Abstract
(EN)
A tunneling device enabling tunneling without temporarily stopping the network and without altering the configured local network. A frame sorting section (11) judges whether or not a frame inputted from a local network through a physical interface is a capsuled one, outputs the frame to decapsuling means of a tunneling section (13) when the frame is a tunnel one, and outputs the frame to at least one of address solving means of a kernel section (12) and capsuling means of the tunneling section (13) depending on the feature of the frame when the frame is not a tunnel one.
(FR)
La présente invention décrit un dispositif de tunnellisation permettant une tunnellisation sans arrêt temporaire du réseau et sans altération de la configuration du réseau local. Une section de tri de trame (11) définit si une trame saisie depuis un réseau local par le biais d’une interface physique est ou non encapsulée, émet la trame vers un moyen de décapsulation d’une section de tunnellisation (13) lorsque la trame est une trame de tunnel et émet la trame vers au moins un des moyens de résolution d’adresse d’une section kernel (12) et vers un moyen d’encapsulation de la section de tunnellisation (13), selon la nature de la trame lorsque la trame n’est pas une trame de tunnel.

ネットワークを一時停止させず、かつすでに構成されているローカルネットワークに変更を加えることなく、トンネリングを行うことが可能なトンネリング装置を提供する。フレーム振分部11はローカルネットワークから物理インタフェースを通して入力したフレームが、カプセル化されているトンネルフレームであるか否かを判定し、トンネルフレームであるフレームをトンネリング部13のデカプセル化手段へ出力し、トンネルフレームではないフレームを、そのフレームの特徴に基づいてカーネル部12のアドレス解決手段及びトンネリング部13のカプセル化手段の少なくとも一方に出力する。
