[0045] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0046] At present, with the increasing maturity of computer networks, convenient and fast information communication and collaboration methods have become a hot spot in network technology research and development. As a new communication and exchange tool, video conferencing has broken through geographical restrictions, and in-vehicle video conferencing applied to vehicles has developed rapidly. In-vehicle video conferencing usually uses multi-channel network card management, and there is a binding driver for multi-channel network card management. When the network card forwards the code stream data, it informs the binding driver through polling, and the binding driver may randomly assign the code stream data to different network cards for processing. Although load balancing is achieved, there are two defects: first, polling takes extra time; second, each forwarding of code stream data will occupy all network cards, resulting in resource waste.

[0047] Based on this, the present invention provides a method for managing a network card. Figure 1 A flowchart of a method for managing a network card provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes:

[0048] Step S101: receiving real-time stream forwarding capability information of each network card, a stream forwarding request of a client device, and stream data.

[0049] In actual applications, the client device registers to the audio and video server by configuring an account, and encodes the audio and video data collected by the camera and microphone inside the vehicle and sends it to the audio and video server.

[0050] The network card management pool in the audio and video server receives the code stream data and code stream forwarding request from the client device, and also receives the real-time code stream forwarding capability information of each network card. The network card management pool controls the corresponding network card to forward the code stream data according to different real-time code stream forwarding capability information.

[0051] Step S102: Based on the received stream forwarding request and the real-time stream forwarding capability information of each network card, a network card corresponding to the maximum stream forwarding capability information at the current moment is selected as the target network card.

[0052] In actual applications, after receiving the stream forwarding request from the client device, the network card management pool preferentially selects the network card with the largest stream forwarding capability information at the current moment as the target network card based on the real-time stream forwarding capability information of each network card, that is, selects the network card with the smallest used stream forwarding capability information as the target network card.

[0053] Step S103: Control the target network card to forward the code stream data to the corresponding client device.

[0054] In actual applications, when an in-vehicle video conference is established, there will be multiple client devices. The network card management pool controls the target network card to forward the stream data of the current client device to other client devices. It will also send the video data of other client devices to the vehicle's central control display screen and send the audio data to the speaker to establish an in-vehicle video conference.

[0055] Through the above embodiment, the real-time code stream forwarding capability information of each network card, the code stream forwarding request of the client device, and the code stream data are received; based on the received code stream forwarding request and the real-time code stream forwarding capability information of each network card, the network card corresponding to the maximum value of the code stream forwarding capability information at the current moment is selected as the target network card; the target network card is controlled to forward the code stream data to the corresponding client device. This process saves the time of code stream forwarding and the use resources of the network card by selecting the network card corresponding to the maximum value of the code stream forwarding capability information as the target network card and forwarding the code stream data to the corresponding client device, while improving the throughput of the network card.

[0056] In one embodiment, the method further comprises:

[0057] Randomly generate the timeout duration for each network card;

[0058] When each network card does not receive heartbeat information within the corresponding timeout period, the network card with the smallest timeout period is selected as the candidate network card;

[0059] Increase the term number value of the candidate network card and control the candidate network card to vote for the candidate network card;

[0060] Each network card except the candidate network card is used as a follower network card, and the candidate network card is controlled to send a voting request message to each follower network card;

[0061] When each follower network card receives the voting request information and determines that the follower network card has not sent voting information within the current term number, each follower network card is controlled to send voting information to the candidate network card;

[0062] Increase the term number value of each follower network card;

[0063] After the candidate network card receives the voting information of each follower network card, the candidate network card is determined to be the leader network card.

[0064] In actual applications, when a network card is accidentally damaged during a video conference, the video conference will be affected, and each network card needs to be tested to ensure the stability of the video conference. Specifically, the network card is set to different roles such as follower network card, candidate network card and leader network card.

[0065] In actual applications, the timeout period for each network card to receive heartbeat information is randomly generated. For example, the timeout period of network card A is randomly set to 150 milliseconds, the timeout period of network card B is randomly set to 200 milliseconds, the timeout period of network card C is randomly set to 250 milliseconds, and the timeout period of network card D is randomly set to 300 milliseconds. In the initial state, when each network card does not receive the heartbeat information sent by the leading network card within the corresponding timeout period, the network card with the shortest timeout period among multiple network cards is selected as the candidate network card. Taking the above example, network card A can be selected as the candidate network card.

[0066] In actual applications, the candidate network card needs to send a request for voting information to other network cards to notify other network cards to vote for the candidate network card. After the candidate network card obtains the votes of each network card, it is promoted to the leading network card. Specifically, the network cards other than the candidate network card are determined as follower network cards. The candidate network card will increase its term number value and vote for itself. At the same time, a request for voting information is sent to each follower network card, requesting each follower network card to vote for the candidate network card. Taking network card A as a candidate network card as an example, the initial term number value of network card A is 0. When network card A is determined to be a candidate network card, the term number value becomes 1, and a request for voting information is sent to follower network card B, follower network card C, and follower network card D.

[0067] In actual applications, after receiving the request voting information, each follower network card determines whether to send voting information to other network cards within the current term number. When it is determined that each follower network card has not sent voting information to other network cards, it sends voting information to the candidate network card and increases the term number value corresponding to each follower network card. Specifically, taking the above as an example, after follower network card B, follower network card C, and follower network card D receive the request voting information from candidate network card A and determine that they have not sent voting information to other network cards within the current term number, they send voting information to candidate network card A and change the corresponding term number value from the initial value 0 to 1.

[0068] In actual application, after the candidate network card receives the voting information of each follower network card, the candidate network card is determined to be the leader network card. Specifically, taking the above example, after the candidate network card A receives the voting information of follower network card B, follower network card C and follower network card D, the candidate network card A is promoted to the leader network card.

[0069] In actual applications, the main work of the follower NIC is to receive and process messages from the leader NIC. When the waiting time for the leader NIC heartbeat information times out, it will take the initiative to stand up and recommend itself as a candidate NIC. The main work of the candidate NIC is to send a request for voting information to other NICs, notifying other follower NICs to vote for itself. If it wins the majority of votes, it will be promoted to the leader NIC. The main work of the leader NIC is to send heartbeat information to ensure that the leader NIC is working properly, without the need to elect other NICs as the leader NIC.

[0070] Through the above embodiment, the process sets multiple network cards to different roles, and can automatically switch the roles of network cards after the network card is damaged, thereby avoiding the problem of poor viewing effect of in-vehicle video conferencing caused by damage to a certain network card, and ensuring the security and stability of in-vehicle video conferencing.

[0071] In one embodiment, after the candidate network card receives the voting information of each follower network card and determines that the candidate network card is the leader network card, the following steps are performed:

[0072] Control the leading network card to send heartbeat information to each follower network card at a first preset period;

[0073] When the leader network card receives the heartbeat feedback information of the follower network card, it determines that the follower network card is operating normally.

[0074] In actual applications, after determining the leading network card, the leading network card sends heartbeat information to other following network cards at a first preset period to determine that the leading network card works normally, and there is no need to elect other network cards as the leading network card. The first preset period can be set as needed.

[0075] In actual applications, after receiving the heartbeat information, the follower network card will send a heartbeat feedback message to the leader network card, indicating that the heartbeat information of the leader network card has been received. After receiving the heartbeat feedback message, the leader network card determines that the corresponding follower network card is running normally and can forward the code stream data.

[0076] Through the above embodiment, the leading network card sends heartbeat information to each follower network card at a first preset period, notifying the heartbeat information that the leading network card is operating normally, and there is no need to select other network cards as the leading network card. At the same time, the leading network card determines that the follower network card is operating normally based on the heartbeat feedback information received from the follower network card. This process can effectively detect the operating status of the leading network card and the follower network card, ensure that each network card forwards the code stream data normally, and thus ensure the security and stability of the in-vehicle video conference.

[0077] In one embodiment, the method further comprises:

[0078] When the leading network card does not receive the heartbeat feedback information of the following network card, it is determined that the following network card operates abnormally.

[0079] In actual applications, when the leading network card does not receive the heartbeat feedback information of the following network card, it is determined that the following network card is operating abnormally and the following network card is in a fault state. After receiving the stream forwarding request of the client device, the following network card in the faulty state is eliminated and the following network card operating normally is selected to forward the stream data.

[0080] Through the above embodiment, after the leading network card does not receive the heartbeat feedback information of the following network card, it determines that the following network card is operating abnormally and is in a faulty state. When forwarding stream data, the network card management pool will exclude the network card in the faulty state and select the network card that is operating normally for data forwarding, thereby ensuring the security and stability of the in-vehicle video conference.

[0081] In one embodiment, the method further comprises:

[0082] Sending a detection data packet to each network card every second preset period;

[0083] Control each network card to generate reassembled data packets based on the detected data packets;

[0084] Calculate the packet loss rate of each network card based on the detection data packets and reassembled data packets;

[0085] When the packet loss rate of the target network card is greater than a preset value, the network card with a packet loss rate less than or equal to the preset value is used to forward the code stream data to the corresponding client device.

[0086] In actual applications, when the network of a certain network card is not very stable or network congestion occurs, if the code stream is still transmitted to the network card, the network card will lose a large amount of code stream data from the client device due to network problems, resulting in image freezes and sound loss in the in-vehicle video conference. Based on this, the present application sends a detection data packet to each network card every second preset period. After receiving the detection data packet, each network card reassembles the detection data packet to obtain a reassembled data packet, and sends the reassembled data packet to the network card management pool. The network card management pool calculates the packet loss rate of each network card based on the detection data packet and the reassembled data packet. Within a certain period, when it is detected that the packet loss rate of the target network card is greater than the preset value, the network card with a packet loss rate less than or equal to the preset value is automatically switched to forward the code stream data to the corresponding client device. Among them, the preset value can be set to 10%, and this application does not limit it. When the network returns to normal, switch the network card to the target network card so that the target network card continues to forward the code stream data to the corresponding client device.

[0087] Through the above embodiment, a detection data packet is sent to each network card at a second preset period, and the packet loss rate of each network card is calculated according to the detection data packet and the reassembled data packet processed by each network card. When the packet loss rate of the target network card exceeds the preset value, a network card less than or equal to the preset value is selected to forward the code stream data, thereby ensuring the stability of the in-vehicle video conference and improving the viewing experience of the client device for the in-vehicle video conference.

[0088] In one embodiment, the method further comprises:

[0089] Generate a secret key based on the first received bitstream data and obtain a secret key generation rule;

[0090] Based on the key generation rule, generate a key for the code stream data other than the code stream data received for the first time;

[0091] Control the target network card to forward the stream data to the corresponding client, including:

[0092] Control the target network card to forward the code stream data and the corresponding key to the corresponding client device.

[0093] In actual applications, after receiving a stream forwarding request from a client device, a secret key is randomly generated based on the first received stream data and sent to other client devices, and a secret key generation rule is obtained based on the secret key. When other stream data is received, a corresponding secret key is generated based on the secret key generation rule and the corresponding stream data.

[0094] In actual applications, the target network card is controlled to forward the code stream data and the secret key corresponding to the code stream data to the corresponding client device. The client device decrypts the code stream data according to the secret key and the key generation process to obtain the audio and video data.

[0095] Through the above embodiment, a key generation rule is generated by using the code stream data received for the first time, a key corresponding to the code stream data is generated using the key generation rule, and the key is sent to the corresponding client device, thereby ensuring the security of the in-vehicle video conference.

[0099] The data forwarding module 203 is used to control the target network card to forward the code stream data to the corresponding client device.
