IP with generalized multi-protocol label switching (GMPLS) directly over WDM is recognized as the promising architecture for next generation network (NGN), which utilizes all-optical transparent model in its physical layer without optical-electrical-optical (OEO) conversion. However, the architecture itself raises the coupling issue of optical and network layers, which just begins drawing the attention of researchers. We present a systematic approach for evaluating performance of an illustrative 40Gbps 16 λ IP/GMPLS over WDM network, considering both linear and nonlinear optical impairments. Results obtained show that the effective network performance parameters are affected by optical impairment apparently.
