摘要
隨著全球資訊時代的到來，寬頻需求已成為主流趨勢，而應用於寬頻電信的ATM網路，因為可以同時提供數據、語音、影像等多類不同性質的網路服務並可確保其服務品質，故亦成為國軍建置穩定、可靠、快速的廣域網路所倚賴的主要技術。文中首先介紹ATM網路技術、各服務類別與參數型態，其次就ATM頻寬使用效能部份作較為深入之介紹與探討，以讓大家對ATM網路應具備之功能與目標能有更進一步的認識與瞭解。
在廣域網路中，頻寬是最昂貴的部分，建置廣域網路的預算不會因為使用者的需求增加10倍也隨之增加10倍，在ATM網路中，頻寬資源主要是由多個使用者共享，因此要如何動態地分配頻寬資源給各個使用者，又如何在分配資源的同時確保其服務品質(QoS)，是相當重要的課題。本文將針對設計好的ATM網路架構，建立分析模式來評估不同系統參數設定與應用效能間之關係，期能提供ATM網路使用效能與確保使用者服務品質之研究參考依據。

ABSTRACT
Broadband requirement has become the main trend of global information platform. ATM network that deployed at broadband telecom is capable to provide data, voice and video at the same time and ensures their quality of service. So it has become the main technology to build a stable, reliable and fast wide area network (WAN) in military. Firstly, this research covers some ATM network technology, various service types and parameters. Secondly, we will focus on the efficiency of ATM bandwidth utilization and let everyone understand more about ATM network’s function and its goal.
Bandwidth is the most expensive part in WAN, and it is impossible to add ten times of budget in WAN to follow customers’ ten times of bandwidth requirement. Because many users in ATM network could share bandwidth resource, how do we allocate these bandwidth resource to these users and how do we ensure their Quality of Service (QoS) will be an important issue. This research will focus on designed ATM architecture to analysis how do the different parameters affect ATM network utilization and how do we ensure user’s QoS . Hope it could be helpful to related research.
