2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present application: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Based on the characteristics of the video networking, one of the core concepts of the embodiment of the application is provided, the conference management platform generates a forced call signaling according to a conference post-checking instruction sent by the post-checking system, the forced call signaling triggers an audio and video automatic acquisition protocol, so that a camera and a microphone of a post-checked conference terminal are forcibly turned on, the conference management platform can acquire audio and video stream data automatically acquired by the post-checked conference terminal and forward the audio and video stream data to the post-checking conference terminal, the post-checking conference terminal can acquire the audio and video stream data of the post-checked conference terminal without the consent of the post-checked conference terminal, and the post-checking purpose is achieved.

Example one

Referring to fig. 5, a flowchart of steps of embodiment 1 of a method for checking posts of participating terminals according to the present application is shown, in this embodiment of the present application, the method may be applied to a video network, where the video network includes a post checking system 602, a conference management platform 601 connected to the post checking system 602, and a plurality of conference terminals 603 connected to the conference management platform 601, and each conference terminal 603 has a camera and a microphone.

Fig. 6 is a diagram illustrating an application environment of a method for checking the participating terminals according to an embodiment of the present application. The post-checking system 602 may be understood as a system that can manage a plurality of conference terminals 603, and the post-checking system 602 may be deployed on each conference terminal 603 or on a separate server; the conference terminal 603 may be a PC, an android phone, or the like; the conference management platform 601 can be understood as a service platform capable of managing and monitoring the video conference of the conference terminal 603.

The method for checking the sentry of the participant terminal in the embodiment of the application specifically comprises the following steps:

step 501, the conference management platform 601 receives a conference post-checking instruction sent by the post-checking system 602.

And the conference post searching instruction comprises a post searching terminal number and a first participant terminal number.

In practice, during a video conference, a user may select a conference terminal 603 to participate on a page of the post-checking system 602, and then select a conference initiator therein as a post-checking conference terminal, and the remaining conference terminals 603 as objects to be checked. The post searching terminal number may be a number or a code that identifies a certain conference terminal 603 as a post searching conference terminal, and the first participant terminal may be a number or a code that identifies a certain conference terminal 603 as a participant conference terminal 603.

Step 502, the conference management platform 601 generates a first forced call signaling for the conference post-checking instruction, and sends the first forced call signaling to the first conference participating terminal corresponding to the first conference participating terminal number.

The first conference participating terminal is used for triggering a prestored first audio and video automatic acquisition protocol when receiving the first forced call signaling, and automatically starting a camera and a microphone to acquire first audio and video stream data based on the triggered first audio and video automatic acquisition protocol.

In the video networking conference, the forced call signaling may be an operation script for the conference management platform 601 to call the conference terminal 603 to enter the conference, when the forced call signaling is sent to the first conference-participating conference terminal, a pre-stored audio/video automatic acquisition protocol may be started, and when the audio/video automatic acquisition protocol is started, the camera and the microphone may be automatically turned on without the consent of the first conference-participating conference terminal, that is, without the consent of the user of the first conference-participating conference terminal, and the audio/video data may be automatically acquired by the camera and the microphone.

In practice, when each conference terminal 603 is connected to the conference management platform 601, that is, the audio/video automatic acquisition protocol may be prestored in each conference terminal 603, and the audio/video automatic acquisition protocol may be a 8714 protocol in the video network, that is, once the conference terminal 603 receives a forced call signaling, the 8714 protocol is started, and a camera and a microphone of the conference terminal 603 are forcibly turned on.

In step 503, the conference management platform 601 receives the first audio and video stream data sent by the first participant conference terminal, and sends the first audio and video stream data to the post-checking conference terminal corresponding to the post-checking terminal number.

According to the embodiment of the application, the camera and the microphone of the first participating conference terminal are forcibly started through the forced calling signaling sent by the conference management platform 601 to collect audio and video stream data, and the audio and video stream data are forwarded between the first participating conference terminal and the post checking conference terminal through the conference management platform 601, so that the post checking conference terminal can receive the audio and video data of the first participating conference terminal, and the audio and video data of the post checking conference terminal cannot be seen by the first participating conference terminal, and the purpose of performing post checking in a video conference is achieved.

As an optional example of the embodiment of the present application, the conference management platform 601 further includes a database, where a first terminal list of the plurality of conference terminals 603 is prestored in the database, and the first terminal list includes terminal numbers and online status information of the conference terminals 603.

The online status information of the terminal list in the database can be divided into offline information and online information.

As an optional example of the embodiment of the present application, before step 501, the following steps may also be included:

the conference management platform 601 extracts all online conference terminal 603 numbers from the first terminal list based on the online state information, generates a second terminal list aiming at all the conference terminal 603 numbers, and sends the second terminal list to the post checking system 602; the post-checking system 602 is configured to generate a conference post-checking instruction according to the first selection operation for the second terminal list.

Specifically, the post-checking system 602 may display the second terminal list on a web page, and the user may select the target conference terminal 603 by means of a click operation, a touch operation, or the like. The generated conference post-checking instruction may carry a post-checking identifier of the post-checking terminal number and a post-checked identifier of the first participating terminal number, that is, when a selection operation is performed on the terminal list, a certain conference terminal 603 may be set as a post-checking conference terminal, and another conference terminal 603 may be set as a participating conference terminal 603, so that the conference management platform 601 may confirm the post-checking conference terminal corresponding to the post-checking terminal number through the post-checking identifier, and may confirm the corresponding first participating conference terminal through the first participating terminal identifier.

In this embodiment of the application, the conference management platform 601 puts all online conference terminals 603 into the second terminal list, so that the terminal list acquired by the post checking system 602 is for all online conference terminals 603, and the problem of wasting video networking resources due to performing post checking on some offline conference terminals 603 is avoided.

As an optional example of the embodiment of the present application, after step 503, the following step may be further included:

in step 504, when receiving the participant switching instruction sent by the post checking system 602, the conference management platform 601 stops sending the first audio/video stream data to the post checking conference terminal corresponding to the post checking terminal number.

The participant switching instruction is generated by the sentry searching system 602 according to a second selection operation for the second terminal list, and the participant switching instruction includes a second participant terminal number.

In practice, after the post checking of the first participating conference terminal is completed, the post checking system 602 may switch to the next conference terminal 603 to be checked for post checking, where the second selection operation may be understood as a switching operation for the second participating conference terminal, and when the participant switching instruction reaches the conference management platform 601, the conference management platform 601 terminates the audio and video stream data forwarding operation performed between the first participating conference terminal and the post checking conference terminal.

As an optional example of step 504 in the embodiment of the present application, after this step 504, the following step may be further included:

And the first conference participating terminal is used for finishing the first audio and video automatic transmission protocol when receiving the call finishing instruction so as to control the camera and the microphone to be automatically closed.

In practice, the call ending instruction may be an operation script, and when the conference management platform 601 receives the participant switching instruction, the operation script is started, so as to automatically end the first audio/video automatic transmission protocol, so that the first audio/video automatic transmission protocol is in a dormant state, and when the first audio/video automatic transmission protocol is in the dormant state, the starting state of the camera and the microphone of the first participant conference terminal cannot be maintained any more, so that the camera and the microphone are automatically closed along with the dormancy of the first audio/video automatic transmission protocol; the camera and the microphone are still started to collect audio and video stream data when the post checking of the first conference participating conference terminal is finished, so that the privacy of the first conference participating conference terminal is guaranteed to be protected when the post checking is finished, and meanwhile, the situation that the camera and the microphone which are forcibly started occupy an application process after the post checking of the first conference participating conference terminal is finished consume equipment resources of the first conference participating conference terminal is reduced.

Step 506, the conference management platform 601 generates a second forced call signaling for the participant switching instruction, and sends the second forced call signaling to the second participant conference terminal corresponding to the second participant terminal number.

And the second conference participating terminal is used for starting a prestored second audio and video automatic acquisition protocol when receiving the second forced call signaling, and automatically starting a camera and a microphone to acquire second audio and video stream data based on the triggered second audio and video automatic acquisition protocol.

The process of step 505 may refer to the description of step 502, and this step is not described in detail again.

By adopting the operations from step 504 to step 506, the post checking of each participating conference terminal 603 in turn can be realized, so that the pertinence to the post checking of participating conference terminals 603 can be improved.

Step 506, the conference management platform 601 receives the second audio and video stream data sent by the second conference participating conference terminal, and sends the second audio and video stream data to the post checking conference terminal.
