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.

It is understood that the embodiment of the invention can be applied to internet meetings and video networking meetings.

Referring to fig. 5, an embodiment of the present invention provides a method for synchronizing conference control rights, which may specifically include steps 501 and 505:

step 501: and when the first conference control terminal of the target conference is detected to be abnormal, acquiring the preset identifier of the second conference control terminal.

Illustratively, embodiments of the present invention may be used in conference control servers; the conference control server can directly acquire the conference state information of the target conference from each participant terminal or acquire the conference state information of the target conference from the conference control server; the conference control server may also store a control key of the conference, an identifier of the first conference control terminal, an identifier of the second conference control terminal to be selected, and the like in advance.

In this embodiment of the present invention, the first conference control terminal or the second conference control terminal may be a mobile phone terminal, a PC (computer) terminal, a Web (Web page) terminal, or the like.

The first conference control terminal may obtain the conference state information through the conference control server through a preset conference control program such as a conference control client, a web page, and the like, so as to monitor a target conference, or may send a preset conference control instruction (for example, to specify a conference speaker, end a conference, issue a conference announcement, and the like) to the conference control server, so as to control the target conference.

When the first conference control terminal is damaged, poisoned, crashed in the conference control program, and the network connection fault occurs, the control right to the target conference is lost; and most conference systems of the target conference are based on a WebService protocol, a conference instance is packaged at the lower layer to control a conference flow, and if a handle of the conference instance disappears due to damage of a conference control terminal or abnormity of a conference control program, the target conference is synchronously terminated.

In the embodiment of the present invention, the communication state of the first conference control terminal may be continuously detected by a plurality of detection methods such as a heartbeat packet, which are not described herein again.

In order to avoid this problem, the conference control server may store in advance an identifier of the second conference control terminal, which is an alternative identifier of the second conference control terminal, in advance, where the identifier may be an IP address, a number, or the like.

Step 502: and sending a target conference control request to the second conference control terminal according to the identifier of the second conference control terminal.

According to the identifier of the second conference control terminal, communication can be established with the second conference control terminal, and then a target conference control request is sent, and the second conference control terminal is expected to take over the target conference; the target conference control request may include information such as a name of the conference, a participant terminal, and a conference time.

It can be understood that, when the second conference control terminal receives the target conference control request, the target conference control request may be parsed by a preset conference control program or a conference application, etc.; if the user of the second conference control terminal agrees to take over the target conference, returning a response to the target conference control request through operation of the conference control program or the conference application and the like; if the user does not agree, no response may be returned.

Of course, in the embodiment of the present invention, the second conference control terminal may directly return a response after receiving the target conference control request without a user's consent. The second conference control terminal may automatically perform a preparation operation of taking over the conference control right after receiving the target conference control request.

Step 503: and acquiring the control key and the conference state information of the target conference.

In the embodiment of the present invention, the control right of the target conference may be specifically embodied in two aspects: one is to know conference state information of a target conference, and the other is to be able to control the conference by sending a conference control instruction to a conference control server. The control key is used to identify that the terminal corresponding to the conference control instruction sent to the conference control server is a conference control terminal having legal control right for the target conference. Therefore, the conference control server can acquire the control key and the conference state information of the target conference to send to the second conference control terminal.

The control key may be generated by the conference control server according to the target conference, may be transmitted to the conference control server by a terminal that establishes a conference, or may be generated in another manner.

The conference control server can acquire the conference state information through a conference server; the conference state information may include, but is not limited to, the number of the participant terminals, the identification of each participant terminal, the participant state (e.g., online, offline, speaking, etc.) of each participant terminal, the authority (e.g., host, speaker, general audience, etc.) of each participant terminal, the audio/video stream of the target conference, etc.

Step 504: and when receiving a response to the target conference control request transmitted by the second conference control terminal, transmitting the control key and the conference state information to the second conference control terminal.

When a response to the target conference control request sent by the second conference control terminal is received, the second conference control terminal is normal in communication with the conference control server, and preparation for taking over the target conference is made, and the control key and the conference state information sent by the second conference control terminal are sent to the second conference control terminal, so that taking over of the conference control right is achieved.

It can be understood that, when receiving the control key and the conference state information, the second conference control terminal may analyze the conference state information through a preset conference control program or a conference application, and display the conference state information, so that a user can obtain a state of a target conference; and storing the control key. The second conference control terminal may return response information including the control key to the conference control server to notify the conference control server; the response message may include a conference control command or may not include a conference control command.

Step 505: and when receiving response information which is sent by the second conference control terminal and contains the control key, determining that the conference control right is synchronous.

It can be understood that, when receiving the response message including the control key sent by the second conference control terminal, the conference control server may confirm that the second conference control terminal has acquired the control key, has the capability of sending a control instruction including the control key, may control the target conference, and then determines that the conference control right is synchronized.

In this embodiment of the present invention, after the step 503 of obtaining the control key and the conference state information of the target conference, the method further includes: judging the participation state of a preset participation terminal corresponding to the target conference according to the conference state information; and if the preset participating terminal is in the non-participating state, pulling the preset participating terminal into the target conference through the conference scheduling server.

Generally, there are preset participant terminals like a host, a chairman, etc. in a target conference, and if the preset participant terminals do not participate in the conference, the conference is likely to be difficult to proceed. Particularly, the target conference may be synchronously terminated due to an abnormality of the first conference control terminal, and the preset conference terminal may be disconnected from the target conference after the target conference is terminated and does not participate in the conference again, so that the conference control server may determine the conference state of the preset conference terminal according to the conference state information. It can be understood that the conference control server stores the identifier of the predetermined participant terminal, so as to determine the identity of the predetermined participant terminal.

And if the preset participating terminal is in the non-participating state, establishing communication connection with the participating terminal by using the identifier of the preset participating terminal through a conference scheduling server, and carrying out interaction on conference data of the target conference, namely pulling the preset participating terminal into the target conference.

The embodiment of the invention has the following advantages:

in the embodiment of the invention, after the first conference control terminal is abnormal, the second conference control terminal is contacted, the taking over of the target conference is realized by sending the conference state and the control key, and the synchronization of the conference control right of the target conference is determined by the response information which is returned by the second conference control terminal and contains the control key.

Referring to fig. 6, an embodiment of the present invention provides a method for synchronizing control right of a conference, which is applied to a video network conference, and specifically includes steps 601-607:

step 601: and when the first conference control terminal of the target conference is detected to be abnormal, acquiring the preset identifier of the second conference control terminal.

Referring to fig. 7, in the embodiment of the present invention applied to the video networking conference, a conference control server 702 may be connected to a first conference control terminal 701 through an internet protocol, and connected to at least one video networking server 704 through a video networking protocol; the video network server 704 is connected with at least one video network terminal 705 (namely a participating terminal) through a video network protocol; when the conference control server 702 detects that the first conference control terminal 701 is abnormal, it may establish a connection with the second conference control terminal 703 through an internet protocol.

In the video networking conference, most of all the participating terminals are video networking terminals, and certainly, internet terminals also exist, so that a coordination server exists in the video networking conference system to realize data interaction between the video networking and the internet.

In a specific implementation, each video network terminal may be a set-top box (STB), commonly referred to as a set-top box or set-top box, which is a device that connects a tv set to an external signal source and converts compressed digital signals into tv content for display on the tv set.

Generally speaking, the set-top box can be connected with a camera and a microphone, and is used for collecting target conference data such as video data and audio data and sending the target conference data to the video networking server; and target conference data sent by the video networking server can be received and connected with the television to play the target conference data such as video data, audio data and the like.

However, in the video networking terminal, a conference control program or a conference control application is constructed based on a video networking protocol to flexibly send a conference control instruction, so that various possible emergent conditions are met, and the video networking terminal is too high in cost and difficult to implement. Therefore, in the embodiment of the present invention, the second conference control terminal may be an internet terminal, such as a PC terminal, a mobile phone terminal, a Web terminal, and the like.

Similarly, the conference control server has a protocol function (for example, has a dual network card), and can realize conversion between video networking data and internet data.

Of course, in the embodiment of the present invention, the participating terminal may not be limited to the video networking terminal, but may also include an internet terminal; the internet terminal can be connected with the video network server through a protocol conversion server; and will not be described in detail herein.

Step 602: and sending a target conference control request to the second conference control terminal according to the identifier of the second conference control terminal.

Optionally, the step 602 of sending the target conference control request to the second conference control terminal according to the identifier of the second conference control terminal may include:

and if the second conference control terminal is of a second type, sending a target conference control request to the second conference control terminal through a WebService protocol.

WebService is a cross-programming-language and cross-operating-system-platform remote calling technology, and has the following advantages: the system has the advantages of cross-firewall communication, convenience in application program integration, suitability for b2b (Business-to-Business, data interaction between enterprises through a private network or the Internet) integration, and capability of realizing software and data reuse.

TCP (Transmission Control Protocol) is a connection-oriented, reliable transport layer communication Protocol based on a byte stream. In the simplified OSI (Open System Interconnection) model of computer networks, it performs the functions specified by the fourth layer transport layer.

In this embodiment of the present invention, the identifier of the second conference control terminal may be an IP (Internet Protocol) address. The conference control server and the second conference control terminal establish internet connection for communication through the IP address of the conference control server and the IP address of the second conference control terminal.

The first type can be a PC terminal and the like; the second type may be a mobile phone end and a Web end (Web program). Compared with a WebService protocol, the TCP/IP protocol is adopted to communicate with the second conference control terminal, so that the second conference control terminal can be more stable, but the resource overhead is larger; therefore, the TCP/IP protocol is suitable for terminals with better resource performance, such as a PC terminal and the like; the WebService protocol is suitable for a mobile phone end, a Web end and the like.

The embodiment of the invention can realize the control of the conference control terminals of different platforms to the same target conference through various conference control interfaces, such as TCP/IP protocol, WebService protocol and the like.

Referring to fig. 8, in the embodiment of the present invention, a unified conference agent layer (corresponding to a target conference) may be added on the basis of an original video networking conference service layer, and a unique conference id (i.e., a control key of the target conference) is generated as an external operation medium of a conference instance, so that a handle of the conference instance is included in a conference agent mode, and a conference agent can monitor a state of the conference; and the function package of the conference control right synchronization is carried out by utilizing the WebService technology and the TCP/IP on the conference agent layer, and the client (corresponding to the conference control terminal) can carry out the control right synchronization according to the conference id.

Step 603: and acquiring a control key of the target conference.

Step 604: and acquiring first conference state information under the video networking protocol of each video networking terminal participating in the target conference through the video networking server of the target conference.

Based on the characteristics of the video network, the conference control server and each video network server establish video network connection for communication through the MAC address (physical address) of the conference control server and the MAC address of each video network server. The video network servers can be node servers in the video network.

In this practical application, the video network is a network with a centralized control function, and includes a master control server (such as the above video network server) and a lower level network device, where the lower level network device includes a terminal, and one of the core concepts of the video network is that a table is configured by the master control server to notify the switching device of a downlink communication link for a current service, and then a packet is transmitted based on the configured table.

Namely, the communication method in the video network includes:

the main control server configures a downlink communication link of the current service;

and transmitting a target data packet (such as a data packet containing the first conference state information) to a target terminal (such as the conference control server) according to the downlink communication link.

In the embodiment of the present invention, configuring the downlink communication link of the current service includes: informing the switching equipment related to the downlink communication link of the current service to allocate a table;

For the unicast communication service in the access network, the step of configuring the downlink communication link of the current service by the master server may include the following steps:

in sub-step S11, the main control server may receive a service request protocol packet (for example, a request for conference state information of a target conference sent by the conference control server) sent by the source terminal, and obtain downlink communication link information of the current service, where the downlink communication link information includes downlink communication port information of the main control server and the access switch participating in the current service;

in the substep S12, the main control server sets a downlink port to which a packet of the current service is directed in a packet address table inside the main control server according to the downlink communication port information of the control server; sending a port configuration command to a corresponding access switch according to the downlink communication port information of the access switch;

in sub-step S13, the access switch sets the downstream port to which the packet of the current service is directed in its internal packet address table according to the port configuration command.

For the multicast communication service in the access network, the step of the master server obtaining the downlink communication link information of the current service may include the following sub-steps:

in the substep S21, the main control server receives a service request protocol packet sent by the source terminal, wherein the service request protocol packet includes service type information, service content information and an access network address of the target terminal; wherein, the service content information comprises a service number;

step S22, the main control server extracts the access network address of the source terminal in the preset content-address mapping table according to the service number;

in the substep of S23, the main control server obtains the multicast address corresponding to the source terminal and distributes the multicast address to the target terminal; and acquiring the communication link information of the current multicast service according to the service type information and the access network addresses of the source terminal and the target terminal.

In the embodiment of the present invention, both the source terminal and the target terminal may be the conference control server; the conference control server may send a service request protocol packet of conference state information for the target conference to the video networking server (corresponding to the main control server); the video network server can analyze the service request protocol packet and search each video network terminal corresponding to the target conference according to the target conference in the service request protocol packet; and acquiring the recorded conference state information of each video network terminal and sending the conference state information to the conference control server.

That is, the conference control server can be regarded as a video network terminal in the video network, and has a video network terminal number and a corresponding MAC address; when accessing the video network, the validity of the conference control server also needs to be verified through the corresponding relationship between the preset video network terminal number and the MAC address.

It is understood that there may be a plurality of video network servers connected to the conference control server; therefore, the conference control server can receive the conference states of the participating terminals sent by the video networking servers and integrate the conference states into the first conference state information.

Step 605: and converting the first conference state information under the video networking protocol into second conference state information under the Internet protocol.

In the embodiment of the present invention, the conference control server may analyze the first conference state information through a video networking protocol to obtain conference state information such as a conference state of each participant terminal; and repackaging and packaging the conference state information into the second conference state information according to an internet protocol.

Step 606: and when receiving a response to the target conference control request sent by the second conference control terminal, sending the control key and second conference state information under the internet protocol to the second conference control terminal through the internet protocol.

Step 607: and when receiving response information which is sent by the second conference control terminal and contains the control key, determining that the conference control right is synchronous.

When response information sent by the second conference control terminal is received, analyzing the response information through an internet protocol; if the response message includes the control key, determining that the conference control right is synchronous; if the response message does not include the control key, it may be determined that the conference control right is not synchronized.
