The present invention further provides a supplementary description of the service data transmission method provided in the foregoing embodiment.

In the following embodiments, a structure in which a transmitting-end device and a multi-card aggregation device are separated is specifically described.

As shown in fig. 2, a flowchart illustrating steps of another embodiment of a service data transmission method according to the present invention is shown, where the service data transmission method includes:

s201, the multi-card aggregation equipment sends test data packets to the server side equipment through a 5G network card and a 4G network card respectively, wherein the test data packets comprise network card identifiers, timestamps, the number of the sub-test packets and the serial numbers of the sub-test packets;

specifically, the embodiment of the present invention is applied to a transmission system of service data, where the transmission system of service data includes a sending end device, a multi-card aggregation device, and a server end device, the server end device is connected to a switch, and the switch allocates a service data packet, where the sending end device is connected to the multi-card aggregation device through a network cable, and the sending end device includes a device equipped with a camera, such as a camera or a computer equipped with a camera; the multi-card aggregation equipment comprises a plurality of card slots, and can be provided with a 4G network card and a 5G network card; the server side equipment is a dual-mode machine and can communicate with the video network and the Internet.

The number of the card slots in the multi-card aggregation device is not specifically limited in the embodiment of the present invention, and a suitable 5G network card and a suitable 4G network card may be installed as needed, where the 4G network card may preferably include network cards of various operators, such as a mobile network card, a universal network card, and a telecommunication network card, and if the network card signal of one of the operators is not good, the transmission efficiency of other network cards is not affected; the number of the 5G network cards can be set according to needs, and operators of the 5G network cards are not particularly limited.

Specifically, as an optional manner, in a service idle state, the multi-card aggregation device may send a test data packet to the server device through each network card in advance, so that the server device determines the transmission bandwidth and the packet loss rate according to a timestamp and a sequence number of the received test data packet, and determines the transmission bandwidth corresponding to the packet loss rate as a stable transmission bandwidth when the packet loss rate is smaller than a first preset value, so as to prepare for subsequent transmission of service data.

As another optional mode, the stable transmission bandwidth may be acquired before performing service transmission in real time, and specifically, before performing service transmission on a service data packet, the multi-card aggregation device sends a test data packet to the server device through each network card, where the test data packet includes each network card identifier and a timestamp, each test data packet further includes a plurality of sub-test packets, and the number of the sub-test packets and the sequence number of the sub-test packet are loaded in the test data packet and sent to the server device.

S202, the server side equipment determines the transmission bandwidth and the packet loss rate according to the timestamp and the sequence number of the received test data packet, and determines the transmission bandwidth corresponding to the packet loss rate as the stable transmission bandwidth under the condition that the packet loss rate is smaller than a first preset value.

Specifically, step S202 includes:

step A1, the server device determines the transmission bandwidth for transmitting the test data packet according to the size and the consumed time of the test data packet, wherein the consumed time is determined according to the sending time stamp and the receiving time stamp;

specifically, the server device obtains a sending timestamp for sending the test data packet and a receiving timestamp for receiving the test data packet by the multi-card aggregation device, and calculates time consumed for receiving the test data packet, that is, a time interval obtained by subtracting the receiving timestamp from the sending timestamp. The server device divides the consumed time, i.e. the time interval, by the size of the test data packet to obtain the test data packet received in unit time, i.e. the transmission bandwidth for transmitting the test data packet;

step A2, the server device determines the number of lost sub-test packets according to the serial numbers of the sub-test packets;

illustratively, the server device receives the sub-test packets with sequence numbers "1, 2, 3, 5, 7, 8, 9, 10", and discards the sub-test packets with sequence numbers "4, 6", that is, counts the number of the discarded sub-test packets as 2.

Step A3, the server device calculates the packet loss rate according to the number of the lost sub-test packets and the number of the sub-test packets.

Specifically, the server device receives the total number of the sub-test packets included in the test data packet, and calculates the packet loss rate according to the number of the lost sub-test packets and the total number of the sub-test packets.

Step A4, determining a transmission bandwidth corresponding to the packet loss rate as a stable transmission bandwidth under the condition that the packet loss rate is smaller than a first preset value;

specifically, the server device determines the calculated packet loss rate, and if the packet loss rate is greater than a certain value, the transmission speed of the network card needs to be reduced, that is, the number of bytes of the data packet sent each time is reduced until the packet loss rate is less than a first preset value, and in this case, the network transmission bandwidth at this time is determined as the stable transmission bandwidth.

Illustratively, if the packet loss rate is found to be greater than 20%, the transmission speed of the card is reduced until the packet loss rate is less than 10%, and the network transmission bandwidth at this time is recorded as the stable transmission bandwidth of the card.

S203, acquiring a data uploading bandwidth required by receiving the service data packet;

since step S203 is the same as step S101 in the embodiment shown in fig. 1. Step S101 has already been described in detail in fig. 1, and therefore step S203 is not described again here.

specifically, the embodiment of the present invention may include multiple 5G network cards and multiple 4G network cards, and because the data transmission capability of the 5G network card is strong, only one target 5G network card is usually selected.

The multi-card aggregation device judges the stable transmission bandwidth and the data uploading bandwidth of the 5G network card, if the stable transmission bandwidth of the 5G network card is smaller than the data uploading bandwidth, it indicates that only one 5G network card cannot meet the data transmission requirement, a plurality of target 4G network cards need to be selected from the 4G network cards, the absolute value of the difference between the stable transmission bandwidth and the data uploading bandwidth of the 5G network card is calculated, namely the first bandwidth difference, the first bandwidth difference and the m 4G network cards are judged, and a plurality of 4G network cards are determined according to the first bandwidth difference and the stable transmission bandwidths of the m 4G network cards, for example, one 4G network card can be determined, or the 4G network cards can also be a plurality of 4G network cards, wherein the plurality of 4G network cards specifically refer to two or more than two 4G network cards.

S205, determining one or more target 4G network card identifiers required to be adopted for transmitting the service data packet according to the comparison result, so that the 5G network card identified by the target 5G network card and the 4G network card identified by the target 4G network card meet the bandwidth requirement for transmitting the service data packet.

Specifically, the multi-card aggregation device judges a first bandwidth difference value and a stable transmission bandwidth of the 4G network card, and if the maximum stable transmission bandwidth of one 4G network card is greater than or equal to the first bandwidth difference value, determines the 4G network card as a target 4G card, and in this case, only one target 5G network card and one target 4G network card are needed to meet the bandwidth requirement for transmitting the service data packet;

if the maximum stable transmission bandwidth of one 4G network card is smaller than the first bandwidth difference, one 5G network card and one 4G network card cannot meet the bandwidth requirement for transmitting the service data packet, and then a plurality of target 4G network cards need to be selected from the remaining 4G network cards, so that the one target 5G network card and the plurality of target 4G network cards can meet the bandwidth requirement for transmitting the service data packet.

And S206, sending the service data packet to the server side equipment through the 5G network card corresponding to the target 5G network card identifier and the 4G network card corresponding to the target 4G network card identifier.

Specifically, after determining a 5G network card and a plurality of 4G network cards, the multi-card aggregation device splits the service data packet, and sends the split data packet to the server device through the 5G network card and the plurality of 4G network cards, which specifically includes:

step A1, determining the splitting ratio of the data packet according to the ratio of the stable transmission bandwidth corresponding to the target 5G network card identifier to the stable transmission bandwidth of the target 4G network card identifier;

a2, splitting the service data packet according to the splitting ratio of the data packet to obtain a first sub-service data packet corresponding to the target 5G network card identifier and a second sub-service data packet corresponding to the target 4G network card identifier;

step A3, sending the first sub-service data packet to a server device through a 5G network card corresponding to the target 5G network card identifier;

specifically, the multi-card aggregation device packages the first sub-service data packet according to an internet access data protocol, and sends the first sub-service data packet to the server device through the 5G network card corresponding to the target 5G network card identifier, wherein the internet access data protocol is obtained by analyzing the service data packet, and the type of the internet access data protocol at least comprises one of HTTP, TCP or UDP;

and step A4, sending the second sub-service data packet to the server device through the 4G network card corresponding to the target 4G network card identifier.

Specifically, the multi-card aggregation device packages the second sub-service data packet according to an internet access data protocol, and sends the second sub-service data packet to the server device through the 4G network card corresponding to the target 4G network card identifier, where the internet access data protocol is obtained by analyzing the service data packet, and the type of the internet access data protocol at least includes one of HTTP, TCP, or UDP.
