Abstract

【課題】ネットワークの通信品質の計測精度が向上し、かつ、同通信品質に関する統計情報を管理するためのテーブルを小規模にできるノード装置を提供する。 【解決手段】Ｚ－ｌｉｓｔ２１２に重要度を判定するためのデータがあり、重要度判別部２１３でＺ－ｌｉｓｔ２１２から該当フローの重要度が判別される。Ｅ－ｌｉｓｔ２２２で監視重要度の高いフローの統計データが格納され、入替え判定部２２１で該当フローの重要度とＥ－ｌｉｓｔ２２２内の重要度から入替え判定が行われる。振分部２３１で入替え判定部２２１からのデータがパケット情報と統計情報で各処理部に振り分けられ、統計情報品質計測部２３２で、統計情報で伝達された部分の品質が計測され、通常パケット品質計測部２３３で、パケット情報で伝達された部分の品質が計測され、統合品質計算部２３４で通常パケット及び統計情報の各品質が合算されて品質結果２３５で記録される。
