Performance Analysis of Packet Length in 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 analysis on packet length for multiple optical channel, which coupled Ethernet with WDM to decrease the average queuing delay and increases the normalized throughput. The performances of three channels with several range of packet length were evaluated by employing discrete event simulator. It has been proved that longer packets gives better performance on throughput, however it does increased the average queuing delay. Packet length in range of 4096-8192 bits per packets gave similar result of throughput with normal packet length for Ethernet (512-12144 bits per packets).
