Aplikasi rangkaian seperti FTP, WWW, Mirroring dsb. pada masa ini dikendalikan dengan sedikit atau tiada pengetahuan tentang ciri-ciri rangkaian asas. Aplikasi ini boleh beroperasi dengan lebih cekap jika ciri-ciri rangkaian diketahui dan/atau disediakan untuk aplikasi berkenaan. Tetapi ciri rangkaian sukar diperolehi. Kumpulan kerja Metrik Prestasi IP (IETF-IPPM-WG) sedang berusaha membangunkan satu set metrik yang akan mencirikan perkhidmatan penghantaran data Internet (rangkaian). Beberapa alat sedang dibangunkan untuk pengukuran metrik ini. Ini biasanya melibatkan pengukuran aktif atau memerlukan pengubahsuaian dalam aplikasi. Kedua-dua teknik mempunyai kelemahan mereka. Dalam kerja ini, kami menunjukkan pendekatan baharu dan lebih praktikal untuk menganggar ciri rangkaian. Ini melibatkan pengumpulan dan menganalisis pengalaman rangkaian. Pengalaman tersebut adalah dalam bentuk statistik trafik, maklumat yang disuling daripada aktiviti berkaitan pengurusan dan log tersedia di mana-mana (log akses sotong, log mel, log ftp dll. ) aplikasi rangkaian. Analisis pengalaman ini memberikan anggaran ciri-ciri rangkaian asas. Untuk menilai konsep yang telah kami bangunkan dan bereksperimen dengan sistem di mana ciri rangkaian dijana dengan menganalisis log dan statistik trafik. Ciri-ciri rangkaian disediakan kepada pelanggan rangkaian dan pentadbir oleh pelayan Rangkaian Prestasi Metrik (NPM). Pelayan ini diakses menggunakan protokol pengurusan rangkaian standard. Keputusan penilaian dibentangkan dan rangka kerja untuk pengendalian operasi rangkaian yang cekap, menggunakan ciri rangkaian digariskan.

Abstract: Network applications such as FTP, WWW, Mirroring etc. are presently operated with little or no knowledge about the characteristics of the underlying network. These applications could operate more efficiently if the characteristics of the network are known and/or are made available to the concerned application. But network characteristics are hard to come by. The IP Performance Metrics working group (IETF-IPPM-WG) is working on developing a set of metrics that will characterize Internet data delivery services (networks). Some tools are being developed for measurements of these metrics. These generally involve active measurements or require modificationsin applications. Both techniques have their drawbacks. In this work, we show a new and more practical approach of estimating network characteristics. This involves gathering and analyzing the network's experience. The experience is in the form of traffic statistics, information distilled from management related activities and ubiquitously available logs (squid access logs, mail logs, ftp logs etc. ) of network applications. An analysis of this experience provides an estimate of the characteristics of the underlying network. To evaluate the concept we have developed and experimented with a system wherein the network characteristics are generated by analyzing the logs and traffic statistics. The network characteristics are made available to network clients and administrators by Network Performance Metric (NPM) servers. These servers are accessed using standard network management protocols. Results of the evaluation are presented and a framework for efficient operation of network operations, using the network characteristics is outlined.
