Abstract
(EN) Provided in an embodiment of the present invention are an information transmission method, device and communication system, the information transmission method comprising: a controller transmits a forwarding instruction to a transponder, the forwarding instruction comprising at least two routing association relationships and a tunnel association relationship, the at least two routing association relationships comprising a first routing association relationship and a second routing association relationship, the first routing association relationship being the mapping of a first route to a next hop identifier, the second routing association relationship being the mapping of a second route to the next hop identifier, the first route being different from the second route, and the tunnel association relationship being the association relationship between the next hop identifier and a public network tunnel. The embodiment of the present invention solves the problem that the OpenFlow standard of an SDN dos not specify an issuing form for the forwarding instruction from a control plane to a forwarding plane.
(FR) Conformément à un mode de réalisation, la présente invention concerne un procédé de transmission d'informations, un dispositif et un système de communication, le procédé de transmission d'informations comprenant les opérations suivantes : un dispositif de commande transmet une instruction de transfert à un transpondeur, l'instruction de transfert comprenant au moins deux relations d'association de routage et une relation d'association de tunnel, les au moins deux relations d'association de routage comprenant une première relation d'association de routage et une seconde relation d'association de routage, la première relation d'association de routage étant le mappage d'une première route à un identificateur de saut suivant, la seconde relation d'association de routage étant le mappage d'une seconde route à l'identificateur de saut suivant, la première route étant différente de la seconde route, et la relation d'association de tunnel étant la relation d'association entre l'identificateur de saut suivant et un tunnel de réseau public. Le mode de réalisation de la présente invention résout le problème selon lequel la norme OpenFlow d'un SDN ne spécifie pas un formulaire de délivrance pour l'instruction de transfert d'un plan de commande à un plan de transfert.
(ZH) 本发明实施例提供一种信息发送方法、装置及通信系统。本发明信息发送方法,包括:控制器向转发器发送转发指示消息,所述转发指示消息包括至少两个路由对应关系和隧道对应关系,所述至少两个路由对应关系包括第一路由对应关系和第二路由对应关系,其中,所述第一路由对应关系为第一路由到下一跳标识的映射,所述第二路由对应关系为第二路由到所述下一跳标识的映射,所述第一路由异于所述第二路由,所述隧道对应关系为所述下一跳标识到公网隧道的对应关系。本发明实施例解决SDN的OpenFlow标准中没有明确规定控制平面到转发平面的转发指示消息下发形式的问题。
