Abstract

　スイッチのＶＬＡＮ設定情報の管理において、スイッチの冗長構成によって通信経路が複数存在するようなネットワークで、複数のＶＬＡＮをまたぐような場合であっても通信範囲を特定できるようにする。 　ＶＬＡＮ－ＩＤが定められた機器をＫＥＹとし、当該機器から通信可能なＶＬＡＮ－ＩＤが定められた機器をＶＬＡＵＥとし、各ＫＥＹおよび各ＶＡＬＵＥが機器名とＶＬＡＮ－ＩＤの組で表されるＶＬＡＮ通信可否ハッシュテーブルを作成しておく。そして、ネットワーク管理者等に指定されたＫＥＹを起点として、冗長構成を示す冗長構成テーブルやルーティング可能か否かを示すルーティングテーブルを参照しながら、ＫＥＹから通信可能なＶＬＡＵＥを特定し、そのＶＡＬＵＥをＫＥＹとして通信経路を辿る。
