| dc.description.abstract | 隨著電腦網路的快速成長以及電腦儲存設備成本的降低，越來越多個人電腦使用者能夠負擔大容量的硬碟與高速網路服務。一個使用者擁有多個儲存設備，並且將重要或常用的檔案備份在不同主機上，已經是非常普遍的現象；進一步透過網路有效率而且可靠地存取、共享、備份檔案的使用者需求也逐步升高。然而，現有的分散式檔案系統大多是為了區域網路中的檔案分享而設計，它們的設計目的是提供集中式的檔案儲存空間，以降低當時昂貴的儲存設備成本及簡化管理工作。這些早期的分散式檔案系統無法順暢的支援廣域網路中的檔案分享與存取。此外，這些分散式檔案系統只能提供固定的檔案介面，缺乏使檔案介面可以再被繼承、延伸以達到客製化的彈性。
在本篇論文中，我們設計一個支援廣域網路中檔案分享、存取、備份的物件導向分散式檔案系統。本系統是一個整合現有實體檔案系統的邏輯性檔案系統，對本地端檔案及遠端檔案提供一致的存取方式。我們選擇將系統建置在MOSP上，此乃鑒於MOSP開發網路物件導向系統的方便性，以及它整合異質性平台與網路通訊協定的能力，能幫助我們達成支援無縫隙、無界線檔案分享的目標。此外，我們提出了一個新的副本管理設計用以解決廣域網路中檔案分享的效能表現及可靠度等問題。 | zh_TW |
| dc.description.abstract | With the rapid growth of computer networks and the price-reduction of computer storage, more and more personal computer users are able to afford large hard drives and high speed internet services. Now, it is common for personal users to possess more than one storage device on different computers and backup their critical files. This is an increased demand to access, share and backup files remotely through the Internet or other networks with reasonable performance and reliability. However, most of the current distributed file systems are designed for LANs, and intended to provide centralized file servers for use in Intranet environments to eliminate storage costs and management requirements. They do not gracefully handle inter-platform file access, sharing and backup over the WAN. Besides, most current distributed file systems provide fixed interfaces, not offering the flexibility for programmers or service providers to extend interfaces to meet customized requirements.
In this thesis, we are developing an object-oriented distributed file system that supports file access, sharing and replication over the WAN. The system is a logical file system that can integrate all kinds of underlying physical file systems, providing an identical way to manipulate local and remote files. We build our system on MOSP because it provides a simple way to develop an object-oriented networked system and it accommodates heterogeneous platforms and network protocols, which helps achieve our goal of supporting boundless and seamless file sharing over the WAN. In addition, we propose a new replication management mechanism, which addresses the performance and reliability concerns. | en |
