Abstract
(EN) Disclosed are information notification, message forwarding, and message cancellation methods and apparatuses, a device, and a medium. The information notification method comprises: when constructing a specific topology, associating a specific topology identifier with a BIER forwarding plane; and notifying the network of bit indexed explicit replication BIER information, the BIER information carrying the specific topology identifier, and the BIER information being used by a node in the network for generating a BIER forwarding entry corresponding to the specific topology.
(FR) L'invention concerne des procédés et des appareils de notification d'informations, de transfert de messages et d'annulation de messages, ainsi qu'un dispositif et un support. Le procédé de notification d'informations consiste à : lors de la construction d'une topologie spécifique, associer un identifiant de topologie spécifique à un plan de transfert BIER ; et notifier des informations BIER (réplication explicite d’indice de bit) au réseau, les informations BIER comportant l'identifiant de topologie spécifique, et les informations BIER étant utilisées par un nœud dans le réseau pour générer une entrée de transfert BIER correspondant à la topologie spécifique.
(ZH) 本文公开一种信息通告、报文转发、报文消除方法、装置、设备和介质。信息通告方法,包括:在构建特定拓扑时的情况下,将特定拓扑标识与BIER转发平面进行关联;向网络中通告位索引显式复制BIER信息;其中,所述BIER信息中携带所述特定拓扑标识,所述BIER信息用于所述网络中的节点生成与所述特定拓扑对应的BIER转发表项。
