摘要: 障礙管理(Fault management)，是ISO 7498-4所定義網路管理的五大重要功能之一。其中障礙的偵測(fault detection)及通知(notification)為整個障礙管理極為重要的前置處理程序，它標示著網管人員處置障礙所能運用的時間長度，並且關係著後續障礙處理的進行及品質。 隨著網際網路的快速發展與網路環境的日益複雜，快速的障礙辨識和過濾重覆的障礙訊息，已成為提升障礙管理品質的重要課題。本篇論文將提出一種新的障礙通告發佈系統，稱為「RSS障礙通告發佈系統」(RFNS: RSS Fault Notification System)，藉由系統的「障礙政策制訂模組」以制定障礙通告的相關政策(policy)，作為進行障礙通告的發佈依據。利用「障礙萃取器」來過濾重覆出現的障礙通告，藉以降低因發佈障礙通告所需耗用的網路頻寬及系統資源；透過「RSS處理器」將障礙通告轉換成RSS格式，並以新聞的方式快速而即時的發佈給相關網管人員。本文將實作RFNS系統，並藉由實驗模擬進行績效分析。最後，實驗結果證實經由RFNS的執行，確實能夠達到大幅降低因障礙通告發佈所佔用的網路頻寬與減少其檔案大小，同時亦經由縮短障礙偵測時間，進而降低整體障礙處理所花費的時間。此外，並精萃了障礙通告的內容，讓網管人員能即時地和正確地獲得相關的障礙資訊。

Abstract: The fault management is one of five essential network management tasks defined by ISO 7498-4. Fault detection and notification are the key pre-process of all the fault management, it is noted that the network manager can use the disposal time of the faults, and is also related to the activity and quality of follow-up processing. With the fast development and the increasingly complex environment of Internet, rapid fault identification and duplicate messages filtering is one of essential subject to enhance the fault management quality. This paper proposes a novel fault notification issue system, called RFNS. The ”Fault Policy Refine Module” formulates the related policy of fault notification via RFNS system. Also, the RFNS system is to solve the fault notification issue and to utilize ”Fault Extractor” module for filtering duplicate fault notification in reducing network bandwidth and system resources of publishing fault notification. Then, the notification will convert into the RSS format through the ”RSS Processor” and immediately issue the related network manager by news. Also, we will implement the RFNS system and perform experimental simulations for performance analysis. Consequently, the final results indicate that lower the wasted network bandwidth, lessen the file size of fault notification and shorten the total amount time in faults detection and processing through the implementation of RFNS. In addition, the RFNS system extracts the main content of fault notifications, and therefore the network manager can obtain real-time and accurate fault information.
