Embodiment Construction

[0116] The sending end of the embodiment of the present invention determines the parameter information of each data packet, selects the data packets that need to be fragmented from all the data packets according to the determined parameter information of each data packet, and fragments the selected data packets processing to obtain a plurality of new data packets, and then perform encapsulation processing on the new data packets, and send the encapsulated new data packets. This technical solution only needs to perform fragmentation processing on the data packets that need to be fragmented at the driver layer, avoiding the problem that the AP needs to consume a large amount of resources in the process of data transmission in the prior art, thereby improving the efficiency of the data packets. Processing efficiency.

[0117] In the embodiment of the present invention, the receiving end decapsulates the outer layer information of the data packet received from the sending end to o...

Abstract

The invention relates to the technical field of wireless communication, in particular to a method and device for transmitting CAPWAP tunnel data packets, which are used to solve the problem of low data processing efficiency of current APs. The method for transmitting CAPWAP tunnel data packets in the embodiment of the present invention includes: the sending end determines the parameter information of each data packet, selects the data packets that need to be fragmented from all the data packets according to the determined parameter information of each data packet, and The selected data packets are fragmented to obtain multiple new data packets, and then the new data packets are encapsulated, and the encapsulated new data packets are sent. This technical solution only needs to perform fragmentation processing on the data packets that need to be fragmented at the driver layer, avoiding the problem that the AP needs to consume a large amount of resources in the process of data transmission in the prior art, thereby improving the efficiency of the data packets. Processing efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for transmitting CAPWAP tunnel data packets. Background technique [0002] With the large-scale use of thin AP (Wireless Access Point, wireless access point) architecture network based on CAPWAP (Control And Provisioning of Wireless Access Points Protocol Specification, wireless access point control and configuration protocol), user online data is gradually passed through AC ( CAPWAP tunnel transmission between the wireless access controller) and the AP, but because the MTU (Maximum Transmission Unit) of the transmission link between the AP and the AC is generally 1500 bytes, and the MTU of the general Ethernet is also 1500 Bytes, this will cause the CAPWAP packet after encapsulating the user packet to be larger than the MTU of the transmission link between the AP and the AC. [0003] In the prior art, the carried CAPWAP message is fragmented t...
