Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the related art, after a client device is connected to a wireless network shared by a host device through a hotspot, due to the limitation of the current mainstream operating system (for example, android or iOS), the operating system running in the host device cannot provide a related interface for an application program, and the traffic data of the client device can only be automatically sent from a default network outlet of the host device to the internet according to the system configuration, so that some application programs associated with the client device cannot contact and interfere with the network traffic of the client device, thereby limiting the function implementation of the client device and the application programs.

Based on this, the method, the device, the system and the electronic device for processing traffic data provided by the embodiments of the present invention may be applied to a scenario in which a client device accesses the internet through a host device when the host device is in communication connection with the client device, for example, when the client device is a host device for a game, the host device may be a terminal device, and the terminal device processes traffic data of the host device.

For the convenience of understanding the present embodiment, first, a hardware scenario of a traffic data processing method disclosed in the present embodiment is described, as shown in fig. 1, where a first device is communicatively connected to an external network; the first device is also connected with network card equipment; the network card equipment is used for establishing a wireless network; the first device is in communication connection with the second device through a wireless network established by the network card device, wherein the first device is the host device, the second device is the client device, the external network generally refers to a data communication network outside the wireless network established by the network card device, and the external network is provided with a specified flow data transmission path and a network server.

Then, a detailed description is made of a method for processing flow data disclosed in the embodiment of the present invention, as shown in fig. 2, where the method is applied to a first device; the first device is in communication connection with an external network; the first device is also connected with network card equipment; the network card equipment is used for establishing a wireless network; the first device is in communication connection with the second device through a wireless network established by the network card device. The processing method of the flow data comprises the following steps:

step S202, receiving first flow data sent by second equipment through network card equipment;

the network card is a computer hardware device designed to allow intelligent devices such as mobile phones, tablets, computers and the like to communicate on a computer network, and is divided into a wired network card and a wireless network card, wherein the wireless network card can be divided into a USB (universal serial bus), a PCI (Component Interconnect, peripheral component interconnect standard), a PCI-E (Peripheral Component Interconnect-express, high-speed serial bus) interface and the like according to the interface type of the interface with the intelligent devices. In this embodiment, the network card device may be a USB (Universal Serial BUS ) wireless network card. Here, the USB network card device is designed with different hardware facilities according to the difference of running an operating system in the intelligent device to which it is connected, for example: aiming at the Android operating system, the network card equipment main control chip can use a USB network card chip disclosed in the industry, and the chip can support hot spot network establishment of a 5Ghz frequency band; for the iOS operating system, the USB network card must include an MFi dedicated chip provided by apple. After the network card device is connected with the intelligent device through the network card interface, an operating system of the intelligent device can not only call a corresponding network card driving program to drive the network card to enable the device to be networked, but also enable other intelligent devices to be connected with the Internet through establishing a hot spot in a mode of connecting a hot spot network. In actual implementation, the second device may be a game host device, and the first device has an application program associated with the game host device running therein. After the first equipment is networked through the network card equipment and establishes communication connection between the wireless network and the second equipment, the second equipment can transmit flow data to the first equipment through the wireless network, and the first equipment and a network communication interface of an external network are utilized for transmitting and receiving data flow so as to realize network communication.

In this step, after the first device and the second device implement network communication, the first device may receive, through the network card device, first traffic data sent by the second device, where the first traffic may include: target traffic requiring special handling and normal traffic not requiring special handling.

Step S204, identifying a target flow from the first flow data based on a preset flow processing rule;

the target flow rate is a flow rate marked with specific use and specific information, for example: the game traffic used to accelerate the designated game is marked with the designated traffic destination network address, binding information of domain name and host, etc. The traffic processing rule is a basis for screening the target traffic from the first traffic data, and includes traffic screening information, where the traffic screening information may be a traffic destination network address, binding information between a domain name and a host, and the like.

After receiving the first flow data sent by the second device through the network card device, the first device screens out flow data matching flow screening information in the flow processing rule from the first flow according to a preset flow processing rule, and determines the flow data as a target flow.

In this step, the target flow in the first flow is distinguished from the normal flow according to a preset flow processing rule, which is a precondition for the subsequent special processing of the target flow data.

Step S206, carrying the preset sending path into the target flow, and sending the target flow to the external network so as to send the target flow according to the sending path through the external network.

After screening out the target flow, before the target flow is sent to an external network, the target flow is packaged according to actual requirements, and intervention on the flow data is realized. For example: and designating the network address of the proxy server on the target traffic data carrier, so that the target traffic data can be forwarded to the proxy server to realize network traffic acceleration requirements and the like.

In this step, a preset transmission path is carried into a target flow, and the target flow is transmitted to an external network, so that the target flow is transmitted through the external network according to the transmission path, and it is to be noted that the transmission path is different from a default transmission path of a common flow in the first flow, so that the intervention of the first device on the data flow of the second device is realized.

According to the processing method of the flow data, the first flow data sent by the second equipment is received through the network card equipment; identifying a target flow from the first flow data based on a preset flow processing rule; carrying a preset sending path into the target flow, and sending the target flow to an external network so as to send the target flow according to the sending path through the external network. In the method, after the first device is in communication connection with the second device according to the wireless network established by the network card device, the network card device receives the flow data sent by the second device, and identifies the target flow from the flow data and controls the sending path of the flow according to the preset flow processing rule, so that the intervention of the application program in the host device on the data flow of the client device is realized, and the function expansion of the client device and the application program is facilitated.

Before the first device intervenes in the traffic data of the second device, the operating system of the first device needs to complete preparation work of establishing the wireless network, communication connection with the second device, and the like.

The following embodiments take a USB network card device as an example, and introduce a specific implementation manner in which the first device establishes a wireless network through the USB network card device.

First, a USB network card device needs to be customized, and the network card device needs to have a unified hardware standard and be configured with a corresponding driver.

In this embodiment, the main control chip of the USB network card device uses the USB network card chip disclosed in the industry to support the establishment of a hotspot network in the 5Ghz band, and if the operating system of the first device is an iOS operating system, the network card also needs to include an MFi dedicated chip provided by apple. In addition, the network card device further has a USB type c male port and a USB type c female port (for the iOS platform, may be a Lightning male port), as shown in fig. 3, where the male port is used to connect to the first device, so that the first device may communicate with the USB network card device, and meanwhile, the first device may also supply power to the USB network card device. The female port is used for connecting an external data line and can supply power for the network card device and the first device simultaneously, and in the scene, the USB type c male port supplies power from the first device to the network card device, and the network card device is changed into the network card device to supply power for the first device. Further, a USB network card driver is obtained, where the network card driver is a special program that enables the intelligent device to communicate with the network card device, and the operating system of the first device can only control the operation of the USB network card device through the special program. When the first device is a mobile intelligent device such as a mobile phone or a notebook computer, only an application program of user mode authority is allowed to run on the mobile device, so that a linux kernel mode driver corresponding to hardware needs to be rewritten into the user mode driver to realize the control operation of the first device on the data flow of the second device. In the mode, the network card equipment is provided with a unified hardware standard and a driver program with authority matched, so that various problems of inconsistent standard, excessively complex software codes and the like caused by hardware fragmentation are avoided.

Further, the operating system of the first device implements hardware initialization and basic hardware communication functions using drivers. For example, according to the hardware initialization and basic hardware communication functions implemented by a USB API (Application Programming Interface, application program interface) provided by a first device operating system platform (such as iOS or Android system platform), it is detected whether a USB network card is connected to the first device and an underlying communication connection is established with the USB network card through the USB API.

Further, after the USB network card device is connected to the first device, the operating system of the first device establishes a wireless network using the USB network card driver. Specifically, detecting that the network card equipment and the first equipment establish communication connection, and acquiring network card information of the network card equipment; wherein, this network card information includes: one or more of hardware version, support function specification, and physical address; based on the network card information, configuring a firmware program for the network card equipment, and initializing a hardware register of the network card equipment; setting a network frequency band and a network encryption mode, broadcasting wireless signals, and obtaining a wireless network.

Specifically, the physical address, i.e., the MAC address, is an access control address of the traffic. Each network card device has a determined hardware version and corresponding support function specifications and physical addresses. When the USB network card device is detected to establish communication connection with the first device, one or more of hardware version, support function specification and MAC address in the network card information of the network card device are acquired,

Further, according to the acquired network card information, the first device operating system uses the user mode driver to configure a firmware program for the network card device, so that the operating system of the first device realizes operation according to the configured firmware program.

Further, the hardware registers of the network card device are initialized, and it can be understood that the related functions of the hardware of the USB network card are controlled by reading and writing the related register values, and different hardware registers are defined differently, so that the hardware registers of the network card device need to be initialized.

Finally, setting a proper frequency band, a network frequency band and a network encryption mode according to the requirement, starting SSID (Service Set Identifier, service set identification) signal broadcasting, and starting a hot spot to obtain a wireless network.

The following examples provide implementations in which a first device establishes a communication connection with a second device.

After the operating system of the first device uses the user mode driver to start the hotspot network, the wireless local area network protocol needs to be continuously realized, so that the client device is supported to connect with the hotspot, and data is transmitted. In this embodiment, the wireless lan protocol is an 802.11 protocol, and the implementation process includes the following steps:

1) The drive code uses USB protocol to read and write USB network card equipment, and the read and written data format is 802.11 packet packaged by hardware drive;

2) According to different USB network card hardware, encrypting and decrypting the drive head to obtain an 802.11 packet;

3) The following settings are made to the first device to cause the second device to discover the hotspot signal:

a. the USB network card device is driven to regularly broadcast a beacon packet, and then the client device can see wifi signals of the first device hotspot network in a wifi list;

b. when the second device actively transmits a probe detection packet (probe is an action or object used to detect the network state in telecommunication terminology), the probe is used to detect information about a wifi signal, for example: signal strength, device name, etc., and the first device driver replies to the detection request after receiving it.

It will be appreciated that when the second device requests to establish a communication connection with the first device, password authentication is required, and the first device confirms that authentication is successful and then establishes a communication connection with the second device. Specifically, receiving a connection verification request sent by a second device through a network card device; wherein the connection verification request comprises an encryption password of the wireless network; verifying the encryption password in the connection verification request, and if the encryption password is verified to be correct, sending a response data packet which is successfully verified to the second device; and receiving a connection request sent by the second equipment, determining that the second equipment meets a preset condition, sending a response message of successful connection to the second equipment, and establishing communication connection corresponding to a preset wireless local area network protocol with the second equipment.

Illustratively, the process includes;

1) When the second device prepares to connect to the wireless network, sending an auth authentication request, wherein auth is a basic user authentication, and the connection authentication request comprises an encryption password of the wireless network;

2) After the first device receives the verification request, the driving code checks whether the password is correct, if the encrypted password is verified to be correct, an auth success response packet is replied to the second device, and if not, connection is refused;

3) After the first equipment is successfully verified, the second equipment sends a connection request to join the wireless network;

4) And receiving a connection request sent by the second equipment, determining whether the second equipment meets a preset condition, replying an allowed passing message after meeting the condition, and establishing communication connection corresponding to an 802.11 protocol between the first equipment and the second equipment until the 802.11 connection is successful, wherein data packets are received and transmitted between the first equipment and the second equipment through the 802.11, so that high-speed transmission of data is realized.

Correspondingly, when the second device prepares to disconnect the wireless network, a disconnection request is sent to request for disconnecting the hot spot notification, and after the first device receives the notification, relevant resources applied for the device before the first device is emptied are recovered to confirm the disconnection request, and the relevant resources are released.

Fig. 4 shows a schematic diagram of multiparty interaction in the whole process of establishing communication between the first device and the second device in this embodiment, where the process is implemented by interaction between the first device and the second device, specifically including the following steps:

step S402, a first device driving code uses a USB protocol to read and write USB network card devices, and the read and written data format is an 802.11 packet packaged by a hardware driver;

step S404, the first equipment encrypts and decrypts the drive head according to different USB network card hardware to obtain an 802.11 packet;

step S406, the first device drives the USB network card device to periodically broadcast a beacon packet, so that the client device can see wifi signals of the first device hotspot network in a wifi list;

step S408, the second device actively transmits a probe detection packet for detecting related information of a wifi signal;

in step S410, the driver of the first device replies to the detection request after receiving the probe detection packet.

Step S412, when the second device prepares to connect to the wireless network, an auth verification 5 request is sent to the first device, wherein the connection verification request comprises an encryption password of the wireless network;

step S414, after the first device receives the verification request, the drive code checks whether the password is correct, if the encrypted password is verified to be correct, the second device is replied with an auth success response packet, otherwise, the connection is refused;

Step S416, after the first equipment is successfully verified, the second equipment sends a connection request to join the wireless network;

step S418, receiving the connection request sent by the second device, and determining whether the second device meets the pre-set

And setting a condition, and replying to allow the message to pass after the condition is met.

Up to this, 802.11 connection is successful, and the first equipment establishes the communication connection that 802.11 protocol corresponds with the second equipment, and data package is received and sent through 802.11 between first equipment and the second equipment, realizes the high-speed transmission of data.

And 5, in the interaction process of the first equipment and the second equipment, the first equipment drives the USB network card equipment by using a driving program of the USB network card equipment, so that a transmitting hot spot is realized, communication connection is established with the second equipment, and a foundation is laid for subsequently controlling the data flow of the second equipment.

After the first device and the second device establish a communication connection corresponding to a preset wireless local area network protocol, 0, for connectivity of communication between the two devices, the first device needs to allocate various network parameters to the connected second device, and specifically needs to perform the following settings:

1) Realizing a virtual gateway;

it will be appreciated that the second device needs to be connected to the network and a gateway device, for example, the driver of the first device may be configured as a network address (IP address) of the gateway, for example 5.192.168.0.1.

2) Realizing the network protocol of the local area network, and distributing network addresses for the second equipment:

specifically, a network card device receives a discovery message of a local area network protocol sent by a second device; determining the number of devices connected by the first device through a wireless network; if the number of the devices is less than the preset number threshold, a reply message of the normal message is sent to the second device; the reply message includes: a network address assigned to the second device and a gateway address of the first device; and receiving a use request of the network address sent by the second equipment, determining whether the use request is legal, and if the use request is legal, determining that the network address allocation is successful.

In this embodiment, the lan protocol is a DHCP lan protocol, and when the second device is successfully connected to the first device through the lan protocol, a discovery packet is sent, for example: the dhcp discover packet is intended to dynamically apply for an IP address. After the first device receives the discovery message through the USB network card virtual gateway, the number of devices connected by the first device through the wireless network is checked.

In one case, if the first device finds that the current connected devices are less than the preset number threshold, the first device directly sends a reply message, for example: the dhcp offer packet includes the network address to be allocated to the second device and the IP address of the gateway. The second device checks whether the second device is used after receiving the dhcp offer data packet, and after selecting the use, the second device needs to send a dhcp request message to the virtual gateway to request to use the IP address. The USB network card virtual gateway of the first device checks whether the data packet of the dhcp request is legal or not after receiving the data packet of the dhcp request, if the use request is legal, the device can reply to the dhcp ack message, and the second device can confirm that the IP address and other information allocated to the device can be allowed to be used only after receiving the reply message. So far, the IP address assignment is successful, and the second device obtains the network address.

In another case, if the first device finds that the number of the currently connected devices is greater than or equal to the preset number threshold, the discovery message of the local area network protocol sent by the second device is ignored.

3) Transmitting the MAC address of the virtual gateway to the second device;

specifically, receiving an address inquiry request sent by the second device; generating a reply message of the address inquiry request, and sending the reply message to the second device; wherein the reply message includes the physical address of the second device.

Here, the second device needs to forward the IP address transmission request through the virtual gateway of the first device, so it is also necessary to know the physical address of the virtual gateway IP address of the first device. When the first device sends an address query request, for example: when the first device receives the arp request through the USB network card device and inquires the arp address of the virtual gateway, the first device constructs an arp response message to reply and inform the MAC address of the virtual gateway. When the second device knows the MAC address of the gateway, normal communication can be constructed.

Fig. 5 shows a schematic diagram of multiparty interaction in a process of perfecting communication between a first device and a second device in this embodiment, where the process is implemented by interaction between the first device and the second device, specifically including the following steps:

Step S502, the driver of the first device is configured as the network address of the gateway;

step S504, after the second device is successfully connected with the first device through the local area network protocol, a discovery message is sent;

step S506, after the first device receives the discovery message through the USB network card virtual gateway, checking the number of devices connected by the first device through the wireless network; if the number of the devices is greater than or equal to a preset number threshold, not processing the discovery message.

Step S508, if the number of devices is less than the preset number threshold, a reply message of the normal message is sent to the second device, where the reply message includes: a network address assigned to the second device and a gateway address of the first device;

step S510, the second device checks whether to use after receiving the reply message, and if the second device selects to use, the second device sends a request for using the network address to the virtual gateway of the first device;

step S512, the first device receives the use request of the network address sent by the second device, determines whether the use request is legal, and if the use request is legal, determines that the network address allocation is successful;

step S514, the second equipment sends an address inquiry request;

step S516, after receiving the address inquiry request through the USB network card device, the first device generates a reply message of the address inquiry request, and sends the reply message to the second device to inform the MAC address of the virtual gateway;

And step S518, after the second equipment receives the MAC address of the gateway, constructing normal communication of the wireless local area network protocol.

In the interaction process of the first device and the second device, the first device realizes a three-layer virtual gateway by using a driving program of the USB network card device, realizes an ARP/DHCP basic protocol, distributes various network parameters for the connected second device, and ensures the most basic connectivity.

After the operating system of the first device establishes a wireless network through the network card driver and ensures basic communication connectivity with the second device, the operating system starts to intervene in the data flow of the second device. In one embodiment, as shown in fig. 6, a specific flow of a method for processing flow data provided in the embodiment of the present application is described by taking a USB network card device as an example.

Step S602, receiving first flow data sent by a second device through network card equipment;

the step is the same as step S202, and thus will not be described in detail.

Step S604, obtaining the common flow except the target flow from the first flow data; the common traffic is sent to an external network, so that the common traffic is sent through the external network according to a default path; wherein the default path is different from the transmit path;

The normal traffic is traffic which does not need special processing, the traffic does not pass through information marks such as a destination network address, the normal traffic is sent to an external network, and the traffic is sent to an original destination of the traffic according to a default path through a default network outlet (for example, wi-Fi/5G/4G network) of the first device, wherein the default path is different from a sending path of the target traffic.

Step S606, the flow processing rule comprises flow screening information; the traffic screening information comprises a destination network address or binding information of a domain name and a host; screening target flow matched with the flow screening information from the first flow data;

the traffic processing rule is a traffic processing rule which is received in advance through an external network and issued by a preset network server. The first device receives a flow processing rule issued by a preset network server through an external network. The traffic handling rules include traffic screening information including destination network addresses, or binding information of domain names and hosts. For example: the binding information of the specified destination IP address or domain name and the host machine can be issued based on a specified cloud network game server of the developer. And screening the target flow matched with the first flow data according to the flow screening information.

It should be noted that, the target traffic is traffic of the transport layer, that is, before the target traffic is identified, the first traffic data needs to be converted, specifically, the first traffic data is converted into a first data packet corresponding to a preset wireless lan protocol; converting the first data packet into a second data packet corresponding to a preset internet protocol; and converting the second data packet into a transport layer data packet, and determining the transport layer data packet as the converted target traffic.

In one embodiment, the wlan protocol is an 802.11 protocol, and the above traffic data conversion manner is shown in fig. 7, namely:

1) Reading an original data packet of the USB network card device acquired by the driver, and converting the original data packet into an 802.11 format packet;
