Abstract: An example apparatus includes at least one processor and at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to: obtain map data at a current moment, where the map data includes a first road area at the current moment, the special road condition is located in the first road area, the first road area is obtained based on a road condition model and a vehicle parameter within a preset time period before the current moment, and the road condition model represents a correspondence between a feature of the vehicle parameter and the special road condition; and determine, based on a planned route of a vehicle, that a second road area exists in the planned route of the vehicle, where the second road area is in the first road area.

Abstract: The application provide an information sending method which includes: sending, by a controller, a forwarding indication message to a forwarder, where: the forwarding indication message includes at least two routing correspondences and a tunnel correspondence, the at least two routing correspondences include a first routing correspondence and a second routing correspondence, the first routing correspondence is mapping of a first route to a next hop identifier, the second routing correspondence is mapping of a second route to the next hop identifier, and the first route is different from the second route; and the tunnel correspondence is a correspondence of the next hop identifier to a public network tunnel. The embodiments of the application resolve a problem that a delivering form of a forwarding indication message that is from a control plane to a forwarding plane is not explicitly stipulated in an OpenFlow standard of an SDN.

Abstract translation: 该应用提供一种信息发送方法，包括：由控制器向转发器发送转发指示消息，其中：所述转发指示消息包括至少两个路由对应和隧道对应，所述至少两个路由对应包括第一 路由对应和第二路由对应，第一路由对应是第一路由到下一跳标识符的映射，第二路由对应是第二路由到下一跳标识符的映射，并且第一路由与第二路由不同 ; 并且隧道对应关系是下一跳标识符与公共网络隧道的对应关系。 该应用的实施例解决了在SDN的OpenFlow标准中没有明确规定从控制平面到转发平面的转发指示消息的传递形式的问题。
