Abstract: The present application relates to the field of display technology and, in particular, to a display module and a display device. The display module comprises a backplane comprising a bottom plate and a side frame disposed on the bottom plate; a display assembly located in the side frame, the display assembly comprising a light source; a support member located on a side frame away from the bottom plate, where the support member is detachably connected to the side frame; and a cover plate located on the side of the support member facing away from the side frame, and the cover plate being bonded to the support member. This solution can solve the problem that the module is difficult to disassemble, so as to reduce the maintenance cost.

Abstract: The present disclosure provides an SDN-based QoS-supported communication tunnel establishment method and system used in a communication network comprising SDN switches and an SDN controller, the method comprising: an SDN switch reports a target MAC address and an SDN flow mismatching a flow table to an SDN controller; the SDN controller obtains a forwarding path of the SDN flow; the SDN controller generates a tunnel ID mapping table and a queue ID mapping table according to the forwarding path and 5-tuple information of the SDN flow, and generates a corresponding flow table, a priority queue being specified in the tunnel ID; the SDN controller dispatches the flow table to the SDN switches; and the SDN switch obtains the output queue and the output port disclosure
