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 CAPWAP tunnel data package transmission. The method and the device are used for solving the problem that an existing AP is low in data processing efficiency. The method for CAPWAP tunnel data package transmission includes the steps that parameter information of all data packages is determined by a transmitting end; according to the determined parameter information of all the data packages, the data packages needing to be sliced are selected from all the data packages; the selected data packages are sliced to obtain multiple new data packages; the new data packages are packaged, and the new packaged data packages are transmitted. According to the technical scheme, as only the data packages needing to be sliced are sliced in a driving layer, the problem that in the prior art, the AP needs to consume a great number of resources in the data transmission process is avoided, and therefore the efficiency of processing the data packages is improved.

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 gradually passes through AC (Wireless Access Controller) and AP between CAPWAP tunnel transmission, but because the transmission link MTU (Maximum Transmission Unit, maximum transmission unit) between AP and AC is generally 1500 bytes, and the MTU of general Ethernet is also 1500 bytes, so 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 th...
