Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] figure 1 Shown is a schematic diagram of a typical wireless network. The AC and AP can communicate based on the CAPWAP protocol. When communicating based on this protocol, the UDP protocol is usually used to transmit the control message. Since the UDP protocol is unreliable, in order to ensure that the control message can be transmitted reliably and orderly, the existing technical solution adopts serial processing mechanism. For example, when the AC has a group of request packets to send to the AP, the AC sends the first request packet first, and the AC sends the next request packet only after receiving the AP’s response packet to the first request packet. , and so on, until a set of request packets are all processed. It can be seen t...

Abstract

The present application provides a control method and device based on UDP transmission. The method includes: receiving a first request message sent by an originating device, where the first request message is one of a group of request messages sent by the originating device. Any request message; judging whether the first request message is a second request message, and the second request message is that the receiving device currently responds according to the sequence of messages in the group of request messages Received request message; when the first request message is not the second request message, send the first request message according to the order of the first request message in the group of request messages Insert the first request message into the corresponding position of the receiving buffer; when the first request message is the second request message, send the first response message of the first request message to the originating device . Through the above processing process, the processing delay of the control message is reduced, and the processing efficiency of the control message is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for processing control messages based on UDP transmission. Background technique [0002] In the networking of AC (Access Controller, access controller) and AP (Access Point, access point), CAPWAP (Control And Provisioning of Wireless Access Point, wireless access point control and configuration) is used between AC and AP The protocol transmits the control message, and the transmission of the protocol is based on the unreliable UDP (User Datagram Protocol, User Datagram Protocol) protocol. [0003] In order to ensure the reliability of the transmission of the control message, the prior art solution adopts a serial transmission mode of sending and receiving. For example, the AC sends a request packet, the AP replies with a response packet after receiving the request packet, and the AC starts to send the next request packet after receiving the resp...
