Embodiments of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] The purpose of the embodiment of the present invention is to solve the problem that in the prior art, because multiple people use the same access point, such as an access point, the access point may be overloaded, because the access point is It is necessary to use the protocol stack to perform layer-by-layer forwarding of data packets, which will occupy a large amount of system resources. After receiving data, it needs to be unpacked, and a data packet needs to be packetized, which wastes a lot of system resources, thereby causing network data congestion. Speed requirements that affect the normal use of the user. The invention will now be described in detail with reference to the accompanying drawings.

[0041] Embodiment 1:

1 shows an implementation flow of a port data separation method according to a first embodiment of the present invention, which is described in detail below.

[0043] In step S101, after receiving the data sent by the downlink port, the protocol stack packet process is ignored, and after the data is sent to the upper layer network, the corresponding virtual local area network identifier vlan id is determined according to the received data, and Add the data to the virtual local area network identifier vlanid. [0044] Specifically, the data sent by the receiving downlink port in the embodiment of the present invention refers to an access point, such as a routing device such as a 痩 access point. The lower-link port is the one that is close to the user side in the network, and the one that is close to the server in the network is the upper-layer network described in the embodiment of the present invention.

[0045] The packet flow process of the protocol stack refers to that the protocol stack layer-by-layers data according to the protocol layer, that is, data enters each protocol stack layer, and adds header information to the data according to the protocol of the layer. In the embodiment of the present invention, the protocol stack packet process is neglected, and the identification information of the packet may be implemented by modifying the data. Of course, the triggering of the packet instruction may be performed by other means, so that the protocol stack packet process is ignored.

[0046] After ignoring the packet process, the data is sent to the upper layer network, and the virtual local area network identifier vlanid corresponding to the data is obtained according to the identification information in the data, and the virtual local area network identifier vlanid is added to the data, thereby The data including the identification can be accurately transmitted to the target location, and the packetizing operation on the data can be reduced.

[0047] In step S102, after receiving the data transmitted by the upper layer network, the received data is parsed to obtain a virtual local area network identifier vlanid, and the data is forwarded to the corresponding port according to the virtual local area network identifier vlanid.

[0048] After receiving the data sent by the upper layer network, the target location of the data needs to be parsed. The present invention parses the virtual local area network identifier vlanid according to the received data, according to the preset correspondence between the virtual local area network identifier and the port. , thereby forwarding data to the corresponding port.

[0049] For example, the source physical MAC address and the network card device name may be obtained according to the data analysis, and according to the network card device name and the source physical MAC address, combined with the preset correspondence, the port corresponding to the data may be obtained, thereby separating the data.

[0050] In the embodiment of the present invention, after receiving the data of the downlink port, the packet flow of the protocol stack is ignored, and after the data is sent to the upper layer network, the corresponding virtual local area network identifier is determined according to the data, and the virtual data is added to the data. The network identifier, after receiving the data of the upper layer network, parses the received data to obtain a virtual local area network identifier, and forwards the data to the corresponding port according to the virtual local area network identifier, thereby avoiding data entry into the protocol stack packet and unpacking operation. Improve the processing efficiency of data, reduce the consumption of system resources, and thus better adapt to the requirements of multi-user peer use.

[0051] Embodiment 2: [0052] FIG. 2 is a flowchart showing an implementation process of determining a corresponding virtual local area network identifier vlanid according to the received data according to the second embodiment of the present invention. On the basis of the first embodiment, the specific step is described as follows: In step S201, the source MAC address and the source network card device name are extracted in the received data.

[0054] Specifically, the source MAC address and the source network card device name are extracted in the received data, and the add_vlan code may be added in the NIC interface egress module, and the source mac address field and the source NIC device name field are extracted in the data part of the sk_buff. The sk_buff is the most important structure of the TCP/IP protocol stack. It is the representation of the network datagram in the kernel. The corresponding source mac address and the source network card device name information can be extracted in the data data part.

[0055] In step S202, it is determined whether the source network card device name is the same as the preset network card device name.

[0056] In the embodiment of the present invention, the name of the wired network card device is preset. For example, the preset network card device name may be Ethl, and then the cable network port identification can be quickly performed by comparing the network card device names. .

[0057] In step S203, if the source network card device name and the preset network card device name are the same, the virtual local area network identifier vlanid is a wired interface virtual local area network identifier vlanid.

[0058] Since all the names of the wired network cards are set in advance, if the network card device name is identified as the preset name, the wired network port can be quickly identified.

[0059] By identifying the name of the wired network card, it is possible to overcome the problem of difficulty in identifying wired users and wireless users in the prior art. In the prior art, the data of the wired port and the wireless port connected to the access point are uniformly forwarded, which also brings a lot of inconvenience to the management. If we want to extract the wireless user, it must be from the user list. Eliminate wired users to gain wireless users. Furthermore, today's fitAP devices generally have at least one wireless access point, most of which are concentrated between 2-10 wireless access points, thus separating different access points. Users are even harder. However, the invention can quickly identify the wired interface by using the name of the network card device.

[0060] For example, if the default source network card device name is Ethl, and the network card device name of the device is Ethl, the interface may be determined as the wired interface Ethl vlanic according to the network card device name.

[0061] In step S204, if the source network card device name and the preset network card device name are different, the corresponding wireless interface is searched according to the source MAC address, and the corresponding virtual local area network identifier vlanid is determined according to the wireless interface. [0062] If the network card device name is different from the preset network card device name, the current interface is a wireless interface, and the virtual local area network identifier of the wireless interface is further determined according to the correspondence between the source mac address and the virtual local area network identifier vlanid. Vlanid. That is, different source mac addresses correspond to different virtual local area network identifiers vlanid. Thereby different wireless interfaces can be distinguished.

[0063] The step of distinguishing the virtual local area network identifier vlanid of the wired interface and the virtual local area network identifier vlanid of the different wireless interfaces further includes the steps of further adding data to the virtual local area network identifier vlanid, including:

[0064] in the data storage area, the data is moved backward, and the structure control header space is obtained before the data storage location of the data storage area; the structure control header space is zeroed and the corresponding virtual local area network identifier is written. Vlanid°

[0065] The data area can be pushed backward by the skb_push command, and the head storage space is added for adding the vlan_ethhdr structure. After the _V l _an _ethhd _r structure control header is cleared, the corresponding virtual local area network identifier vlanid is written into the h_vlan_TCI element. The virtual LAN ID vlanid can be added to the data.

Corresponding to step S102 in the first embodiment, when receiving the data sent by the upper layer network, parsing the received data to obtain a virtual local area network identifier vlanid, and forwarding the data according to the virtual local area network identifier vlanid The steps to the corresponding port include:

[0067] When receiving data sent by the upper layer network, parsing the structure control header of the data, obtaining a network interface corresponding to the data; and transmitting the data to a corresponding network interface.

[0068] corresponding to the addition of the virtual local area network identifier vlanid, after parsing the received data, according to the structure of the structure control header, adding a _re m _0ve _vl _an code to the network card interface access, when the network device portal receives the data packet吋, first extract the structure data of the structure control header, and determine which network interface, such as a wired network interface and a specific wireless network interface, is sent to the corresponding network interface according to the virtual local area network identifier vlanid in the extracted data.

[0069] On the basis of the first embodiment, the embodiment of the present invention further distinguishes the wired network interface data from the wireless network interface data and the different wireless network interface data, and effectively reduces the system resource consumption of the network device. , also improves the convenience of data differentiation.
