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 invention: 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.
The devices involved in the video conference may include a switching control device, an autonomous server, and a participant terminal. The switching control equipment can be in communication connection with at least one autonomous server, and one autonomous server can be in communication connection with at least one participant terminal.
For the video conference in the video network, the switching Control device and the autonomous server may perform communication bidirectional communication based on an Internet Protocol, such as an IP (Internet Protocol, Protocol for interconnection between networks) and a TCP (Transmission Control Protocol). The autonomous server and the autonomous server can be communicated with each other in a two-way mode based on the video networking protocol. The autonomous server and the participating terminals can perform communication bidirectional communication based on the video networking protocol.
The video network terminal can be various Set Top Box (STB) and PC (personal computer) based on the video network protocol, the video network terminal can be normal service when being registered in the video network, and the video network terminal can obtain the terminal number, MAC (Media Access Control) address and other information in the video network after being successfully registered.

The switching control device may communicate with one or more autonomous servers based on an internet protocol to establish a connection if an operation of switching a speaking party is to be performed in the video conference, and join the autonomous servers after the connection is established in the video conference.
An object of the embodiments of the present invention is to frequently switch speakers in a video conference, so as to monitor whether the video conference has problems of functional defects, memory overflow, and the like. Therefore, a plurality of switching talker commands may be set in advance. The specific information of the instruction to switch the speaking party may include information of the speaking participant terminal and the like. The information of the talk burst participant terminal may include a terminal number, a MAC address, etc. of the talk burst participant terminal. The type of the switch speaker instruction may include switching the chairman to be the speaker, switching the designated participant to be the speaker, switching the two participants to be speakers of each other, polling each participant to be the speaker, and so on.
And the switching control equipment sends the switching speaking party instructions to the corresponding autonomous servers one by one. The corresponding autonomous server is an autonomous server to which the speech participant terminal corresponding to the information of the speech participant terminal included in the speech party instruction is connected.
In one implementation, the switching control device communicates with the autonomous server based on an internet protocol, so that when a switching talker command is sent, the switching control device adds an internet protocol header to the switching talker command, and encapsulates the switching talker command into an internet protocol command packet based on the internet protocol. The IP header may include information such as an IP address (source address) of the handover control device, and an IP address (destination address) of an autonomous server to which the talk-participating terminal is connected, the IP address corresponding to the information of the talk-participating terminal. The switching control device may transmit the internet protocol instruction packet to the corresponding autonomous server based on the internet protocol. For example, the internet protocol instruction packet may be sent to the autonomous server by using TCP Socket communication or the like.
Therefore, the step of sending the plurality of preset switching talker commands to the corresponding autonomous servers one by the switching control device may specifically include: and the switching control equipment sends the plurality of Internet protocol instruction packets to the corresponding autonomous servers one by one.
And when receiving a command for switching the speaking party, the autonomous server forwards the command for switching the speaking party to the speaking participant terminal corresponding to the information of the speaking participant terminal, so that the speaking participant terminal responds to the command to speak.
Corresponding to the implementation manner that the switching control device encapsulates the switching talker command into an internet protocol command packet based on an internet protocol and sends the internet protocol command packet to the corresponding autonomous server, the autonomous server communicates with the participant terminal based on a video networking protocol, and therefore the step that the autonomous server forwards the switching talker command to the talker participant terminal corresponding to the information of the talker participant terminal may specifically include: and when receiving an internet protocol instruction packet, the autonomous server converts the internet protocol instruction packet into a video networking protocol instruction packet, and forwards the video networking protocol instruction packet to the speaking participant terminal corresponding to the information of the speaking participant terminal after conversion.
In an implementation, the step of converting the internet protocol command packet into the internet protocol command packet by the autonomous server may include: the autonomous server analyzes the Internet protocol command packet to obtain the command of switching the speaking party; and the autonomous server adds a video networking protocol packet header to the switching speaking party instruction, and encapsulates the switching speaking party instruction into the video networking protocol instruction packet based on a video networking protocol. The packet header of the video networking protocol may include information such as a MAC address (source address) of the autonomous server, a MAC address (destination address) of the conference-speaking terminal, and the like. The parsing, by the autonomous server, of the internet protocol command packet to obtain the talker switching command may include: the autonomous server analyzes (decapsulates) the internet protocol command packet, deletes the internet protocol packet header of the internet protocol command packet, and extracts the encapsulated speak party switching command from the internet protocol command packet.
The autonomous server processes the related data based on the video networking protocol, so that in order to ensure that the autonomous server can correctly analyze the command for switching the speaking party, the switching control device and the autonomous server may agree in advance that the format for switching the speaking party command is a format based on the video networking protocol (such as a binary format, etc.), and therefore, in the embodiment of the present invention, the command for switching the speaking party is a command in an agreed in advance format based on the video networking protocol.
After the switching speaking party instruction is obtained by analyzing from the internet protocol instruction packet, the autonomous server analyzes the switching speaking party instruction according to the switching speaking party instruction (namely, a format based on a video networking protocol agreed in advance), and extracts information of the speaking participant terminal from the switching speaking party instruction. And the autonomous server can determine the corresponding speech participant terminal according to the information of the speech participant terminal included in the speech party switching instruction, and sends the video networking protocol instruction packet to the speech participant terminal corresponding to the information of the speech participant terminal based on the video networking protocol.
After receiving the instruction packet for switching the speaking party, the speaking participant terminal responds to the instruction for switching the speaking party and knows that the speaking participant terminal is used as the speaking party, so that the speaking participant terminal collects audio and video, encodes the audio and video to obtain speaking data, and returns the speaking data to the autonomous server based on a video networking protocol. The talk data may include an audio stream and a video stream.
If the autonomous server receives the speech data returned by the speech participant terminal in response to the instruction of switching the speech party, the autonomous server can determine that the switching is successful, so that a notification of successful switching can be generated, and the notification of successful switching is sent to the switching control equipment, so that the switching control equipment is notified that the instruction of switching the speech party is successful.
The switching control device receives the switching success notification and then learns that the switching is successful for the switching speaker instruction transmitted before, so that the switching control device can acquire the information of the viewing participant terminal and generate the viewing notification including the information of the viewing participant terminal. The information of the viewing participant terminal may include a terminal number, an MAC address, a channel identifier for receiving speech data, and the like of the viewing participant terminal. Of course, the viewing notification may include information such as the address of the comment data of the comment participant terminal.
The switching control device transmits a viewing notification to the autonomous server to notify the autonomous server to begin forwarding the talk data.
And step 505, the autonomous server forwards the speech data to the viewing participant terminal corresponding to the information of the viewing participant terminal.
And after receiving the watching notice, the autonomous server analyzes the watching notice to obtain the information of the watching participant terminal included in the watching notice, the autonomous server can determine the corresponding watching participant terminal according to the information of the watching participant terminal, and forwards the speech data to the watching participant terminal corresponding to the information of the watching participant terminal based on a video networking protocol. And after receiving the speech data, the watching participant terminal decodes and plays the speech data.
In the process of executing the flow, the autonomous server can also monitor whether an error occurs in real time.
For example, if the viewing participant terminal successfully receives the speech data and successfully views the speech data, a viewing success notification is returned to the autonomous server; if the watching participant terminal successfully receives the speech data, but the watching participant terminal fails due to the current online and other reasons, a watching failure notice is returned to the autonomous server; and if the watching participant terminal does not successfully receive the speaking data, no notification is returned to the autonomous server. If the autonomous server receives a successful watching notification returned by the watching participant terminal, the autonomous server can determine that no error occurs; if the autonomous server receives a watching failure notice returned by the watching participant terminal, an error can be determined to occur, wherein the type of the error is that the watching participant terminal successfully receives but fails to watch; if the autonomous server does not receive the notification returned by the watching participant terminal within the set time, the autonomous server can determine that an error occurs, and the type of the error is that the watching participant terminal fails to receive.
When an error occurs, the autonomous server generates error information. The error information may include information of the viewing participant terminal in which the error occurred, the type of the error, and the like. And the autonomous server sends the error information to the switching control equipment, and the switching control equipment stores the error information so as to analyze and improve the video conference condition according to the error information in the following.
In the embodiment of the invention, the operation of switching the speaking party is executed for multiple times, the error information is recorded when the error occurs after the switching, the switching control equipment manages the error information uniformly, and the error information can be known in which link the error occurs, what error occurs and the like. Therefore, whether the video conference has the conditions of function defects, memory overflow and the like can be known according to the error information, so that the conditions are solved, and the normal operation of the video conference is guaranteed.
Example two
Referring to fig. 6, a flowchart illustrating a video conference processing method according to a second embodiment of the present invention is shown.
The video conference processing method of the embodiment of the invention can comprise the following steps:
For the specific description of step 601, reference may be made to the related description of step 501 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
For the specific description of step 602, reference may be made to the related description of step 502 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
For the specific description of step 603, reference may be made to the related description of step 503 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
For the detailed description of step 604, reference is made to the related description of step 504 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
And 605, the autonomous server forwards the speech data to the viewing participant terminal corresponding to the information of the viewing participant terminal.
In implementation, if the viewing participant terminal is connected to the current autonomous server (that is, the autonomous server connected to the viewing participant terminal), the current autonomous server forwards the speech data to the viewing participant terminal. If the watching participant terminal is connected with other autonomous servers, the current autonomous server sends the speech data to the autonomous server connected with the watching participant terminal, and then the autonomous server connected with the watching participant terminal sends the speech data to the watching participant terminal.
In an optional implementation manner, after the autonomous server forwards the speech data to the viewing participant terminal corresponding to the information of the viewing participant terminal, it may also monitor whether the speech data is forwarded completely. The completion of the forwarding of the speaking data means that the speaking data already forwarded by the autonomous server is forwarded to all the watching participant terminals. And the autonomous server generates a watching completion notification when the forwarding is completed and returns the watching completion notification to the switching control equipment.
The watching completion notification is used for indicating that the instruction of switching the speaking party for the current time has completed the related operation, so that the switching control device can know that the autonomous server has completed the related operation for the instruction of switching the speaking party for the current time when receiving the watching completion notification, and therefore the switching control device can send the instruction of switching the speaking party next time to the corresponding autonomous server and continue to circularly execute the steps.
For the specific description of step 606, reference is made to the related description of step 506 in the first embodiment, and the embodiment of the present invention is not discussed in detail herein.
After the autonomous server forwards the instruction for switching the speaking party to the speaking participant terminal corresponding to the information of the speaking participant terminal in step 602, if the speaking participant terminal does not receive the instruction for switching the speaking party due to reasons such as network disconnection, or if the switching of the speaking participant terminal fails, the speaking participant terminal does not return speaking data like the autonomous server. Therefore, if the autonomous server does not receive the speech data returned by the speech participant terminal in response to the instruction of switching the speech party, a switching failure notification is generated and sent to the switching control equipment.
After receiving the switching failure notification, the switching control device learns that the switching is failed, so that the switching control device does not send a viewing notification to the autonomous server any more, and does not execute the steps after step 604 any more.
The embodiment of the invention can automatically detect whether the video conference is stable, has functional defects and memory overflow after the video conference circularly switches the speakers in various complex service scenes.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
