中文摘要 | ATM網路中,虛擬路徑觀念的提出大幅簡化了交換機對細胞的處理,若配合較佳的資源管理策略,將可使虛擬通道的建立更快速更有效率。虛擬路徑的建構方式及資源管理配置的策略關係著系統運作的效能。本文繼提出一個以區域(zone)為觀念的新架構及對應的虛擬路徑建立策略,並配合相關的頻寬控制法、重新繞徑策略、資源管理方式來分析各種相關之效能後;接著探討多播繞策略等問題,並提出多種演算法,分析此模型的各種特性。最後利用模擬程式驗證本模型的各項效能,如頻寬利用率、阻塞機率、重新繞徑比率等等。 |
英文摘要 | In ATM networks, the concept of virtual path (VP) greatly simplifies cell processing in ATM switches; and good strategies of resource management enable virtual channel connections (VCC) to be established more quickly and efficiently. The method of constructing virtual paths and the strategies of managing and allocating resources greatly affect the performance of the system operation. We propose a new architecture, called zone, and corresponding methods of constituting virtual paths; various methods and strategies, such as bandwidth control rerouting strategy, and resource management methods, are studied. This paper focuses on multicast routing and analyzes some algorithms in this model. Simulation results show the excellent performance of our model in bandwidth utilization, blocking probability, and rerouting ratio. |
