Title (EN) ETHERNET FRAME-BASED TRAFFIC CONTROL METHOD
(FR) PROCÉDÉ DE CONTRÔLE DE TRAFIC BASÉ SUR UNE TRAME ETHERNET
(KO) 이더넷 프레임 기반의 트래픽 제어 방법
Abstract:
(EN) The present invention relates to an Ethernet frame-based traffic control method. More specifically, the present invention relates to an Ethernet frame-based traffic control method capable of solving a broadcast storm or a traffic congestion problem that may occur when a high-availability seamless redundancy (HSR)-based network, which is one of high availability network protocols for industrial communication networks, is connected with a spanning-tree protocol/rapid STP (STP/RSTP)-based external network. The present invention comprises: (a) a step in which one node of a plurality of nodes constituting a network transmits an Ethernet frame which has a predetermined structure; (b) a step in which the one node receives an Ethernet frame; and (c) a step in which, after the one node analyzes the received Ethernet frame, the one node changes the state of a port, which is included in the one node and has received the Ethernet frame, according to an analysis result, or transfers the received Ethernet frame to other nodes constituting the network.
(FR) La présente invention concerne un procédé de contrôle de trafic basé sur une trame Ethernet. Plus spécifiquement, la présente invention concerne un procédé de contrôle de trafic basé sur une trame Ethernet et capable de résoudre une tempête de diffusion ou un problème d'encombrement de trafic qui peut se produire lorsqu'un réseau basé sur une redondance continue à haute disponibilité (HSR, "high-availability seameless redundancy"), qui est l'un des protocoles de réseau à haute disponibilité pour des réseaux de communication industriels, est connecté à un réseau externe basé sur un protocole d'arbre maximal (STP, "spanning tree protocol") ou un STP rapide (RSTP, "rapid spanning tree protocol"). La présente invention comprend : a) une étape dans laquelle un nœud d'une pluralité de nœuds constituant un réseau transmet une trame Ethernet qui a une structure prédéterminée ; b) une étape au cours de laquelle ledit nœud reçoit une trame Ethernet ; et c) une étape dans laquelle, après que ledit nœud a analysé la trame Ethernet reçue, ledit nœud change l'état d'un port qui est inclus dans ledit nœud et qui a reçu la trame Ethernet, selon un résultat d'analyse, ou transfère la trame Ethernet reçue à d'autres nœuds constituant le réseau.
(KO) 본 발명은 이더넷 프레임 기반의 트래픽 제어 방법에 관한 것이다. 보다 상세하게는 산업용 통신 네트워크를 위한 고가용성 네트워크 프로토콜 중 하나인 HSR(High-availability Seamless Redundancy) 기반의 네트워크가 STP/RSTP(Spanning-Tree Protocol/Rapid STP) 기반의 외부 네트워크와 연계하는 경우 발생 가능한 브로드캐스트 스톰(broadcast storm) 또는 트래픽 폭주 문제를 해결할 수 있는 이더넷 프레임 기반의 트래픽 제어 방법에 관한 것이다. 본 발명은 (a) 네트워크를 구성하는 복수 개의 노드 중 하나의 노드가 미리 결정된 구조를 갖는 이더넷 프레임을 전송하는 단계; (b) 상기 하나의 노드가 이더넷 프레임을 수신하는 단계; 및 (c) 상기 하나의 노드가 상기 수신된 이더넷 프레임을 분석한 후 상기 분석 결과에 따라 상기 하나의 노드에 포함되며 상기 이더넷 프레임을 수신한 포트의 상태를 변경하거나 또는 상기 수신된 이더넷 프레임을 상기 네트워크를 구성하는 다른 노드들로 전달하는 단계를 포함하는 것을 특징으로 한다.
