However, in this process, the first terminal can only transmit data to each second terminal in sequence through the server, and the first terminal needs to transmit data to the next second terminal after the transmission to one second terminal is completed, so that the efficiency of data transmission is low, and the transmission time is long. Therefore, one of the core concepts of the embodiments of the present invention is that the first terminal transmits all target data to be transmitted to the second terminal to the server at one time, and the server establishes a terminal information list for the second terminal and then performs batch transmission of data according to the terminal information list, thereby achieving batch transmission of data and improving data transmission efficiency. Referring to fig. 1, a flowchart of a first step of a service data transmission method according to an embodiment of the present invention is shown, which may specifically include the following steps:
in the embodiment of the present invention, the first terminal may run an application program, such as a live application program, a recording application program, a monitoring application program, and the like, and the first terminal may transmit data such as live data, audio and video data, and monitoring data to the plurality of second terminals through the application program.
In an example, as shown in fig. 2, which illustrates a schematic diagram of a device communication connection in an embodiment of the present invention, a first terminal and a conference scheduling server are deployed in the internet, the conference scheduling server may send data sent by the first terminal to an autonomous server deployed in an internet of view, and the autonomous server converts data based on an internet protocol format into data based on an internet protocol format and forwards the data to a second terminal.
In a specific implementation, the first terminal may send target data to be sent to the second terminal to the conference scheduling server, and the conference scheduling server may analyze the target data, so as to obtain the service data and the terminal identifier of the second terminal, and which second terminals the service data needs to be sent to.
102, the server generates a terminal information list aiming at the second terminal according to the terminal identification;
in specific implementation, the first terminal transmits target data to be sent to the conference scheduling server at one time, and the conference scheduling server generates a terminal information list for the second terminal according to the terminal identifier in the target data, as shown in table 1, so that the generation of the terminal information list is beneficial to the management of the conference scheduling server on the one hand, and the conference scheduling server can perform data transmission according to the terminal identifier recorded in the terminal information list on the other hand, thereby further improving the efficiency of data transmission.

It should be noted that the embodiment of the present invention includes, but is not limited to, the above examples, and it is understood that, under the guidance of the idea of the embodiment of the present invention, a person skilled in the art may set the form of the list according to practical situations, and the present invention is not limited to this.
In a specific implementation, the conference scheduling server may sequentially send the service data to the autonomous server according to the terminal identifier in the terminal information list, and the autonomous server converts the service data based on the internet protocol format into data based on the video internet protocol format and forwards the data to the second terminal (which may be a video internet terminal) corresponding to the terminal identifier, so that batch data transmission is performed through the conference scheduling server, the efficiency of data transmission is improved, and the time of data transmission is reduced.
In the embodiment of the invention, the server can generate the terminal information list aiming at the second terminal according to the terminal identification in the target data by receiving the target data sent by the first terminal, and sequentially transmit the service data to the second terminal according to the terminal information list, so that the service data is transmitted in batch by establishing the terminal information list in the server and according to the terminal information recorded in the list, the data transmission efficiency is improved, and the data transmission time is reduced.
Referring to fig. 3, a flowchart illustrating a step of a second embodiment of a service data transmission method according to the present invention is shown, and is applied to a server, where the server is in communication connection with a first terminal and at least one second terminal, and specifically includes the following steps:
in a specific implementation, a first terminal deployed in the internet may transmit, through an application (client), service data to be sent to a second terminal and terminal information for the second terminal to a conference scheduling server at one time.
Specifically, the target data may include a terminal identifier of the second terminal, the number of terminals of the second terminal, and transmission sequence information for the second terminal, and the service data transmitted to the second terminal. The first terminal may send the same service data to different second terminals, or send different service data to different second terminals.
after receiving the target data, the conference scheduling server can analyze the target data, so as to obtain the terminal identification, the number of terminals and the sending sequence information. The terminal identification and quantity information may then be used to generate a list of terminal information that matches the transmission sequence information.
In a specific implementation, the service data sent by the first terminal to the conference scheduling server corresponds to a sequence information, for example, the service data is sent to the first terminal, the second terminal, the third terminal, and so on in sequence. The conference scheduling server may generate a terminal information list matched with the sequence information by using the terminal identifier and the quantity information, so that by generating the terminal information list, on one hand, the conference scheduling server is favorable for managing the terminal information, and on the other hand, the conference scheduling server may perform data transmission according to the terminal identifier recorded in the terminal information list, thereby further improving the efficiency of data transmission.
in the embodiment of the present invention, the target data may further include status information and a data transmission type. The data transmission type may include a conference pass-through mode and a management pass-through mode, and the state information may include a conference state and a management state. The conference transparent transmission mode can send data to the second terminal only when the first terminal is in a conference state; and the first terminal can send data to the second terminal at any time in the management transparent transmission mode, if the first terminal is not in a conference state or in the conference state.
In a specific implementation, the first terminal may initiate a conference invitation and establish a conference pass-through with a plurality of second terminals located in the video network, so that when the conference scheduling server detects that the data transmission type is the conference pass-through mode and the first terminal is in a conference state, the service data may be transmitted to at least one second terminal according to the terminal information list. And when the conference scheduling server detects that the data transmission type is in a management transparent transmission mode, the server transmits the service data to at least one second terminal according to the terminal information list.
In one example, as shown in table 2:

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:
