Abstract
(EN)
[Problem] To perform switching of a mirror port without packet loss. [Solution] An information processing device 101 receives, by means of a virtual switch 113, a mirror switching instruction that specifies a transition source port and a transition destination port. When the mirror switching instruction is received by means of the virtual switch 113, the information processing device 101 receives a first mirror switching notification for a virtual switch 122 having the transition destination port, and cancels, in the transition source port, a mirror setting for a packet transmitted to the transition destination port. When a second mirror switching notification from the virtual switch 122 is received by means of the virtual switch 113, the information processing device 101 cancels, in the transition source port, a mirror setting for a packet received from the transition destination port.

Le problème décrit par la présente invention est de réaliser une commutation d'un miroir de port sans perte de paquet. La solution de l'invention concerne un dispositif de traitement d'informations (101) qui reçoit, au moyen d'un commutateur virtuel (113), une instruction de commutation de miroir qui spécifie un port de source de transition et un port de destination de transition. Lorsque l'instruction de commutation de miroir est reçue au moyen du commutateur virtuel (113), le dispositif de traitement d'informations (101) reçoit une première notification de commutation de miroir pour un commutateur virtuel (122) présentant le port de destination de transition, et annule, dans le port de source de transition, un réglage de miroir pour un paquet transmis au port de destination de transition. Lorsqu'une seconde notification de commutation de miroir provenant du commutateur virtuel (122) est reçue au moyen du commutateur virtuel (113), le dispositif de traitement d'informations (101) annule, dans le port de source de transition, un réglage de miroir pour un paquet reçu de la part du port de destination de transition.

【課題】パケットをロスすることなくミラーポートの切り替えを行うこと。 【解決手段】情報処理装置101は、仮想スイッチ113により、移行元ポートと移行先ポートとを特定するミラー切替指示を受け付ける。情報処理装置101は、仮想スイッチ113により、ミラー切替指示を受け付けたことに応じて、移行先ポートを有する仮想スイッチ122に対する第1ミラー切替通知を送信するとともに、移行元ポートにおける移行先ポートへの送信パケットのミラー設定を解除する。情報処理装置101は、仮想スイッチ113により、仮想スイッチ122からの第2ミラー切替通知を受け付けたことに応じて、移行元ポートにおける移行先ポートからの受信パケットのミラー設定を解除する。
