Detailed Description

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.

It should be noted that the relational terms such as first and second, and the like, referred to in the following embodiments of the present application, are only used for distinguishing one entity or operation from another entity or operation, and are not used for limiting an actual sequential relationship between the entities or operations.

Referring to fig. 1, the data transmission system provided in the present application includes an electronic device and a network access device. It should be noted that, in the embodiment of the present application, no particular limitation is imposed on the entity presentation form of the electronic device and the network access device, for example, the entity presentation form of the electronic device may be a smartphone shown in fig. 1, and the entity presentation form of the network access device may be a router shown in fig. 1.

The electronic device and the network access device perform data interaction through network connection between the electronic device and the network access device, and the network connection may be wired network connection (for example, the electronic device and the network access device are directly connected through a data line, so as to establish wired network connection between the electronic device and the network access device), may also be wireless network connection (including but not limited to wireless communication modes such as bluetooth, infrared, and wireless fidelity), and may also establish wired network connection and wireless network connection at the same time. Through the network connection between the two, the network access equipment provides network access service for the electronic equipment. For example, when a data packet is to be transmitted, if the data packet to be transmitted is a data packet of a preset application, the electronic device adds a priority transmission identifier to the data packet to be transmitted to obtain a target data packet, transmits the target data packet to the network access device, and then the network access device preferentially transmits the target data packet according to the priority transmission identifier and transmits the target data packet to the opposite-end device through the network, so as to ensure the data transmission quality of the specific application.

It should be noted that fig. 1 described above only shows an example of a system architecture for implementing the embodiment of the present application, and the embodiment of the present application is not limited to the system architecture shown in fig. 1 described above. Various embodiments of the present application are presented below, taking the system architecture shown in fig. 1 as an example.

Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method according to an embodiment of the present application. The data transmission method is applied to the electronic device in the data transmission system provided by the present application, and as shown in fig. 2, the flow of the data transmission method provided by the embodiment of the present application may be as follows:

at 110, a data packet to be transmitted is obtained.

The data transmission method provided by the present application will be described below from the perspective of an electronic device.

The network access device provides a network access service for the electronic device, so that the electronic device can access a network (such as the internet, an internal network of an organization, and the like) through the network access device, and thus perform data interaction with other devices through the network. For example, a game application executed by the electronic device enables the user to play normally online by performing data interaction with a game server at the other end of the network.

In the embodiment of the application, the electronic device obtains a data packet to be sent in real time, where the data packet to be sent may be generated by a local application of the electronic device, or may be forwarded to the electronic device by other electronic devices when the electronic device shares a network with other electronic devices.

For example, when the electronic device runs a game application, the game application generates a data packet that needs to be sent to the game server, and the electronic device takes the data packet as a data packet to be sent.

For another example, referring to fig. 3, the network access device provides a network access service for the electronic device, the electronic device shares a network with other electronic devices, at a certain time, a certain instant messaging application run by other electronic devices generates a data packet that needs to be sent to the instant messaging server, and correspondingly transmits the data packet to the electronic device, and at this time, the electronic device takes the data packet as a data packet to be sent.

Of course, as can be understood by those skilled in the art, how to acquire a data packet to be transmitted by an electronic device may also be other situations not listed in the embodiments of the present application.

In 120, when the data packet to be sent is a data packet of a preset application, a priority sending identifier is added to the data packet to be sent to obtain a target data packet, where the priority sending identifier includes a random value obtained by pre-negotiation between the electronic device and the network access device.

It should be noted that, in the embodiment of the present application, only the data transmission quality of the preset application is guaranteed.

The preset application can be configured by the default of the electronic equipment, and can also be configured correspondingly by the electronic equipment according to the input of a user. For example, the electronic device configures, by default, an application having a high requirement on data transmission quality, such as a game application and a live broadcast application, as a preset application that needs to guarantee the transmission quality.

Correspondingly, after the electronic device obtains the data packet to be sent, the electronic device further parses the data packet to be sent to determine the application to which the data packet to be sent belongs, or to determine which application the data packet to be sent is generated by. And then, the electronic equipment further identifies whether the application to which the data packet to be sent belongs is a preset application, and if so, determines that the transmission quality of the data packet to be sent needs to be guaranteed.

In order to guarantee the transmission quality of the preset application, a priority sending identifier is provided in the embodiment of the present application, and the priority sending identifier is configured to instruct the network access device to send the corresponding data packet preferentially. In addition, in order to ensure the stability of data transmission, the preferential transmission identifier is a random value obtained by pre-negotiation between the electronic device and the network access device. The negotiation on how to send the identifier preferentially between the electronic device and the network access device is not specifically limited here, and may be configured by a person of ordinary skill in the art according to actual needs.

For example, when the electronic device establishes a network connection with the network access device, a negotiation request is generated according to a message format agreed with the network access device and transmitted to the network access device; the network access equipment generates a random value through a configured random number generation algorithm according to a negotiation request from the electronic equipment, takes the random value as a priority sending identifier, and then generates a negotiation response carrying the priority sending identifier with a message format agreed in advance with the electronic equipment to transmit to the electronic equipment; and if the electronic equipment receives the priority sending identifier returned by the network access equipment, returning a confirmation response to the network access equipment. And the electronic equipment and the network access equipment finish the negotiation of the prior sending identifier.

As described above, referring to fig. 4, when it is recognized that the data packet to be sent is a data packet of the preset application, the electronic device adds the preferential sending identifier to the data packet to be sent, and records the data packet to be sent with the preferential sending identifier as the target data packet. In this embodiment, no specific limitation is imposed on how to add the preferential transmission identifier to the data packet to be sent, and a person skilled in the art may configure the preferential transmission identifier according to actual needs, for example, the preferential transmission identifier may be added to a header field of the data packet to be sent, and the preferential transmission identifier may also be added to a trailer field of the data packet to be sent.

In 130, the target data packet is transmitted to the network access device, so that the network access device preferentially transmits the target data packet according to the preferential transmission identifier.

In the embodiment of the application, after the target data packet is obtained by adding the priority sending identifier to the data packet to be sent, the electronic device transmits the target data packet to the network access device.

On the other hand, after receiving the target data packet from the electronic device, the network access device determines that the target data packet needs to be preferentially sent according to the preferential sending identifier carried in the target data packet, so that the target data packet is preferentially sent according to a pre-configured preferential sending strategy, and the target data packet is transmitted to the corresponding opposite terminal device through the network. The specific configuration of the preferential transmission strategy is not limited herein, and can be configured by those skilled in the art according to actual needs.

For example, the network access device is configured with a priority transmission queue and a normal transmission queue, and the network access device is configured to transmit the data packets in the normal transmission queue after all the data packets in the priority transmission queue are completely transmitted. Therefore, when the network access equipment preferentially sends the target data packet, the target data packet is inserted into the preferential sending queue, and if other data packets are in front of the target data packet in the preferential sending queue, the network access equipment sends the target data packet after completing sending the other data packets in sequence; and if no other data packet is in the priority sending queue before the target data packet, the network access equipment directly sends the target data packet.

According to the method, the electronic device obtains the data packet to be sent, and when the data packet to be sent is the data packet of the preset application, the priority sending identifier is added to the data packet to be sent to obtain the target data packet, wherein the priority sending identifier comprises a random value obtained by pre-negotiation between the electronic device and the network access device, and finally the target data packet is transmitted to the network access device, so that the network access device sends the target data packet preferentially according to the priority sending identifier. Therefore, the electronic equipment negotiates a random value with the network access equipment in advance to serve as a priority sending identifier, and the electronic equipment adds the priority sending identifier for a data packet of a preset application needing to guarantee data transmission quality, so that the network access equipment can preferentially send the data packet added with the priority sending identifier according to the indication of the priority sending identifier, and the purpose of guaranteeing the data transmission quality of the specific application is achieved.

Optionally, in an embodiment, transmitting the target data packet to the network access device includes:

and the target data packet is copied at least once to obtain at least two target data packets, and the at least two target data packets are transmitted to the network access equipment.

In order to ensure that the network access device can receive the target data packet transmitted by the electronic device, the electronic device performs redundant transmission on the target data packet in the embodiment of the application.

When the electronic device transmits the target data packet to the network access device, the electronic device copies the target data packet at least once, so as to obtain at least two target data packets, wherein the at least two target data packets include an original target data packet and at least one copied target data.

It should be noted that, in the embodiment of the present application, the number of times of copying the target data packet is not particularly limited, and may be configured by a person having ordinary skill in the art according to actual needs.

After the target data packets are copied and at least two target data packets are obtained, the electronic equipment transmits the obtained at least two target data packets to the network access equipment. Therefore, even in the case of packet loss, the network access device can receive the target data packet transmitted by the electronic device to the greatest extent.

It can be understood that, since the electronic device transmits at least two target data packets to the network access device, regardless of the situation that the network access device does not receive the target data packets transmitted by the electronic device, the network access device may receive one target data packet transmitted by the electronic device, and may also receive at least two target data packets transmitted by the electronic device. Accordingly, the network access device may preferentially send only one received target data packet, and may preferentially send all received target data packets, and the like, which is not specifically limited in the embodiment of the present application and may be configured by a person of ordinary skill in the art according to actual needs.

Optionally, in an embodiment, the electronic device and the network access device establish N-way network connection, where N is a positive integer greater than or equal to 2, copy the target data packet at least once to obtain at least two target data packets, and transmit the at least two target data packets to the network access device, where the method includes:

(1) copying the target data packets for N-1 times to obtain N target data packets;

(2) and distributing the N target data packets to the N network connections one by one for transmission to the network access equipment.

In the embodiment of the application, in order to ensure the data transmission quality between the electronic device and the network access device, N-way network connection is established between the electronic device and the network access device, where N is a positive integer greater than or equal to 2. Accordingly, the electronic device may transmit the target data packet to the network access device through the multi-path network connection established between the electronic device and the network access device.

The electronic equipment copies the target data packet for N-1 times to obtain N-1 copied target data packets, wherein the N copied target data packets comprise N original target data packets. Then, the electronic device allocates the N target data packets to the N network connections one by one for transmission to the network access device, that is, allocates each target data packet of the N target data packets to one network connection for transmission to the network access device.

For example, referring to fig. 5, two network connections are established between the electronic device and the network access device, which are a first network connection based on a 2.4G frequency point and a second network connection based on a 5G frequency point, respectively, and accordingly, when the electronic device copies the target data packet, the electronic device copies the target data packet 2-1 times to 1 time to obtain two target data packets including the original target data packet, and then allocates one of the target data packets to the first network connection for transmission to the network access device, and allocates the other target data packet to the second network connection for transmission to the network access device.

Optionally, in an embodiment, adding a priority sending identifier to a data packet to be sent to obtain a target data packet, where the priority sending identifier includes:

and writing a priority sending identifier in the service type field of the data packet to be sent, and setting the data packet to be sent with the written priority sending identifier as a target data packet.

The embodiment of the present application provides an optional implementation manner for adding a priority sending identifier to a data packet to be sent.

It should be noted that a data packet can be divided into 3 parts, respectively, a header, a body and a trailer, wherein the body is used to fill in the data that needs to be transmitted actually, and the header and trailer are used to fill in some data related to auxiliary transmission, for example, the header includes a source IP address field and a destination IP address field, wherein the destination IP address field is used to fill in a destination IP address, the destination IP address is used to characterize to which the data packet is to be sent, the source IP address field is used to fill in a source IP address, and the source IP address is used to where the data packet is sent.

In addition, in order to ensure the transmission quality of the data packet, the packet header further includes a service type field, the service type field has 8 bits, the service type field includes a priority sub-field with 3 bits (the value can be from 000 and 111 all values), a service type sub-field with 4 bits and a reserved bit with 1 bit having to be set to 0.

Where the definition of 8 priorities of 3 bits is as follows:

111-network control;

110-internetwork control;

101-key;

100-fast speed;

011-flash;

010-fast;

001-first;

000-normal.

Wherein the priorities "111" and "110" are generally reserved for use by network control data (e.g., routing data). Priority "101" is recommended for voice data use, priority "100" is recommended for video conferencing and video streaming use, priority "011" is recommended for voice control data use, priorities "010" and "001" are recommended for data traffic use, and priority "000" is a default flag value.

However, while there is a definition of the priority subfield as above, the technical field has already discarded the priority subfield, typically populating "000" in the priority subfield by default. Therefore, in the embodiment of the present application, the priority subfield in the service type field can be directly multiplexed for filling the priority transmission identifier.

Correspondingly, referring to fig. 6, when adding the preferential transmission identifier to the data packet to be transmitted, the electronic device may write the preferential transmission identifier into the priority subfield in the service type field of the data packet to be transmitted. With this as a constraint, the data length negotiated by the electronic device and the network access device for the random value as the preferential transmission identifier is at most 3 bits.

Optionally, in an embodiment, after transmitting the target data packet to the network access device, the method further includes:

and receiving a response data packet which is preferentially sent by the network access equipment and corresponds to the target data packet.

In this embodiment, the network access device preferentially forwards a response packet returned by the peer device of the target packet to the electronic device, in addition to preferentially sending out the target packet from the electronic device.

After receiving a target data packet from the electronic device, the network access device records five-tuple data of the target data packet, including a source IP address, a source port, a destination IP address, a destination port, and a transport layer protocol, in addition to preferentially sending the target data packet.

And then, if the received data packet is matched with the recorded quintuple data of the target data packet, taking the data packet as a response data packet of the target data packet, and preferentially sending the response data packet to the electronic equipment.

For example, the five-tuple data of the target packet is recorded as: "192.168.1.1, 10000, TCP, 121.14.88.76, 80" form a five-tuple, where 192.168.1.1 is the source IP address of the destination packet, 10000 is the source port of the destination packet, TCP is the transport layer protocol of the destination packet, 121.14.88.76 is the destination IP address of the destination packet (indicating the peer device of the destination packet), and 80 is the destination port of the destination packet. If the five-tuple data of a packet is "121.14.88.76, 80, TCP, 192.168.1.1, 10000", where 121.14.88.76 is the source IP address of the packet, 80 is the source port of the packet, TCP is the transport layer protocol of the packet, 192.168.1.1 is the destination IP address of the packet, and 10000 is the destination port of the packet. Obviously, the quintuple data of the data packet matches the quintuple data of the target data packet, and the network access device preferentially sends the data packet to the electronic device as a response data packet of the target data packet.

On the other hand, the electronic device receives a response packet corresponding to the target packet preferentially sent by the network access device.

Optionally, in an embodiment, the method further includes:

when the electronic equipment disconnects the network connection with the network access equipment and establishes the network connection again, a new random value is negotiated with the network access equipment to be used as a priority sending identifier.

In the embodiment of the application, in order to prevent possible network attacks, the electronic device and the network access device perform negotiation of preferentially sending the identifier each time network connection is established.

When the network connection with the network access device is disconnected and the network connection is established again, the electronic device negotiates a new random value with the network access device as a priority sending identifier, which may specifically refer to the related description in the above embodiments, and details are not described here again.

Referring to fig. 7, fig. 7 is another schematic flow chart of a data transmission method provided in the present application. The data transmission method is applied to the network access device in the data transmission system provided by the present application, as shown in fig. 7, the flow of the data transmission method may be as follows:

in 210, a target data packet transmitted by the electronic device is obtained.

The data transmission method provided by the present application will be described below from the perspective of a network access device.

Accordingly, the network access device will receive the target data packet transmitted by the electronic device.

In 220, when the target data packet carries a priority sending identifier, the target data packet is preferentially sent, where the priority sending identifier includes a random value obtained by pre-negotiation between the network access device and the electronic device.

As described above, the target data packet transmitted to the network access device by the electronic device is added with the priority sending identifier, at this time, the network access device recognizes that the target data packet carries the priority sending identifier, and correspondingly determines that the target data packet needs to be sent preferentially according to the indication of the priority sending identifier, so that the target data packet is sent preferentially according to the pre-configured priority sending policy, and the target data packet is transmitted to the corresponding opposite terminal device via the network. The specific configuration of the preferential transmission strategy is not limited herein, and can be configured by those skilled in the art according to actual needs.

Optionally, in an embodiment, the obtaining the target data packet transmitted by the electronic device includes:

receiving a plurality of identical target data packets from the electronic device;

preferentially sending the target data packet, comprising:

when a first target data packet from the electronic device is received, if a network transmission protocol required by the first target data packet is a first preset network transmission protocol, the first target data packet is preferentially sent, and other subsequently received target data packets are discarded.

It can be understood that, since the electronic device transmits at least two target data packets to the network access device, regardless of the situation that the network access device does not receive the target data packets transmitted by the electronic device, the network access device may receive one target data packet transmitted by the electronic device, and may also receive at least two target data packets transmitted by the electronic device.

The network access equipment identifies a transmission layer network transmission protocol required by a first target data packet when receiving the first target data packet from the electronic equipment, preferentially sends the first target data packet if the network transmission protocol required by the first target data packet is a first preset network transmission protocol, and discards other subsequently received target data packets. The first predetermined network transport protocol may be any network transport protocol without a packet deduplication function, and may be configured by a person of ordinary skill in the art according to actual needs.

Optionally, in an embodiment, the preferentially sending the target packet further includes:

when a first target data packet from the electronic device is received, if the network transmission protocol required by the first target data packet is a second preset network transmission protocol, the first target data packet is preferentially sent, and other subsequently received target data packets are preferentially sent.

In the embodiment of the application, if the network access device identifies that the network transmission protocol required by the received first target data packet is the second preset network transmission protocol, the first target data packet is preferentially sent, and other subsequently received target data packets are preferentially sent. The second predetermined network transmission protocol may be any network transmission protocol without a data packet deduplication function, and may be configured by a person of ordinary skill in the art according to actual needs.

Optionally, in an embodiment, the network access device establishes a multi-path network connection with the electronic device, and receives a plurality of identical target packets from the electronic device, including:

one of a plurality of identical destination packets is received over each network connection.

As above, the network access device will receive one of a plurality of identical destination data packets over each network connection between it and the electronic device.

Referring to fig. 8, fig. 8 is a schematic flow chart of a data transmission method provided in the present application, and as shown in fig. 8, the flow of the data transmission method may be as follows:

in 310, when the electronic device establishes a network connection with the network access device, a random value is obtained through negotiation and is used as a preferential sending identifier.

The electronic device may establish a network connection with the network access device for the first time, or may perform a negotiation with the network access device for preferentially sending the identifier when establishing a connection with the network access device again.

The negotiation on how to send the identifier preferentially between the electronic device and the network access device is not specifically limited here, and may be configured by a person of ordinary skill in the art according to actual needs.

At 320, the electronic device obtains a data packet to be transmitted.

In 330, when the data packet to be sent is a data packet of a preset application, the electronic device adds a priority sending identifier to the data packet to be sent to obtain a target data packet.

In 340, the electronic device transmits the target data packet to the network access device.

In 350, the network access device preferentially transmits the target data packet according to the preferential transmission identifier.

After receiving the target data packet from the electronic device, the network access device determines that the target data packet needs to be preferentially sent according to a preferential sending identifier carried in the target data packet, so that the target data packet is preferentially sent according to a pre-configured preferential sending strategy, and the target data packet is transmitted to the corresponding opposite terminal device through the network. The specific configuration of the preferential transmission strategy is not limited herein, and can be configured by those skilled in the art according to actual needs.

At 360, upon receiving the response packet corresponding to the destination packet, the network access device preferentially sends the response packet to the electronic device.
