中文摘要 | 國家寬頻實驗網路(NBEN)是電信國家型科技計劃的一部份,其重點任務包括:建構未來共同使用之寬頻網際網路架構、掌握未來網際網路之相關技術、發展各式寬頻接取技術及其網路應用環境、支援各種互動式寬頻應用之建立與實測及作為我國通訊研發成果的展示及互連測試環境。根據九十年及九十一年前半年的障礙統計分析發現,在NBEN發生的障礙中,原因不詳佔多數,為改善這種現象,減少原因不詳之障礙與區隔出障礙發生點,中華電信研究所NBEN網管中心決定進行NBEN網管機制的改善工作,改善目標有:減少原因不明之障礙、界定障礙所在及計算NBEN網路品質。為達成此三點目標,NBEN網管改善工作將以下列三個方向著手進行: (1)變更NBEN網管系統監控架構,使監控資料有助於釐清障礙發生原因及發生點。 (2)引進“Chariot網路性能量測軟體”進行NBEN傳輸品質即時量測。 (3)建構NBEN網路可用度模式,並利用監控所得之障礙資料計算NBEN網路可用度。 本文將敘述NBEN的網路架構及網管機制改善的措施與改善後呈現之成果。 |
英文摘要 | National Broadband Experimental network(NBEN) is the infrastructure for Taiwan’s National Telecommunication development Program(NTP), a government supported project to construct the future Broadband Internet architecture for developing various Broadband access and internet realtio technologies and applications that will serve as a testbed and interoperating platform for telecommunication societies in Taiwan. Network performance and reliability therefore have always been NBEN’s biggest challenges. According to the failure statistics collected since 2001, the unknown reason faults are the most frequent failures of NBEN. To help solve this problem, CHTTL NBEN Managing center decided to improve NBEN network management system intelligence to make it more effective and efficient. Decreasing unknown reason faults, locating faults and computing network qulity are three design goals for this NBEN improvement mechanism. Three tasks are defined as follows to achieve these design goals: 1.Easily locate and isolate network faults by improving network monitor architecture and procedures. 2.Collect network real time performance data by using real time throughput testing tools. 3.construct network availity model and collect monitoring information to compute network availability. The NBEN network architecture will by briefly described in the introduction. The improving NMS procedures and the improvement after applying these new design will be then further described. |
