Abstract:
(EN) [Purpose] To stably provide a communication service in a network with dynamically variable link bands. [Solution] A communication system comprises a plurality of packet transfer function units that form a network and a packet transfer control device that controls the packet transfer function units in flow units, wherein, if a change occurs in the communication bandwidth of a link at least one end of which is terminated by the packet transfer function units, band control is applied to flow through the link on the basis of a usability rate associated with the current communication band of the link and flow conditions for flow through the link.
(FR) L'invention vise à fournir, de manière stable, un service de communication dans un réseau ayant des bandes de liaisons à variation dynamique. A cet effet, un système de communication comprend une pluralité d'unités de fonction de transfert de paquet qui forment un réseau et un dispositif de commande de transfert de paquet qui commande les unités de fonction de transfert de paquets dans des unités de flux. Si un changement se produit dans la bande passante de communication d'une liaison dont au moins une extrémité est terminée par les unités de fonction de transfert de paquet, une commande de bande est appliquée pour s'écouler à travers la liaison sur la base d'un taux d'utilisation associé à la bande de liaison de communication actuelle et de conditions d'écoulement pour l'écoulement par la liaison.
(JA) 【課題】動的にリンク帯域が変わりうるネットワークにおいて、安定的に通信サービスを提供する。 【解決手段】ネットワークを構成する複数のパケット転送機能部と、各パケット転送機能部をフロー単位で制御するパケット転送制御装置と、を有する通信システムであって、前記パケット転送機能部が少なくとも一方を終端するリンクの通信帯域に変化が生じた場合、前記リンクの現在の通信帯域に紐づいた可用率と前記リンクを流れるフローのフロー要件とに基づいて、前記リンクに流れるフローに対する帯域制御を実施する。
