DR DEVICE SELECTION METHOD AND APPARATUS BASED ON OSPF PROTOCOL, AND STORAGE MEDIUM
(FR)
PROCÉDÉ ET APPAREIL DE SÉLECTION DE DISPOSITIF DR SE BASANT SUR UN PROTOCOLE OSPF, ET SUPPORT DE STOCKAGE
(ZH)
基于OSPF协议的选择DR设备的方法及装置、存储介质
Abstract:
(EN)
Disclosed is a DR device selection method based on an OSPF protocol, comprising: taking a designated router determined by means of a designated protocol as a false designated router; instructing the false designated router and each router in a network to determine the shortest path tree by respectively taking themselves as root nodes, and to respectively determine the sum of path loss values thereof according to path loss values of branches of the shortest path tree; and instructing the false designated router to collect relevant information about the sums of path loss values of all the routers in the network, and to select, according to the relevant information about the sums of the path loss values, a designated router and a backup designated router. Further disclosed are a DR device selection apparatus based on an OSPF protocol, and a storage medium.
(FR)
L'invention concerne un procédé de sélection de dispositif DR basé sur un protocole OSPF, comprenant les étapes consistant à : considérer un routeur désigné déterminé au moyen d'un protocole désigné comme étant un routeur désigné faux ; ordonner au routeur désigné faux et à chaque routeur dans un réseau de déterminer l'arbre de chemin le plus court en se considérant respectivement comme des nœuds racines, et de déterminer respectivement la somme des valeurs de perte de trajet de celui-ci en fonction de valeurs de perte de trajet de branches de l'arbre de trajet le plus court ; et ordonner au routeur désigné faux de collecter des informations pertinentes concernant les sommes de valeurs de perte de trajet de tous les routeurs dans le réseau, et de sélectionner, en fonction des informations pertinentes concernant les sommes des valeurs de perte de trajet, un routeur désigné et un routeur désigné de sauvegarde. L'invention concerne en outre un appareil de sélection de dispositif DR basé sur un protocole OSPF, et un support de stockage.
(ZH)
一种基于OSPF协议的选择DR设备的方法,包括:将通过指定协议确定的指定路由设备作为伪指定路由设备;指示所述伪指定路由设备及网络中各路由设备分别以自己作为根节点确定最短路径树,根据所述最短路径树的各个枝干的路径损耗值分别确定各自的路径损耗值之和;指示所述伪指定路由设备收集网络中所有路由设备的路径损耗值之和的相关信息,根据路径损耗值之和的相关信息选举指定路由设备和备份指定路由设备。一种基于OSPF协议的选择DR设备的装置、存储介质。
