摘要： Embodiments of the present invention provide a control device, a system, and a transmission channel control method in SDN. According to technical solutions provided in the embodiments of the present invention, a connection status of a control channel is acquired, it is determined, according to a preset threshold, whether a standby channel is suitable to continue serving as a standby channel; when the standby channel is congested to a specific extent, the standby channel is adjusted and another uncongested channel is set as a standby channel; and when an active channel is congested, the standby channel is switched to an active channel, so that real-time channel adjustment is ensured, effective transmission of control information is ensured, and control reliability of a control device in SDN is improved.

摘要： Embodiments of the present invention disclose a topology stratification method and apparatus, and a flooding processing method and apparatus. The method includes the following: First, a controller receives a data packet that is reported by a switch connected to a source host; then the controller searches a local MAC address table of physical addresses of devices to determine whether a destination address of the data packet exists, and the controller acquires a destination port if no destination address of the data packet exists, where the destination port is a port of a switch connected to a destination host, and the destination host is another host different from the source host; and finally, the controller uses the destination port as a destination address to generate a routing table, and sends the routing table to the switch connected to the source host, so that the switch connected to the source host forwards the data packet according to the routing table. The present invention is applicable to the field of communications systems.

摘要： The present invention provides a method for constructing a multipath forwarding rule, an apparatus, and a system. A controller invokes a multipath algorithm to generate multiple paths for a data stream; the controller generates a multiport rule of each forwarding device according to the multiple paths; the controller generates metadata according to the multiport rule of each forwarding device, where the metadata includes information for indicating at least one forwarding port of the forwarding device; the controller generates a flow entry establishment indication; the controller sends the flow entry establishment indication to each forwarding device, so that each forwarding device selects the at least one forwarding port of the forwarding device according to the metadata and according to the flow entry establishment indication, to forward the data stream. Because a forwarding device may reuse a port combination according to metadata, after generating a flow entry, a controller does not need to query an already used group, and directly sends the flow entry to each forwarding device, thereby shortening a decision time of the controller.
摘要翻译：本发明提供了一种构建多路径转发规则的方法，装置和系统。控制器调用多路径算法为数据流生成多条路径; 控制器根据多路径生成每个转发设备的多端口规则; 所述控制器根据每个转发设备的多端口规则生成元数据，所述元数据包括用于指示所述转发设备的至少一个转发端口的信息; 控制器生成流表项建立指示; 控制器向每个转发设备发送流表项建立指示，以便每个转发设备根据元数据并根据流表项建立指示选择转发设备的至少一个转发端口转发数据流。由于转发设备可以根据元数据重用端口组合，因此控制器在生成流表项后不需要查询已经使用过的组，并直接将流表项发送给每个转发设备，从而缩短了控制器的决策时间。
