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 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.

as a preferred example of the embodiment of the present invention, the call address may include a conference identifier of the target video conference and an internet IP address of the H323 protocol server. For example, the call address may be "internet IP address of H323 protocol server + # # +80+ conference identifier (conference number)", where the conference identifier may be a conference number that an external network device needs to join the video network conference.

And a substep S13 of generating a call instruction according to the call address.

After receiving the call address input by the user, the external network device may encapsulate the call address into a call instruction by using the H323 protocol.

Step 602, sending the call instruction to the H323 coordination server to request to join the target video networking conference;

after the external network device generates the call instruction, the call instruction may be sent to the H323 protocol conversion server through the H323 protocol, for example, the external network device sends Cs: and sending a setup call instruction to the H323 collaboration server to request to join the target video network conference corresponding to the conference number in the call instruction.

Step 603, if receiving a call connection instruction returned by the H323 protocol conversion server, determining that the target video networking conference is successfully joined.

The call connection instruction is an instruction for the H323 coordination server to determine one or more target video network terminals according to the target video network conference corresponding to the conference identifier, and the received target video network terminals respond to the call instruction after the call instruction is sent to the one or more target video network terminals through the video network server.

Specifically, on the side of the H323 collaboration server, after receiving the call instruction, the call instruction is analyzed to obtain the conference number in the call instruction, so as to determine the corresponding target video networking conference according to the conference number, and obtain the terminal identifier of the video networking terminal included in the target video networking conference, as the terminal identifier of the target video networking terminal.

And then, the H323 protocol conversion server converts the call instruction of the H323 protocol into a call instruction of an Internet of things protocol, wherein the call instruction of the Internet of things protocol carries the terminal identification of the target Internet of things terminal. And the video network server sends the call instruction of the video network protocol to a target video network terminal.

For example, the H323 protocol conversion server receives Cs: after the setup call command, the setup call command is converted into an 8e01callsetup (8e01 call command) and sent to the video network server, and the video network server converts the 8e01call command into an 8e02 call connection command and then sends the 8e02 call connection command to the called target video network terminal.

And at the target video network terminal, after receiving the 8e02 call connection instruction, the target video network terminal rings, and after answering the ring, the target video network terminal completes the connection process of conference-in communication, and at the moment, the target video network terminal replies the 8e01call connection instruction to the video network server. The video network server converts the call connection command of 8e01 into 8e02 and sends the 8e02 to the H323 protocol conversion server, and the H323 protocol conversion server converts the call connection command of 8e02 into a call connection command of H323 protocol and replies the call connection command to the extranet device, for example, the call connection command of H323 protocol may be expressed as Cs: callprocessing, Cs: alerting, Cs: connect to inform the external network device that the session has been successfully entered.

When receiving the call connection instruction, the external network equipment side can judge that the target video network conference is successfully joined, and at the moment, each piece of equipment participating in the conference can see the picture of the external network equipment.

In a specific implementation, after the extranet device successfully joins the video conference by means of active call, the extranet device may send a terminalCapabilitySet (terminal capability set setting) message to the H323 collaboration server, where the message is a set of audio and video transmission capabilities that the H323 collaboration server can support in the conference, and the H323 collaboration server returns a terminalCapabilitySetAck (terminal capability set setting reply message) to respond after setting.

Then, the video network server sends 8704openDecode (protocol instruction 8704 for opening the video network codec) messages to the H323 cooperative server and the target video network terminal, the H323 cooperative server sends 8704open logic channel converted H323 messages to the external network device, and the external network device replies openlogic channel reply messages to open its own audio/video channel.

Subsequently, the audio and video stream is communicated. Through the appointed screen splitting function in the MCU Manager of the webpage version, the video pictures of the participants can be respectively seen at the external network equipment and the target video network terminal.

In a preferred embodiment of the present invention, the following steps may be further included:

and after the target video networking conference is successfully joined, receiving the audio stream and/or the video stream sent by the H323 cooperative conversion server, and playing the audio stream and/or the video stream.

In the specific implementation, after the external network device successfully joins the target video networking conference, the target video networking terminal can send video networking audio/video streams to the video networking server, the video networking server forwards the video networking audio/video streams to the H323 cooperative conversion server, the H323 cooperative conversion server converts the video networking audio/video streams into an H323 protocol, and then sends the H323 protocol to the external network device, and the external network device plays the video networking audio/video streams.

Specifically, the target video network terminal may send the 2002 video stream and the 2001 audio stream to the video network server, and the video network server forwards the 2002 video stream and the 2001 audio stream to the H323 collaboration server. Then, at the H323 collaboration server, the 2002 video stream is converted into an H264 video stream, and the 2001 audio stream is converted into a G711 audio stream (or an AAC audio stream, which may be applied to the AAC audio stream as described below by taking the G711 audio stream as an example), and then, the H323 collaboration server encapsulates the H264 video stream and the G711 audio stream into an RTP protocol stream after performing mixing processing, sends the RTP protocol stream to an MCU (Microcontroller Unit) of the H323 collaboration server, and finally forwards the RTP protocol stream to the external network device for playing.

Correspondingly, in another preferred embodiment of the present invention, the embodiment of the present invention may further include the following steps:

and sending an audio stream and/or a video stream to the H323 cooperative server.

Specifically, the external network device may send an RTP protocol stream to the H323 cooperative conversion server, the H323 cooperative conversion server decapsulates the RTP protocol stream into an H264 video stream and a G711 audio stream, mixes the H264 video stream and the G711 audio stream, encapsulates the mixed H264 video stream and the G711 audio stream into a 2002 video stream and a 2001 audio stream, and sends the 2002 video stream and the 2001 audio stream to the video networking server, and the video networking server sends the two streams to the target video networking terminal, so that the target video networking terminal can see the audio and video stream mixed after the group meeting.

In one embodiment, the mixing process is as follows:

the H323 co-transformation server mixes the H264 video stream and the G711 audio stream sent by the external network equipment with the H264 video stream and the G711 audio stream which are transferred by the H323 co-transformation server and are transferred by the video networking server into a multi-split-screen stream through a video mixing module or an audio mixing module.

Of course, the embodiment of the present invention is not limited to the above mixing process, and those skilled in the art may perform the mixing process in other manners.

In a preferred embodiment of the present invention, when the external network device wants to quit the target video networking conference, the embodiment of the present invention may include the following steps:

generating a command for closing the session; and sending the session closing instruction to an H323 cooperative conversion server, wherein the H323 cooperative conversion server is used for generating a hang-up instruction based on the session closing instruction and sending the hang-up instruction to one or more target video network terminals.

As an example, the close session command may include a Requestchannelclose command, endSessionCommand, releasecomple (complete release), closeloghannel, and the like.

Specifically, if the extranet device wants to exit the target video conference, it may first send a requestchannelcllose to the H323 protocol conversion server, after the H323 protocol conversion server receives the request, it replies a requestchannelseack (request to close the channel reply), and then the extranet device sends an endSessionCommand, a releasecomple, a closeogrhannel to the H323 protocol conversion server to make a hang-up request.

After receiving the command of closing the session, the H323 protocol conversion server sends 8e01 handoff request to the internet of view server, the internet of view server converts the 8e01 handoff request into 8e02 handoff request to be sent to the target internet of view terminal, the target internet of view terminal executes the hang-up operation after receiving the 8e02 handoff request, returns 8e01 hang-up reply to the internet of view server, and the internet of view server converts the 8e01 hang-up reply into 8e02 hang-up reply to the H323 protocol conversion server.

The video network server then sends 8704closeDecode (8704 to turn off codec) to the H323 collaboration server and the target video network terminal, respectively, to close the logical channel.

After the logical channel is closed, the H323 collaboration server respectively replies messages such as endSessionCommandAck (closing session reply), releaseCompleteAck (complete release reply), and closeloghannelack (closing logical channel reply) to the external network device, thereby completing the process of the external network device exiting the video networking conference.
