Embodiment 7

[0122] Such as Figure 2b As shown, the method for processing downlink service data in Embodiment 7 of the present invention includes:

[0123] Step 500, after the data driver 2 receives the CAPWAP-encapsulated CAPWAP packet sent by the AC through the tunnel, the CAPWAP packet is intercepted by the hook.

[0124] Step 501, the hook judges whether it is a CAPWAP packet that needs to be processed by the local machine, if so, execute step 502; otherwise, execute step 506.

[0125] Step 502, the kernel protocol stack modifies the UDP protocol in the IP header of the CAPWAP packet to the CAPWAP protocol.

[0126] In step 503, the TCP layer unpacks the modified CAPWAP packet to obtain the original service data, and then sends the original service data to the virtual driver.

[0127] Step 504, after the virtual driver receives the original service data through the virtual network port, it sends the original service data to the data driver 2 through the network bridge.

[0128] Ste...

Embodiment 9

[0156] Such as image 3 As shown, the device for processing CAPWAP uplink data in Embodiment 9 of the present invention includes:

[0157] An encapsulation unit 700, configured to perform CAPWAP encapsulation on the uplink data to form a CAPWAP packet when the uplink data enters the virtual drive;

[0158] The sending unit 701 is configured to send the CAPWAP packet to the AC through routing according to the IP address.

[0159] Preferably, the packaging unit 700 is also used for:

[0160] If the uplink data is service data, after receiving the service data through the data driver, if the media access control MAC address of the service data is not a local MAC address, forward it to the virtual driver through the network bridge.

[0161] Preferably, the packaging unit 700 is also used for:

[0162] If the uplink data is management data, then send the management data to the virtual driver through the application layer.

[0163] Preferably, the sending unit 701 is specificall...

Abstract

The invention provides a processing method and device of CAPWAP data. The problem that in the prior art, according to a CAPWAP protocol achieving mode on an application layer, handling capacity is lowered, and CPU occupying rate is improved is solved. The method comprises the steps that when uplink data enter a virtual driver, the uplink data are subjected to CAPWAP packaging, and a CAPWAP package is formed; and according to an IP address, the package is sent to corresponding AC through a route; after downlink data enter an inner core protocol stack, a UDP protocol in an IP head is modified into a CAPWAP protocol, the data enter a TCP layer for unpacking, and downlink data are obtained and are sent through the virtual driver. CAPWAP packaging is achieved in the virtual driver, CAPWAP unpacking is achieved on the TCP layer of the inner core protocol stack, the virtual driver can carry out multiplexing on the subpackaging and burstification functions of an IP layer of the inner core stack protocol, accordingly, the occupying rate of a CPU is lowered, and handling capacity is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for processing CAPWAP data. Background technique [0002] CAPWAP (Control And Provisioning of Wireless Access Points Protocol Specification, wireless access point control and specification) protocol is a general tunneling protocol, which realizes AC (Access Controller, access controller) to AP (Access Point, access point) to perform basic protocol functions such as management, configuration, and business data management. In the WLAN (Wireless Local Area Networks, wireless local area network) network, the data of APs is very large, and the centralized management of ACs on APs is particularly important. All major manufacturers have produced ACs and APs (thin APs) that can perform centralized management. Realized the respective CAPWAP protocol encapsulation functions and additional functions on the protocol encapsulation. Therefore, the decouplin...
