Abstract:
(EN) An information processing device (100) includes a virtual MAC management table storage unit (13a) which stores virtual MAC addresses of VNFs (10) set for respective access devices (60) managed by the VNFs (10). When the VNFs (10) each receive a frame, the information processing device (100) causes each of the VNFs (10) to determine whether the transmission destination MAC address of said frame matches any of the virtual MAC addresses of the VNF (10), and performs control to cause a VNF (10) having no virtual MAC address that matches the transmission destination MAC address to discard the frame. Furthermore, the information processing device (100) performs control to cause a VNF (10) having a virtual MAC address that matches the transmission destination MAC address to monitor communication of the corresponding access device (60) on the basis of information included in the frame.
(FR) L'invention concerne un dispositif de traitement d'informations (100) comprenant une unité de stockage de table de gestion MAC virtuelle (13a) qui stocke des ensembles d'adresses MAC virtuelles de VNF (10) pour des dispositifs d'accès (60) respectifs gérés par les VNF (10). Lorsque les VNF (10) reçoivent chacune une trame, le dispositif de traitement d'informations (100) amène chacune des VNF (10) à déterminer si l'adresse MAC destinataire de transmission de ladite trame coïncide ou non avec l'une quelconque des adresses MAC virtuelles de la VNF (10), et effectue une commande pour amener une VNF (10) ne possédant pas d'adresse MAC virtuelle qui correspond à l'adresse MAC destinataire de transmission à éliminer la trame. De plus, le dispositif de traitement d'informations (100) exécute une commande pour amener une VNF (10) possédant une adresse MAC virtuelle qui correspond à l'adresse MAC destinataire de transmission à surveiller la communication du dispositif d'accès (60) correspondant sur la base d'informations incluses dans la trame.
(JA) 情報処理装置(100)は、各VNF(10)が管理するアクセス装置(60)ごとにそれぞれ設定されたVNF(10)自身の仮想MACアドレスを記憶する仮想MAC管理テーブル記憶部(13a)を有する。そして、情報処理装置(100)は、各VNF(10)がフレームを受信した場合に、該フレームの送信先MACアドレスが自VNF(10)の仮想MACアドレスのいずれかと一致するか各VNF(10)にそれぞれ判定させ、送信先MACアドレスと仮想MACアドレスとが一致しないVNF(10)については、フレームを破棄させるように制御する。また、情報処理装置(100)は、送信先MACアドレスと仮想MACアドレスとが一致するVNF(10)については、フレームに含まれる情報を基にアクセス装置(60)の通信を監視させるように制御する。
