In the related art, before a conference is carried out, a terminal number to be added to the video conference needs to be configured in a video conference system in advance, and a terminal cannot flexibly add or withdraw from the video conference, that is, a user cannot realize the operation of adding or withdrawing from the video conference through interaction with the terminal, so that the user experience is poor.

In order to solve the above technical problem, embodiments of the present invention provide a conference implementing method, apparatus, device and readable storage medium.

As shown in fig. 1, an embodiment of the present invention provides a conference implementation method, which is applied to a scheduling server in a video network, and specifically includes the following steps:

s101: and receiving a conference query request sent by the video networking terminal, wherein the conference query request carries the identity information of the video networking terminal.

In the embodiment of the invention, the video network terminal can generate and send the conference query request to the scheduling server according to the instruction of the user, for example, when the user needs to join or quit a certain conference, the video network terminal can send the query instruction to the video network terminal, and then the video network terminal generates the conference query request.

Or, the video network terminal may also send a conference query request to the scheduling server periodically according to a preset time rule, so that when a user needs to join or quit a certain conference, the cached conference information can be directly obtained from the video network terminal, thereby reducing the response speed of the video network terminal and further improving the user experience.

In this step, the scheduling server may receive a conference query request sent by any connected video networking terminal in the video networking, or may only receive a conference query request sent by a video networking terminal bound in advance.

For example, in an implementation manner, a manner of registering identity information of a video network terminal in a scheduling server may be adopted to implement binding between the scheduling server and the video network terminal, that is, after the scheduling server receives a conference query request, whether the video network terminal sending the conference query request is a bound video network terminal may be determined according to the identity information carried in the conference query request, and if so, the next step of processing is performed.

In addition, in an implementation manner, there are a plurality of scheduling servers in the video network, in this case, the video network may further include a central server, the central server is in communication connection with the plurality of scheduling servers, and the video network terminal needs to register in the central server, so as to implement binding with its corresponding scheduling server.

For example, firstly, a video network terminal sends binding request information to a scheduling server, wherein the binding request information includes identity information of the video network terminal, then, the scheduling server can send the binding request information to a central server, and then, the central server registers the identity information of the video network terminal according to the binding request information and returns a binding result to the scheduling server and the video network terminal.

In this step, the identity information of the video networking terminal may be a serial number of the video networking terminal, an ID of the video networking terminal, or address information of the video networking terminal, and any information that can uniquely determine the video networking terminal may be used as the identity information of the video networking terminal, which is not limited specifically.

S102: and inquiring the state information of the video network terminal in the current ongoing conference in the video network according to the identity information to obtain a state information list of the video network terminal.

In this step, after receiving the conference query request, the scheduling server may query a currently ongoing conference in the video network, and then query the state information of the video network terminal in the currently ongoing conference, thereby obtaining a state information list of the video network terminal.

The state information of the video network terminal in the current ongoing conference at least may include the following: the method comprises the following steps of applying for a meeting, applying for a meeting without examination, applying for a quit by the meeting and not passing the applied quit.

In one implementation, the scheduling server may store conference information of each conference in the video network in advance, and the conference information may include information such as the start time of the conference, so that, after receiving a conference query request, the scheduling server may directly query the current ongoing conference from the local.

Alternatively, the scheduling server may also query the status information list of the terminal in the video network from a central server in the video network. Specifically, firstly, the scheduling server may send the identity information to the central server, then, the central server locally queries a current ongoing conference in the video network, determines state information of the video network terminal in the current ongoing conference, obtains a state information list of the video network terminal, and then sends the state information list to the scheduling server.

S103: and sending the state information list to the video networking terminal.

After receiving the state information list, the video network terminal can display the state information list, so that a user can determine the current ongoing conference in the video network and the state of the video network terminal in the conferences from the video network terminal, and execute corresponding operation according to the self requirement.

S104: and receiving and processing a conference request aiming at the target conference sent by the video networking terminal, and feeding back a processing result to the video networking terminal, wherein the conference request is to join or quit the target conference.

In the embodiment of the invention, the video network terminal can generate a conference request aiming at the target conference according to the instruction of the user and send the conference request to the scheduling server.

In one implementation manner, the scheduling server may implement a conference request sent by the video networking terminal through the central server, and specifically, the scheduling server receives a conference request for a target conference sent by the video networking terminal and sends the conference request to the central server, and then the central server sends the conference request to the scheduling server corresponding to the target conference through the message middleware, and processes the conference request by the scheduling server corresponding to the target conference, and further receives a processing result of the conference request returned by the central server.

Each scheduling server in the video network and the message middleware are always in a linked state, so that after the central server pushes the conference request to the message middleware, the scheduling server can receive the conference request immediately, and the response speed is improved.

As can be seen from the above, in the conference implementation method provided in the embodiment of the present invention, the video network terminal may query the state of the video network terminal itself in the current ongoing conference through the scheduling server, and may send a request for joining or quitting the target conference, so that a user may implement the join or quit operation on the conference through interaction with the video network terminal, thereby improving user experience.

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.

Based on the characteristics of the video network, one of the core concepts of the embodiment of the invention is provided, the video network terminal can inquire the state of the video network terminal in the current ongoing conference through the scheduling server, and can send a request for joining or quitting the target conference, so that the user can realize the operation of joining or quitting the conference through the interaction with the video network terminal.
