Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present application more clear, 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 control packets. Since the UDP protocol is unreliable, in order to ensure that the control packets can be transmitted in a reliable and orderly manner, the prior art solution adopts serial processing. mechanism. For example, when the AC has a set of request packets to send to the AP, the AC first sends the first request packet, and only sends the next request packet after receiving the AP's response packet to the first request packet. , and so on, until a group of request packets are all processed. It can be seen th...

Abstract

The invention provides a controlling method and a controlling device based on UDP (User Datagram Protocol) transmission. The method comprises the steps of: receiving a first request message sent by a sending terminal device, wherein the first request message is any request message in a group of request messages sent by the sending terminal device; judging whether the first request message is a second request message, wherein the second request message is the request message which should be currently received by a receiving terminal device according to sequence of the messages in the group of request messages; when the first request message is not the second request message, interposing the first request message into the corresponding position in a receiving buffer area according to sequence of the messages in the group of request messages; when the first request message is the second request message, sending a first response message of the first request message to the sending terminal device. By the above processing procedure, processing delay of the control message is reduced, and processing efficiency of the control message is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, and 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 performs control message transmission, 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 control message transmission, the prior art solution adopts a serial transmission mode of one sending and one receiving. For example, the AC end sends a request packet, the AP end receives the request packet and then replies with a response packet, and after the AC end receives the response...
