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 video networking and the problems of the prior art, the invention provides one of the core concepts of the embodiment of the invention, namely a method for recording and broadcasting a source conference, which follows the protocol of video networking, a main user terminal establishes a conference instance terminal of the video networking conference through a conference management server, and applies the conference management server to access a recording and broadcasting server in the opened conference instance terminal to record and broadcast the live video networking conference; the conference management server sends a recording and broadcasting conference entering request aiming at the conference instance terminal to a recording and broadcasting server corresponding to the recording and broadcasting identification through a video networking server; the recording and broadcasting server selects an idle recording and broadcasting virtual terminal as a recording and broadcasting source for recording multimedia data according to the received recording and broadcasting conference entering request, and returns the recording and broadcasting virtual terminal number of the recording and broadcasting virtual terminal to the conference management server; and then the conference management server takes the recorded broadcast virtual terminal corresponding to the recorded broadcast virtual terminal number as a recorded broadcast source of the conference instance terminal to enter the conference. Compared with the prior art, the embodiment of the invention can simply and quickly access one recorded broadcast source in the established video conference of the video network, and has more flexibility.

Example 1:

as shown in fig. 5, a flowchart illustrating steps of a method for recording and broadcasting a source conference according to an embodiment of the present invention is shown, where the method may be applied to a video network, where the video network includes a recording and broadcasting server, a conference management server communicatively connected to the recording and broadcasting server through the video network server, and a main user terminal communicatively connected to the conference management server; the method may specifically comprise the steps of:

step 501, the conference management server creates a conference instance terminal according to a conference starting request sent by the main user terminal; the conference starting request is generated by the main user terminal when receiving a triggering operation of conference starting;

step 502, the conference management server receives a recording and broadcasting conference-entering request aiming at the conference instance terminal, which is sent by the main user terminal; the recording and broadcasting conference request comprises a recording and broadcasting identification of a recording and broadcasting server selected by the main user terminal;

step 503, the conference management server sends the recording and broadcasting conference entering request to a recording and broadcasting server corresponding to the recording and broadcasting identifier through a video network server; the recording and broadcasting server is used for selecting an idle recording and broadcasting virtual terminal aiming at the received recording and broadcasting conference entering request and sending the number of the selected recording and broadcasting virtual terminal to the conference management server through the video network server;

step 504, the conference management server uses the recorded broadcast virtual terminal corresponding to the recorded broadcast virtual terminal number as a recorded broadcast source of the conference instance terminal to enter the conference.

The conference management server is a management system for uniformly managing conference services, and is provided with an internet Service Web Service interface, and the Web Service is an application program which can enable different applications running on different machines to mutually exchange data or integrate without additional and special third-party software or hardware. Applications implemented according to the Web Service specification may exchange data with each other regardless of the language, platform, or internal protocol used by them. The conference management server can communicate with different main user terminals and auxiliary user terminals through a Web Service interface.

The main user terminal can be a mobile phone application program APP or a PC client or a webpage client, and a user can log in the conference management server after the user terminal operates, and a conference operation interface is displayed.

The recording and broadcasting server is an ultra-high speed storage service system supporting video recording and video on demand of a video network, is provided with a plurality of recording and broadcasting virtual terminals, and can be used for external live broadcasting, storage, later edition and video on demand. The recording and broadcasting virtual terminal can integrate and synchronously record video, audio and image signals (including computers, video exhibition stands and the like) of electronic equipment shot and recorded on the scene of the video networking conference, generate a standardized streaming media file and send the file to the recording and broadcasting server for storage.

In the embodiment of the present invention, a specific step for realizing conference entry of recording and playing equipment from the perspective of a conference management server is provided: and the conference operator selects a functional module for starting the conference in the conference operation interface of the main user terminal, and the main user terminal automatically generates a conference starting request aiming at the triggering operation. The conference management server firstly receives a conference starting request for establishing a video networking conference sent by a main user terminal, and establishes a conference instance terminal corresponding to the video networking conference in the server of the conference management server aiming at the conference starting request; the conference instance terminal is similar to a virtual background module of an actual video networking conference, and manages processes of multimedia data and the like of communication or playing of the conference.

When a conference operator wants to record and play multimedia data of the video networking conference, a recording and playing list function is selected in a conference operation interface of a main user terminal, and a recording and playing server is applied to record and play the live video networking conference. After a conference operator selects a recording and broadcasting server in a recording and broadcasting list, a main user terminal automatically generates a recording and broadcasting conference entering request of the recording and broadcasting server accessing the conference instance terminal according to the selection operation, and the recording and broadcasting conference entering request is a protocol signaling based on video networking, such as a 8f85 protocol signaling of the video networking, namely the 8f85 protocol signaling is sent to the recording and broadcasting server, and is equal to the recording and broadcasting conference entering request in the video networking. Because there are multiple recorded broadcast servers in the video network, each recorded broadcast server has its own recorded broadcast identification, namely recorded broadcast ID, and the recorded broadcast identification can be used to find the recorded broadcast server.

And the conference management server sends the recorded broadcast conference entering request to a recorded broadcast server corresponding to the recorded broadcast identification through the video networking server, and the recorded broadcast server selects an idle recorded broadcast virtual terminal as a recorded broadcast source for recording multimedia data according to the received recorded broadcast conference entering request and returns the recorded broadcast virtual terminal number of the recorded broadcast virtual terminal to the conference management server.

The recorded broadcast virtual terminal is selected according to the recorded broadcast conference request aiming at the conference instance terminal, so the recorded broadcast virtual terminal number also comprises the identification of the conference instance terminal, thus after receiving the recorded broadcast virtual terminal number, the conference management server finds the corresponding conference instance terminal according to the identification of the conference instance terminal to be conferred in the recorded broadcast virtual terminal number, and then takes the recorded broadcast virtual terminal corresponding to the recorded broadcast virtual terminal number as the recorded broadcast source of the conference instance terminal.
