Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 86 === Internet traffic style remains unknown in current environment.
This is the reason why more circuit deployment is the only
solution to bandwidth insufficency. Lack of wide area network
traffic measurement and analysis always leads to the
embarrassment of performance assessment. Further, even the
bandwidth usage efficiency can not be evaluated.Traditional
network measurement and analysis always base on the metric of
packet. Since different applications behave differently, it is
not feasible to explain the attribute of applications totally on
the basis of packet volume.This research is going to introduce
the concept of "Flow". We are going to use the flow model as new
metrics for traffic measurement and analysis. Comparisions to
the legacy packet based methods will be given.To solve the
difficulty of wide area network measurement and analysis, we
propose a system suitable for not only wide area networks but
also local area networks. Design and implementation issues are
described in the thesis.
