Abstract
(EN)
Disclosed is a technique for eliminating wasteful tunneling encapsulation processing when redirecting packets. In said technique, a redirection tunnel (T1) is established between LMA 111 and LMA 112 for redirecting packets from a first connection to a second connection. The first connection uses a first address, for one interface (131) of an MN (130), and is routed through LMA 111 and MAG 121. The second connection uses a second address, for another interface (132) of the MN (130), and is routed through LMA 112 and MAG 122. If MAG 122 knows the first address, packets that are addressed to the first address and were redirected via a tunnel (T) are encapsulated and forwarded to MAG 122 by LMA 112.

L'invention porte sur une technique pour éliminer un traitement d'encapsulation par effet tunnel coûteux lors de la redirection de paquets. Dans ladite technique, un tunnel de redirection (T1) est établi entre LMA 111 et LMA 112 pour rediriger des paquets d'une première connexion vers une seconde connexion. La première connexion utilise une première adresse, pour une interface (131) d'un MN (nœud mobile) (130), et est routée à travers LMA 111 et MAG 121. La seconde connexion utilise une seconde adresse, pour une autre interface (132) du MN (130), et est routée à travers LMA 112 et MAG 122. Si MAG 122 connaît la première adresse, des paquets qui sont adressés à la première adresse et qui ont été redirigés par l'intermédiaire d'un tunnel (T) sont encapsulés et transférés à MAG 122 par LMA 112.

 パケットをリダイレクトする際の無駄なトンネリングカプセル化処理を省略する技術が開示され、その技術によればMN130のインタフェース131の第1のアドレスを使用してLMA111及びMAG121を経由する第1のコネクションのパケットを、MN130のインタフェース132の第2のアドレスを使用してLMA112及びMAG122を経由する第2のコネクションにリダイレクトする場合に、LMA111-LMA112間にリダイレクション用トンネルT1を確立して、LMA112は、MAG122が第1のアドレスを知得している場合にはトンネルT経由でリダイレクトされた第1のアドレスあてパケットをMAG122あてにカプセル化して転送する。
