| Summary: | 碩士 === 國立成功大學 === 數學系應用數學碩博士班 === 90 === Although ATM(Asynchronous Transfer Mode) uses ATD(Asynchronous Time Division) to increase the channel utility rate, the improvement for jams in the network is still limited. The reason may lie in the fact that the ATM uses the shortest path algorithm to find the primary virtual paths during the design phase which makes the routes focus too much on some transmission path. This prevents from the use of bandwidth sharing rule to release extra bandwidth. In this thesis, first, we observe the phenomenon by numerical examples, and then try to use the concept of accumulative weights to decrease the required spare resource ratio in an ATM network. Our extensive simulation results show that the introduction of accumulative weights successfully achieve the expected goal.
