Title
(EN) Information transmission method and device, and communication system
(ZH) 信息发送方法、装置及通信系统
Abstract
(EN) The embodiment of the invention provides an information transmission method and device, and a communication system. The method comprises the step that a controller transmits transfer indication information to a repeater, wherein the transfer indication information comprises at least two router corresponding relations and a channel corresponding relation. The router corresponding relations comprises a first router corresponding relation and a second router corresponding relation, wherein the first router corresponding relation is the mapping from a first router to a next jump identification, and the second router corresponding relation is the mapping from a second router to a next jump identification. The first router is different from the second router. The channel corresponding relation is the corresponding relation from the next jump identification to a public network tunnel. According to the embodiment of the invention, the method and device solves a problem that the transmission mode of transfer indication information from a control plane to a transfer plane is not clearly specified in OpenFlow standard of SDN.
(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。
