Comparative Study for Proposed Algorithm for All-Optical Network with Negative Acknowledgement (AO-NACK)

Abstract

This paper focuses on an efficient packet delivery mechanism for all-optical network. As optical networks use Wavelength Division Multiplexing (WDM) thus information can be transmitted in parallel. This paper focuses on achieving 100 percent throughput via using buffer and negative acknowledgement mechanisms. The proposed mechanism also reduces un-necessary traffic in the network while keeping the re-transmission of packets in check using optical buffer. For a typical four inputs and outputs switch without buffer some thousands of packets are dropped which can be bring down to some tens of packet with only a buffer size of 8 packets. Thus the re-transmitted packets also get reduced significantly.
