碩士 === 國立中興大學 === 資訊科學學系 === 83 === ATM 是一個非常有效率的傳輸模式, 它能提供固定和不固定傳輸速率的網 路服務, 以滿足各種不同應用的需求. 另一方面,ATM 區域網路模擬則可 說是邁入 ATM 網路的開始. 如何在尚未建構 ATM 區域網路之前, 能了解 ATM 區域網路模擬的網路效能, 成為本文的目標. 藉著 Libra 所提供的 交換器網路環境,提供有關連線的建立與資料的切割與重組, 促成 ATM 區 域網路模擬得以實作的方式進行. 本文首先探討目前引進 ATM 區域網路 的可行方案, 與其優缺點的比較, 再透過模擬的方式,對此網路架構進行 更深入的研究,同時更詳細的介紹實作上的細節及解決的方法, 最後則是 對於模擬結果的分析及效能的研究, 以發現實際遭遇的問題, 及推斷協定 的正確性. ATM is a very flexible transfer mode, It may support either constant bit rate or variable bit rate network service, and to satisfy the requirements of different applications. Since no organization can afford to abandon the applications written for legacy LANs, ATM LAN Emulation is critical in the process of moving toward all-ATM networks. In this work, we focus on the performance of ATM LAN emulation. By the aids of an ATM simulator called Libra, which provides the platform for connection management and data sengmented and reassembled, we have built an ATM LAN emulation simulatior. First of all, the methods for introducing ATM into local area will be described and a comparison is given in the first section in this thesis, The detail of the simulation on ATM LAN emulation protocol and solutions we propose will be described in section 2. The result of evaluation and performance analysis will be discussed in section 3. finally, some conclusion will be drawn in section 4.
