Analysis of Optical WDM Network Topologies with Application of LRWC Under symmetric Erlang - C Traffic

Abstract

This paper analyses an Optical WDM network model with application of Limited Range Wavelength Converters for online routing with a wavelength assignment scheme under symmetric Erlang-C traffic. Distinct wavelengths have been assigned to short and long hop connections by wavelength conversion besides attempt to reserve an identical wavelength across all nodes. Probabilistic model for traffic has been developed employing both ring and star topology networks. A mathematical model has been further devised and its call blocking probability has been enunciated. Compared performance analysis of both topologies has been presented with an investigation on collective impacts of various traffic parameters on transmission.
