We describe here a burst scheduling algorithm to reduce burst overlapping with fiber delay lines (FDLs) in optical burst switching (OBS) network, and hence to improve the quality of service (QoS). We consider TAG (tell-and-go) protocol where many lightpaths pass in a given link and burst overlap may occur. In an intermediate node having two incoming links and one outgoing link at lower traffic loads,...
This paper present an investigation into the effect on the performance of an optical network based on OADM by changing different filters at the receiver side. The calculated average BER and with the help of eye diagrams analyze the response of the filter Bessel, Butterworth and Chebyshev filter and compare the results of the three filters responses in OADM based environment. With the help of OADM...
In this paper the FFH-OCDMA system is modeled and studied for its suitability for local access upgrade with WDM at the backbone. Throughput comparison of different OCDMA schemes have shown FFH-OCDMA scheme to be suitable for high traffic loads. Accurate modeling of the FFH-OCDMA system is necessary to analyze the OCDMA/WDM system considering the WDM non-linearities and the physical layer impairments...
