Detailed ways

The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

In a traditional video conferencing system, at least two lines are supported to establish a conference connection between a terminal and a video conferencing platform.

Taking at least two lines including the main E1 line and the standby E1 line as an example, Fig. 1 is a schematic structural diagram of a traditional video conferencing system provided by the present application. According to Fig. 1, it can be seen that the video conferencing system includes a video conferencing platform 10 and a terminal 20.

Among them, the video conferencing platform 10 includes a master E1 board 101 and a backup E1 board 102 at the physical layer, a platform hardware driver 103 at the link layer, and a platform service 104 at the application layer. The terminal 20 includes a primary E1 interface 201 and a backup E1 interface 202 at the physical layer, a terminal hardware driver 203 at the link layer, and an upper-layer application 108 at the application layer. The main E1 interface 201 is connected to the main E1 board 101 through an E1 connection line to form a main line, and the standby E1 interface 202 is connected to the standby E1 board 102 through an E1 connection line to form a backup line.

After the terminal is started, the terminal hardware driver 203 and the platform hardware driver 103 determine whether a physical failure occurs in the main line and the backup line based on the service detection mechanism.

Generally, the line priority of the main line is higher than that of the standby line. At this time, the terminal preferentially uses the main line to establish a conference connection with the video conference platform. The specific process includes:

Step 1, the upper layer application of the terminal sends a registration request through the main line, and the registration request carries the terminal IP address of the terminal;

Step 2: After receiving the registration request, the main E1 board registers the terminal IP address locally, converts the terminal IP address into the IP address of the E1 board itself, and then sends the registration command to the platform business, and the platform business replies that the registration is successful Afterwards, the main E1 board will reply the registration success response to the terminal.

Step 3, the platform service initiates a call to the main E1 board according to the IP address carried in the call instruction;

Step 4: After the main E1 board receives the call, if the main E1 line is normal, initiate a call to the terminal based on the pre-registered terminal IP address through the main E1 line; if the main E1 line is abnormal, then perform steps 1- 4.

Step 5: After receiving the call, the terminal establishes a conference connection with the platform service in response to receiving the confirmation operation.

After the conference connection is established, the upper-layer application and the platform service determine whether the main line fails based on the signaling keep-alive mechanism.

Afterwards, if it is determined that the main line fails and a physical failure occurs on the main line, the terminal performs the above steps 1-5 again based on the backup line to establish a conference connection through the backup line to achieve disaster recovery.

Taking at least two lines including an E1 line and an IP line as an example, FIG. 2 is a schematic structural diagram of another traditional video conferencing system provided by the present application. According to FIG. 2 , the video conferencing system includes a video conferencing platform 10 and a terminal 20 .

Among them, the video conferencing platform 10 includes an E1 board 105 and an IP board 106 at the physical layer, a platform hardware driver 107 at the link layer, and a platform service 108 at the application layer. The terminal 20 includes an E1 interface 205 at the physical layer, an Ethernet interface 206, a terminal hardware driver 207 at the link layer, and an upper-layer application 208 at the application layer. The E1 interface 205 is connected to the E1 board 105 through an E1 connection line to form an E1 line, and the Ethernet interface 206 establishes an IP network with the IP board 106 through an IP protocol to form an IP line.

After the terminal is started, the terminal hardware driver 207 and the platform hardware driver 107 determine whether a physical failure occurs on the E1 line based on a service detection mechanism.

Generally, the line priority of E1 lines is higher than that of IP lines. At this time, the terminal preferentially uses the E1 line to establish a conference connection with the video conference platform. For the specific process, refer to the above steps 1-5:

Afterwards, if it is determined that the E1 line is faulty and the E1 line is physically faulty, the terminal performs the above steps 1-4 again based on the IP line to establish a conference connection through the IP line to achieve disaster recovery.

According to the above two examples, in the traditional video conferencing system, whether there are at least two E1 lines or E1 lines + IP lines, the platform service needs to replace the IP address of the board corresponding to another line to make a call during disaster recovery. , the calling method changes, which will increase the complexity of platform business calls.

In addition, in this application, an E1 board refers to a board that supports data transmission using the E1 standard, and an IP board refers to a board that supports the establishment of an IP network using the IP protocol.

Based on the above technical problems, this application provides a video conferencing system, which supports the establishment of E1 lines and IP lines, and the EI board corresponding to the EI line is connected to the IP board corresponding to the IP line, no matter which line is used to establish a conference Connection, the IP board always communicates with the service platform, which enables the service platform to always use the IP address of the IP board to make calls without changing the calling method, which can reduce the complexity of platform service calls.

Specifically, FIG. 3 is a schematic structural diagram of a video conference system provided by an embodiment of the present application. According to FIG. 3 , the video conference system includes a video conference platform 30 and a terminal 40 .

The video conferencing platform 30 includes: an E1 board 301 located in the frame and a main IP board 302; the main IP board 302 has an external IP address, and the E1 board 301 is configured with the external IP address.

Optionally, the E1 board 301 and the main IP board 302 may be located in the same chassis, or may also be located in different chassis. In the case that the E1 board 301 and the main IP board 302 are located in different chassis, the E1 board 301 and the main IP board 302 may be connected based on a switch.

The terminal 40 includes an Ethernet interface 402 and an E1 interface 401. The Ethernet interface is suitable for establishing an IP line with the external IP address based on the IP protocol. The E1 interface is suitable for being connected to an E1 board through an E1 connection line to form an E1 line.

In this embodiment, the terminal is used to obtain a preset line priority; and perform data transmission with the video conference platform based on the normal line with the highest line priority.

Generally, the order of line priority from high to low is: E1 line is higher than IP line. In other embodiments, the line priority may also be in other manners, and this embodiment does not limit the setting manner of the line priority.

Wherein, the data includes signaling and code stream, for example: the signaling that needs to be transmitted during the establishment of the conference connection and the code stream transmitted after the conference connection is established.

Correspondingly, the video conferencing platform is used to transmit the data sent by the terminal to the main IP board through the E1 board for processing when the normal line is an E1 line established based on the E1 board; The data is transmitted to the E1 board through the main IP board to be sent to the terminal through the E1 line; when the normal line is an IP line established based on the external IP address, the data sent by the terminal is obtained through the main IP board for processing. And the data to be sent to the terminal is sent to the terminal through the IP line.

According to the above data transmission process, it can be seen that no matter whether the E1 line is used to transmit data or the IP line is used to transmit data, the service platform always communicates with the IP board, that is, the service platform does not perceive which line is currently used, which makes the service platform The IP address of the main IP board can always be used to make calls, and the calling method does not need to be changed, which can reduce the complexity of platform service calls.

With reference to Fig. 4, in order to improve the reliability of the video conferencing system, the frame includes a first frame and a second frame, and the first frame and the second frame are connected through a switch, so that the first frame and the second frame Data exchange between them; both the first frame and the second frame include E1 boards and IP boards, and the IP boards in the first frame and the second frame preempt the video conferencing platform reservation based on the preset master selection algorithm. The external IP address is set, and the IP board with the external IP address is the master IP board.

Optionally, the preset master selection algorithm may be zookeeper, or kafka, etc. This embodiment does not limit the implementation of the preset master selection algorithm.

Correspondingly, the E1 interface includes the main E1 interface and the standby E1 interface, wherein the E1 line formed by the E1 board connected to the main E1 interface is the main E1 line; the E1 line formed by the E1 board connected to the standby E1 interface is the standby E1 line.

In the system framework shown in Fig. 4, comprise three lines of lines, each line is according to line priority from high to low: primary E1 line, backup E1 line, IP line, in other embodiments, line priority is also It can be implemented in other manners, and this embodiment does not limit the implementation manner of line priority.

Optionally, the data transmission based on the normal line with the highest line priority and the video conferencing platform includes at least the following two scenarios. The first scenario is a conference connection establishment scene, and the second scenario is a conference connection use after the conference connection is established. Scenarios, the data transmission process of each scenario is introduced below.

The first scenario: a conference connection establishment scenario. If the normal line with the highest line priority is the main E1 line, the process for the terminal to establish a conference connection with the video conferencing platform using the E1 line includes:

Step 11, the upper layer application of the terminal sends a registration request through the main E1 line, and the registration request carries the terminal IP address of the terminal;

Step 12: After receiving the registration request, the main E1 board registers the terminal IP address locally, and converts the terminal IP address in the registration request into the IP address of the E1 board itself, and then registers the registered IP address carrying the converted IP address. The command is sent to the main IP board of the platform;

Wherein, the main E1 board stores the corresponding relationship between the terminal identification of the registered terminal and the terminal IP address.

Step 13, the main IP board registers the IP address of the main E1 board carried in the registration command locally, and after the main IP board replies that the registration is successful, the main E1 board replies the registration success response to the terminal;

Step 14, the platform service initiates a call to the main IP board based on the call instruction;

Step 15, after the main IP board receives the call, initiate a call to the main E1 board based on the IP address of the pre-registered main E1 board;

Step 16, after the main E1 board receives the call, if the main E1 line is normal, initiate a call through the main E1 line, if the main E1 line is abnormal, perform steps 11-15 again through the standby E1 line (the difference is that the main E1 standby E1 board), if the standby E1 line is abnormal, perform steps 21-25 for the line;

Step 17: After receiving the call, the upper application of the terminal establishes a conference connection with the video conference terminal if it confirms the call, and the process ends.

If the normal line with the highest line priority is an IP line, the process of establishing a conference connection between the terminal and the video conferencing platform includes:

Step 21, the upper layer application of the terminal sends a registration request through the IP line, and the registration request carries the terminal IP address of the terminal;

Step 22, the main IP board registers the terminal IP address carried in the registration request locally;

Step 23, the platform service initiates a call to the main IP board based on the call instruction;

Step 24, after receiving the call, the main IP board initiates a call to the terminal based on the pre-registered terminal IP address;

Step 25: After receiving the call, the terminal upper application establishes a conference connection with the video conference terminal if it confirms the call.

According to steps 11-17 or steps 21-25, it can be seen that the platform service only needs to call the main IP board, and there is no need to change the calling mode. Therefore, the calling mode of the platform service can be simplified.

The second scenario: the usage scenario of conference connection. If the normal line with the highest line priority is an E1 line, the process for the terminal to use the E1 line and the video conferencing platform to use the conference connection to transmit the code stream includes:

Step 31, the upper layer application of the terminal sends the code stream through the E1 line;

Step 32, the E1 board sends the code stream to the main IP board after receiving the code stream;

Step 33, the main IP board sends the code stream to the data processing board;

Among them, the relevant description of the data processing board is as follows;

Step 34, the platform service sends the code stream to be sent to the terminal to the main IP board through the data processing board;

Step 35, after receiving the code stream to be sent to the terminal, the main IP board sends the code stream to be sent to the terminal to the E1 board;

Step 36, after receiving the code stream to be sent to the terminal, the E1 board sends the code stream to be sent to the terminal to the terminal;

In step 37, the upper layer application of the terminal plays the code stream after receiving it.

If the normal line with the highest line priority is an IP line, the process of transmitting code streams in the conference connection between the terminal and the video conferencing platform includes:

Step 41, the upper layer application of the terminal sends the code stream through the IP line;

Step 42, the main IP board sends the code stream to the data processing board;

Step 43, the platform service sends the code stream to be sent to the terminal to the main IP board through the data processing board;

Step 44, after receiving the code stream to be sent to the terminal, the main IP board sends the code stream to be sent to the terminal to the terminal;

Step 45, the terminal upper layer application plays the code stream after receiving it.

According to steps 31-37 and steps 41-45, it can be known that a data processing board is required to process the code stream, and the data processing board can also be called a media resource board, and is used for processing media data. Referring to Fig. 4, both the first frame and the second frame include at least two data processing boards, and the number of data processing boards in each frame can meet the requirements of each video conference process. media resources.

In an example, the data processing boards in each chassis are only connected to the IP boards in the chassis. In other embodiments, the data processing board may also be connected to IP boards in other chassis through a switch, and this embodiment does not limit the connection mode between the data processing board and the IP board.

Correspondingly, the main IP board is also used to: send the data sent by the terminal to the currently connected data processing board, so as to process the data sent by the terminal through the currently connected data processing board; obtain the currently connected data processing board The data sent by the board to be sent to the terminal.

Taking the system architecture shown in Figure 4 as an example, after the video conferencing system is established, the following faults may exist:

1. The main E1 line is faulty;

2. The overall failure of the E1 line;

3. E1 interface or E1 board failure;

4. The main IP board is faulty;

5. The data processing board is faulty.

In order to realize the disaster recovery under the above-mentioned various failure situations, in this embodiment, the terminal is also used to: determine whether a normal line fails; in the case of a normal line failure, re-determine the normal line with the highest line priority, and trigger the execution Steps for data transmission based on the normal line with the highest line priority and the video conferencing platform.

Based on the above content, it can be seen that when a fault occurs and the line is switched, the terminal judges the fault and performs the line switching, and the line switching of one terminal will not affect the line connections of other terminals.

In an example, determining whether the normal line fails includes: determining whether the normal line exists based on a signaling keep-alive mechanism between an upper layer application in the terminal and a platform service in the video conferencing platform Data packet transmission failure: Based on the service detection mechanism between the hardware driver in the terminal and the hardware driver in the video conferencing platform, determine whether there is a physical failure in the E1 line.

The principle of the signaling keep-alive mechanism includes: the upper-layer business of the terminal sends a heartbeat packet to the platform business every first interval to trigger the platform service to send a confirmation feedback to the upper-layer business after receiving the heartbeat packet; If the confirmation feedback is not received, it is determined that a data packet transmission failure occurs on the normal line; if the upper layer service receives the confirmation feedback within the second interval, it is determined that no data packet transmission failure occurs on the normal line.

Wherein, the first interval duration and the second interval duration are adjustable, the first interval durations corresponding to different lines are the same or different, and the second interval durations corresponding to different lines are the same or different.

The principle of the service detection mechanism includes: the terminal hardware driver sends a heartbeat packet to the platform hardware driver every third interval to trigger the platform hardware driver to send a confirmation feedback to the terminal hardware driver after receiving the heartbeat packet; If the confirmation feedback is not received for a period of time, it is determined that a physical failure has occurred in E1; if the terminal hardware driver receives the confirmation feedback during the fourth interval, it is determined that no physical failure has occurred in the E1 line.

Wherein, the duration of the third interval and the duration of the fourth interval are adjustable, the duration of the third interval corresponding to different lines is the same or different, and the duration of the fourth interval corresponding to different lines is the same or different.

Taking the line priority from high to low as follows: the E1 line connected to the main E1 interface (main IE line), the E1 line connected to the standby E1 interface (standby IE line), and the IP line as an example, the In the case of a fault, re-determine the normal line with the highest line priority, including the following situations:

The first method: if the current E1 line connected to the main E1 interface is a normal line and a line fault occurs, and the E1 line connected to the standby E1 interface is not faulty, then determine that the E1 line connected through the standby E1 interface is the line priority Highest normal line. That is, if the main E1 line is connected according to the priority order and the main E1 line is found to be faulty, based on the priority order, it is confirmed whether the backup E1 line is normal, and if it is normal, the backup E1 line is regarded as a normal line. At this time, the data sent by the terminal is transmitted to the main IP board for processing through the E1 board connected to the standby E1 interface; the data to be sent to the terminal is transmitted to the E1 board connected to the standby E1 interface through the main IP board, Send to the terminal through the E1 line connected through the standby E1 interface.

Specifically, referring to the failure of the main E1 line shown in Figure 5, after using the main E1 line to establish a conference connection, the terminal detects a data packet transmission failure based on the signaling keep-alive mechanism; Fault: The terminal tries to use the standby E1 line to register the terminal IP address to the standby E1 board according to the set line priority order, and the standby E1 board sends the terminal's signaling and code stream to the main IP board through the switch to complete disaster preparedness. Data transfer paths are indicated by bold arrows.

The duration of disaster recovery recovery is determined based on the fault detection duration of the signaling keep-alive mechanism and service detection mechanism.
