. The HC network is much better suited for surviving multiple failures than SN of the same size. The simulation study is also extended to consider the impact of link failures in multiwavelength shufflenet (MWSN) employing dynamic wavelength routing. For MWSN, the degradation in throughput increases with in, the number of wavelengths per fiber link. (C) 1998 Elsevier Science B.V.
