Zusammenfassung: | PROBLEM TO BE SOLVED: To improve the imbalance of transmission amounts among communication paths in a communication network with a network configuration having the plurality of paths to an object node by using a communication protocol which does not allow traffic to be divided (such as UDP).SOLUTION: A relay device includes: a flow information holding memory 205 associates and stores information to uniquely identify a flow from traffic per path with protocol information, a transmission destination port number, and a transmission amount; a flow distribution unit B203 for determining a transmission destination device on the basis of information in the memory and information in the header per constant time; and a flow measurement unit 204 for measuring a transmission amount per path per constant time. A transmission/reception unit 206 distributes the flow to the transmission destination determined by the flow distribution unit B203 on the basis of the measurement result by the flow measurement unit 204.SELECTED DRAWING: Figure 2
【課題】分割不可の通信プロトコルを使用(UDPなど)し、目的ノードまでの経路が複数あるネットワーク構成の通信ネットワークにおける、通信経路間の送信量の偏りの改善。【解決手段】中継装置は、経路ごとにトラヒックからフローを一意に特定するための情報とプロトコル情報、送信先ポート番号、送信量とを対応付けて格納するフロー情報保持メモリ205と、一定時間ごとに前記メモリの情報と当該ヘッダの情報とに基づいて伝送先装置を判定するフロー振り分け部B203と、一定時間ごとに経路ごとの送信量を測定するフロー測定部204を有する。フロー測定部204の測定結果に基づいて、フロー振り分け部B203が判定した転送先に送受信部206がフローを分散する。【選択図】 図2 |
