Performance Analysis of Throughput and Queuing Delay for Multiple Optical Channels for Local Area Network

The advances in Wavelength Division Multiplexing (WDM) technology have tremendously increased the bandwidth of a single fiber optic, for local and metropolitan area network (LAN and MAN). This paper presents and discusses a new network environment that is multiple optical channel, which coupled Ethernet with WDM to decrease the average queuing delay and increases the normalized throughput. The performances of three channels are evaluated with different network parameters using discrete event simulator called OMNeT++. In this paper it has been proved that RS BEB algorithms show the best throughput for three data rates. Moreover, in average queuing delay and RS BEB shows the lowest delay despite the others algorithms. It has been observed from this work that an increase in the number of nodes, the percentage of normalized throughput decreasing is less than 20% for every additional node in the network.
