Abstract:
(EN) [Problem] To provide a packet processing device and the like capable of suppressing output delay of a high-priority packet. [Solution] This packet processing device comprises a plurality of storage units, an on/off switching unit, a collection unit, an analysis unit, and a control unit. The storage units store received packets according to the types of the received packets. The on/off switching unit switches the output of each of the storage units on and off. The collection unit collects packet amounts in the respective time slots of the received packets. The analysis unit identifies periodic patterns in the received packets on the basis of the packet amounts in the respective time slots of the received packets. The control unit identifies, on the basis of the periodic patterns in the received packets identified by the analysis unit, a time slot section in which a predetermined type of received packet is preferentially outputted, and controls the switching on or off of each of the on/off switching units in the identified time slot section.
(FR) [Problème] Fournir un dispositif de traitement de paquets et similaire capable de supprimer le retard de sortie d'un paquet à haute priorité. [Solution] L'invention concerne un dispositif de traitement de paquets qui comprend une pluralité d'unités de stockage, une unité de commutation marche/arrêt, une unité de collecte, une unité d'analyse et une unité de commande. Les unités de stockage stockent des paquets reçus selon les types des paquets reçus. L'unité de commutation marche/arrêt commute la sortie de chacune des unités de stockage dans les états activé et désactivé. L'unité de collecte collecte des quantités de paquets dans les intervalles de temps respectifs des paquets reçus. L'unité d'analyse identifie des motifs périodiques dans les paquets reçus sur la base des quantités de paquets dans les intervalles de temps respectifs des paquets reçus. L'unité de commande identifie, sur la base des motifs périodiques dans les paquets reçus identifiés par l'unité d'analyse, une section d'intervalle de temps dans laquelle un type prédéterminé de paquet reçu est de préférence émis, et commande la commutation marche ou arrêt de chacune des unités de commutation marche/arrêt dans la section d'intervalle de temps identifiée.
(JA) 【課題】高優先パケットの出力遅延を抑制できるパケット処理装置等を提供する。 【解決手段】パケット処理装置は、複数の格納部と、開閉部と、収集部と、解析部と、制御部とを有する。格納部は、受信パケットの種別毎に受信パケットを格納する。開閉部は、各格納部の出力を開閉する。収集部は、受信パケットのタイムスロット毎のパケット量を収集する。解析部は、受信パケットのタイムスロット毎のパケット量に基づき、受信パケットの周期性パターンを特定する。制御部は、前記解析部にて特定された前記受信パケットの周期性パターンに基づき、所定種別の受信パケットを優先的に出力するタイムスロット区間を特定し、特定されたタイムスロット区間の前記各開閉部の開閉を制御する。
