Title:	TANet區網國內ISP訊務品質之監測與分析 The Transmission Quality Analysis of TANet ISP Traffic

Abstract:	隨著TANet區網routers 間訊務交換量的快速成長與骨幹架構的更新, TANet使用者開始對區網連外VC的傳輸品質產生好奇. 由於TANet 15個區網連往國內各ISP的訊務均經由 Moe ATM Switch 節點下接之 ISP_router交換,我們藉由 SNMP網管應用程式擷取各區網連往ISP_router的15個VC,動態地產生相對的 MRTG 設定檔;並週期性地驅動 MRTG 萃取Per-VC的 In/Out Cell及Cell Drop MIB. 本MRTG Traffic Web Pages (http://atmf.tyc.edu.tw) 顯示的: 各區網與ISP間訊務與傳輸封包遺失量的統計,可供各區使用者作即時地監測其ISP訊務量與傳輸封包遺失,協助使用者及網管人員較具體地了解其連外網路的實際傳輸狀況及推估存在的傳輸瓶頸. 我們也運用MRTG儲存的 Per-VC In/Out Cell, Cell Drop記錄檔,統計出Per-ISP-VC之單日CDR (Cell_Drop_Ratio); 做為衡量各區網與ISP間訊務傳輸的品質指標;分析各區網ISP訊務傳輸品質與延徑網段頻寬資源的關係。並進一步比較ISP_router頻寬資源擴增前後, 各區網 ISP訊務量的成長與相對的單日 CDR傳輸品質變化狀況.
