Abstract:	資料網格(data grid)為一網格系統(Grid system)之擴充版本，它可以整合分散在不同地理位置之計算資源與儲存資源，以茲服務使用者。同時，隨著大規模且複雜的研究持續地進行，資料網格中的網路拓樸與工作站也因而持續不斷地擴張，使得分析一個新的資源仲介代理人(Resource Broker)排程程式之績效或分析平行地由各地工作站傳送某一檔案之片段，給其使用者之網路行為異常困難，即，協同傳送機制(co-allocation scheme)。為此，我們提出一個化簡網路拓樸之方法，稱之為Tree-to-Star Reduction method (簡稱為TSR)，目標是將一個複雜的樹狀網路拓樸化簡成一個等效的星狀拓樸，以降低研究人員在分析協同傳送機制之網路行為時的負擔，同時TSR也可以用來化簡其它平行分散式系統之樹狀網路拓樸，例如：網格系統、雲端計算與P2P系統，以利於分析檔案傳遞時間(job turnaround time)等，而不失其準確性。 A data grid, the extension of a Grid system, often integrates geographically dispersed computational and storage resources. Users are able to execute large-scale applications and store their experimental data and/or produced data in various areas in the data girds, such as physics, astronomy, and seismology. However, it is difficult for researchers to evaluate the performance of proposed algorithm since a data grid is often large in scale, heterogeneous in its participating resources, and complicated in its architecture and network topology. Hence, we propose a topology reduction approach, called the Tree-to-Star Reduction method (TSR for short), with which we can reduce a complicated tree topology to a star in a data grid without impacting the evaluation accuracy and correctness of data transmission delays for a co-allocation scheme. The delivery star simplifies the evaluation and analytical complexities of the network delay time of a co-allocation scheme. Nevertheless, the TSR is also applicable to reducing the complexity of a delivery tree in other distribution and parallel systems, e.g., a grid computing, cloud computing, and P2P system.
