Example Embodiment

[0031] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] When transmitting service configuration data for the wireless access device through the controller, the controller can divide the configuration data sent to the wireless access device into sent data and unsent data. For example, two different databases can be used Manage the sent configuration data and the unsent configuration data separately. When the wireless access device is disconnected and reconnects to the controller, the controller only sends the unsent configuration data to the wireless access device. After accessing the confirmation message returned by the device, move the above configuration data from the unsent database to the sent database.

Abstract

The embodiment of the invention relates to a data transmission method. When configuration data of service are transmitted to a wireless access device through a controller, the controller can divide the configuration data sent to the wireless access device into sent data and unsent data, for example, two different databases can be used for separately managing the sent configuration data and the unsent configuration data, and in the case of offline of the wireless access device, when the wireless access device accesses the controller again, the controller only sends the unsent configuration data to the wireless access device. By adoption of the data transmission method provided by the embodiment of the invention, the sent configuration data and the unsent configuration data are distinguished, in the case of re-access of the wireless access device, only the unsent configuration data are sent to the corresponding wireless access device, thereby reducing the waste of wireless resources caused by the repeated sending of the configuration data, and improving the user experience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique [0002] In a data center network, the controller is generally used to manage devices and deploy services. Wherein, the communication between the controller and the device is mostly through a wireless connection, that is, the controller sends the configuration data of the service to the device through the wireless connection. For example, the device can be deployed on a bus, and the controller can send service configuration data to the device deployed on the bus through a wireless connection, so that the device can provide services to passengers on the bus according to the configuration data. [0003] However, in the actual implementation process, due to the instability of the wireless connection, for example, if there is an obstacle blocking the wireless signal, the connection between the device and t...
