A Novel Approach for Static RWA based PLI Evaluation of WDM Networks in "WDM-NetSoft"

In recent years, network simulators [1] - [5] have become accustomed to the analysis and design of optical fiber communication networks in the academy and industry. In this work we present the new network software WDM-NetSoft for planning, analyzing and designing wavelength routed optic networks. The software analyzes network for IndiaNet topology as a long haul network. In addition, the software considers different modulation formats along with physical layer impairments for the networks performance evaluation.Traffic in long haul networks has become versatile and supports different service requirements. The current 10 Gbps network needs to be upgraded to 40/112 Gbps to meet the demand for different services (s). Mixed line rate (MLR) wavelength-division multiplexed (WDM) optical networks are a low cost alternative for future networks. MLR networks support various line rates on various wavelengths within a fiber. The physical impairments include accumulated ASE(amplified spontaneous emission) noise, chromatic dispersion, switch crosstalk, PMD(Polarization Mode Dispersion) effects, & fiber nonlinearities. Therefore, this paper demonstrates the functionality of our software to analyze a variety of practical WDM networks.
