Summary: | 碩士 === 國立中興大學 === 應用數學系 === 85 === This paper presents a quantitative scheme forevaluating and
improving the performance of networktopology. First, from the
status of a network, we define aset of evaluating parameters and
propose strategies based on the evaluating parameters.
According to the evaluating results, we canimprove the network
topology by using the scheme weproposed. In plainly, we improve
the network topologyby enlarging the buffer size of switching
nodes,increasing the bandwidth of links, and re-dimensionthe
connection of links. From a network manager's view, we must
evaluatethe network topology by considering the entire
networkperformance. So, we adopt three parameters : throughput,
packet delay time, and packet loss ratio, as the performance
indices to evaluate if the proposed schemecan improve the
network topology. Finally, we use simulation to verify that
theproposed scheme can improve the network topology,
whichresults in increasing the entire network throughputand
reducing the packet delay and packet loss ratio.
