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 conference control equipment sets the information of the participants following the protocol of the video network, and when the participants are switched to speak, the related information of the participants is sent to other participants to be displayed.

Referring to fig. 5, a flowchart illustrating steps of a method for displaying participant information according to an embodiment of the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:

step 501, the conference control device sets a plurality of participant information for the plurality of video network terminals.

As shown in fig. 6, in the video network 610, the conferencing control device 611 is connected to a video network server 612, and the video network server 612 is connected to a plurality of video network terminals 613 to perform a video conference.

In a particular implementation, the video conference may be a bundle of multiple live broadcasts.

For live interactive processes, there are generally the following ways:

1. initiating live broadcast

Live broadcast data is also broadcast data

The method comprises the steps that a live video network terminal (set top box) sends an application command, a video network server automatically distributes a path of broadcast data after receiving the application, sends a coding and decoding command to the video network terminal (set top box), and simultaneously commands an upper-layer switch of the live video network terminal (set top box) to open a path of the broadcast data. The live video network terminal (set-top box) can watch the broadcast initiated by the live video network terminal, and the initiator is also a watching party.

2. Watching live broadcast

The watching video network terminal (set-top box) sends an application command, and the command comprises the number of the live broadcasting initiating party. After receiving the application, the video network server inquires whether the video network terminal (set-top box) initiating the live broadcast is connected to the network or not and whether the live broadcast is initiated or not. If the condition is not satisfied, informing the watching terminal (set top box) of the watching video network that the watching is failed.

If the conditions are met, the video network server needs to find a path between a video network terminal (set top box) initiating the live broadcast and a video network terminal (set top box) watching, a path of all switches between the live video network terminal (set top box) and the video network terminal (set top box) watching for the broadcast data is opened, and simultaneously a decoding command is sent to the video network terminal (set top box) watching, so that the video network terminal (set top box) watching can watch the live broadcast.

Each video network terminal corresponds to one participant, and one participant has participant information.

In the embodiment of the present invention, before the video conference starts, a plurality of pieces of participant information corresponding to a plurality of video networking terminals may be stored in a conference control device (Pamir client) in advance.

In one embodiment of the present invention, step 501 may include the following sub-steps:

substep S11, querying a plurality of video network numbers of the plurality of video network terminals.

And a substep S12, setting the plurality of video network numbers as keys and the plurality of participant information corresponding to the plurality of video network terminals as values, and storing the values as key value pairs in a database.

In the embodiment of the invention, the video networking number can be a unique identifier of the video networking terminal in the video networking.

The method comprises the steps of taking the video networking number of a participant (namely, a video networking terminal) as a key (key), taking the participant information of the participant (namely, the video networking terminal) as a value (value), generating a key value pair (key/value), and storing the key value pair in a database.

In particular implementations, the participant information may include one or more of:

position information, name information and remark information.

Step 502, the conference control device sends a switching instruction to the video networking server to notify the video networking server to switch a target video networking terminal of the plurality of video networking terminals to a speaking party of the video conference.

If a certain participant needs to be switched to serve as a speaking party, assuming that the video networking terminal to which the participant belongs is a target video networking terminal, the conference control device may send a switching instruction to the video networking server to notify the video networking server to switch the target video networking terminal in the plurality of video networking terminals to the speaking party of the video conference.

In specific implementation, the conference control device may send a switching instruction to the video networking server to notify the video networking server to send the audio and video data of the target video networking terminal in the plurality of video networking terminals to the plurality of video networking terminals for playing.

It should be noted that the audio and video data of the target video networking terminal may be two data streams, that is, an audio data stream and a video data stream, and are simultaneously sent to the video networking terminals participating in the video conference, where the video networking terminals may include the target video networking terminal itself.

In one embodiment of the present invention, as shown in fig. 6, in the internet 620, a centralized terminal 621 is deployed.

In the embodiment of the invention, the conference control equipment receives the switching request of the conference control terminal after protocol conversion so as to determine that a target video network terminal in a plurality of video network terminals is switched to a speaking party of the video conference.

Further, a user to which the conference control terminal (e.g., a personal computer, a tablet computer, etc.) belongs may participate in the video conference, and according to the actual situation of the video conference, when a speaking party needs to be switched, a switching request is sent to the conference control device to request a certain video networking terminal to be switched to the speaking party of the video conference.

Because the conference control terminal and the conference control equipment belong to different networks, the conference control terminal is usually accessed to the video network gateway, the conference control terminal sends the switching request to the video network gateway, and the video network gateway performs protocol conversion from the internet to the video network on the switching request and sends the switching request to the conference control equipment.

Step 503, the conference control device sends the participant information corresponding to the target video network terminal to the video network server, so as to forward the participant information to the plurality of video network terminals for display according to the downlink communication links configured for the plurality of video network terminals.

In a specific implementation, the conference control device may send pre-stored participant information corresponding to the target video network terminal to the video network server.

The video network server can issue the information of the participants according to the downlink communication links configured for a plurality of video network terminals.

And when receiving the information of the participant, the multiple video network terminals display the information on the screen.

In this practical application, the video network is a network with a centralized control function, and includes a main control 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 for a downlink communication link of a current service by notifying a switching device by the main control server, and then a data 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 the data packet of the current service sent by the source terminal to a target terminal (such as a video network terminal) 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;

further, transmitting according to the downlink communication link includes: the configured table is consulted, and the switching equipment transmits the received data packet through the corresponding port.

In particular implementations, the services include unicast communication services and multicast communication services. Namely, whether multicast communication or unicast communication, the core concept of the table matching-table can be adopted to realize communication in the video network.

As described above, the video network includes an access network portion, in which the master server is a node server, and the lower-level network device includes an access switch and a terminal.

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:

and a substep S21, the main control server obtains the downlink communication link information of the current service according to the service request protocol packet initiated by the source terminal, wherein the downlink communication link information includes the downlink communication port information of the main control server and the access switch participating in the current service.

In the substep S22, 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 S23, 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 a multicast communication service (e.g., video conference) in the access network, the step of the master server obtaining downlink information of the current service may include the following sub-steps:

in the substep S31, the main control server obtains a service request protocol packet initiated by the target terminal and applying for the multicast communication service, 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 includes a service number.
