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 above characteristics of the video network, one of the core concepts of the embodiments of the present invention is proposed, which follows the protocol of the video network, in the present application, when a user needs to open a video network conference between a calling video network terminal and a called video network terminal, if the calling video network terminal is not directly controlled on the calling video network terminal to establish a communication connection based on the video network protocol with the called video network terminal, the communication connection based on the video network protocol between the calling video network terminal and the called video network terminal can be remotely controlled by the video network conference management server and the video network server through the internet terminal, so that when the user is far away from the calling video network terminal, the communication connection based on the video network protocol with the called video network terminal can be established, and further, a video networking conference is started between the calling video networking terminal and the called video networking terminal.

Referring to fig. 5, there is shown a block diagram of an embodiment of the communication connection establishment system based on the internet of vision, the system includes: the system comprises aninternet terminal 01, a video networkingconference management server 02, avideo networking server 03, a callingvideo networking terminal 04, a calledvideo networking terminal 05 and a videonetworking bridge server 06, wherein the callingvideo networking terminal 04 and the calledvideo networking terminal 06 are respectively positioned in different video networks; theinternet terminal 01 and the video networkingconference management server 02 are in communication connection based on an internet protocol, the video networkingconference management server 02 and thevideo networking server 03 are in communication connection based on the video networking protocol, and thevideo networking server 03 and the callingvideo networking terminal 04 are in communication connection based on the video networking protocol; the callingvideo network terminal 04 and the videonetwork bridge server 05 are connected through a first communication based on a video network protocol, and the calledvideo network terminal 06 and the videonetwork bridge server 05 are connected through a second communication based on the video network protocol.

However, the first communication connection and the second communication connection are not associated together, so that the calling video networking terminal and the called video networking terminal do not have communication connection based on a video networking protocol, and a video networking video conference cannot be started between the calling video networking terminal and the called video networking terminal.

In order to enable a video conference between a calling video networking terminal and a called video networking terminal to be started, a communication connection based on a video networking protocol between the calling video networking terminal and the called video networking terminal needs to be established, wherein the communication connection based on the video networking protocol between the calling video networking terminal and the called video networking terminal can be established by associating a first communication connection with a second communication connection.

Therefore, referring to fig. 6, a flowchart illustrating steps of an embodiment of a method for establishing a communication connection based on a video network according to the present invention is shown, where the method may be applied to the system shown in fig. 5, and the method may specifically include the following steps:

in step S101, an internet terminal acquires a terminal identifier of a calling video networking terminal and a terminal identifier of a called video networking terminal, generates a first communication connection establishment request based on an internet protocol, where the first communication connection establishment request carries the terminal identifier of the calling video networking terminal and the terminal identifier of the called video networking terminal, and is used to request establishment of a video networking protocol-based communication connection between the calling video networking terminal and the called video networking terminal, and sends the first communication connection establishment request to a video networking conference management server;

under the general condition, a user needs to input a terminal identifier of a calling video networking terminal and a terminal identifier of a called video networking terminal in an internet terminal, however, the terminal identifiers often include a plurality of characters, and therefore, continuously inputting the terminal identifier of the calling video networking terminal and the terminal identifier of the called video networking terminal in the internet terminal can lead to more complicated user operation, and further can reduce user experience.

Therefore, in order to simplify the user operation and further improve the user experience, in another embodiment of the application, the internet terminal displays the terminal identifications of the multiple video network terminals located in the multiple video networks; the user can appoint the terminal mark of the calling video network terminal and the terminal mark of the called video network terminal in the terminal marks of the plurality of video network terminals, and the internet terminal receives the terminal mark of the calling video network terminal and the terminal mark of the called video network terminal appointed by the terminal marks of the plurality of video network terminals.

For example, the internet terminal receives a first terminal identifier specified by the terminal identifiers of the plurality of video network terminals as the terminal identifier of the calling video network terminal, and then receives a second terminal identifier specified by the terminal identifiers of the plurality of video network terminals as the terminal identifier of the called video network terminal. Therefore, the user does not need to input the terminal identification of the calling video network terminal and the terminal identification of the called video network terminal in the internet terminal, so that the user operation can be simplified, and the user experience is improved.

In the application, the internet terminal can interact with the video networking conference management server through the web service.

In step S102, the video networking conference management server receives the first communication connection establishment request, converts the first communication connection establishment request into a second communication connection establishment request based on a video networking protocol, and sends the second communication connection establishment request to the video networking server;

in step S103, the video networking server receives the second communication connection establishment request, extracts the terminal identifier of the calling video networking terminal from the second communication connection establishment request, and sends the second communication connection establishment request to the calling video networking terminal according to the terminal identifier of the calling video networking terminal;

in step S104, the calling video network terminal receives the second communication connection establishment request, and forwards the second communication connection establishment request to the video network bridging server;

in step S105, the video networking bridge server receives the second communication connection establishment request, extracts the terminal identifier of the called video networking terminal from the second communication connection establishment request, and sends the second communication connection establishment request to the called video networking terminal according to the terminal identifier of the called video networking terminal;

in step S106, the called video network terminal receives the second communication connection establishment request, generates a first communication connection establishment response based on the video network protocol, where the first communication connection establishment response is used to indicate agreement to establish a communication connection between the calling video network terminal and the called video network terminal, and sends the communication connection establishment response to the video network bridge server;

in step S107, the video networking bridge server receives the first communication connection establishment response, and associates a communication connection with the second communication connection, so as to establish a video networking protocol-based communication connection between the calling video networking terminal and the called video networking terminal.

In the application, the calling video network terminal and the called video network terminal are positioned in different video networks, when a user needs to enable the video networking conference between the calling video networking terminal and the called video networking terminal, if the calling video networking terminal is not directly controlled on the calling video networking terminal to establish the communication connection based on the video networking protocol with the called video networking terminal, the communication connection can be established through the internet terminal, establishing a communication connection between the calling video networking terminal and the called video networking terminal based on the video networking protocol at the remote control calling video networking terminal through the video networking conference management server and the video networking server, and thus, when the user is far away from the calling video network terminal, the communication connection based on the video network protocol between the user and the called video network terminal can be established, and the video network conference is started between the calling video network terminal and the called video network terminal.

Further, in order to notify the user using the internet terminal that the called video network terminal agrees to establish the communication connection between the calling video network terminal and the called video network terminal, in another embodiment of the present application, the video network bridge server may send a first communication connection establishment response to the calling video network terminal; the calling video networking terminal receives the first communication connection establishment response and sends the first communication connection establishment response to the video networking server; the video networking server receives the first communication connection establishment response and sends the first communication connection establishment response to the video networking conference management server; the video networking conference management server receives the first communication connection establishment response, converts the first communication connection establishment response into a second communication connection establishment response based on an internet protocol, and sends the second communication connection establishment response to the internet terminal; and the Internet terminal receives the second communication connection establishment response, displays the second communication connection establishment response, and the user can know that the called video networking terminal agrees to establish the communication connection between the calling video networking terminal and the called video networking terminal through the displayed second communication connection establishment response.

However, sometimes, the network fluctuates, and the video networking bridge server may not receive the second communication connection establishment request sent by the calling video networking terminal, and thus cannot establish the communication connection based on the video networking protocol between the calling video networking terminal and the called video networking terminal.

The user can wait all the time, or think that the called video network terminal does not agree to establish the communication connection between the calling video network terminal and the called video network terminal and influence the establishment of the communication connection based on the video network protocol between the calling video network terminal and the called video network terminal.

Therefore, in order to avoid the above situation, within a preset time period after the calling video networking terminal sends the second communication connection establishment request to the video networking bridge server, if the calling video networking terminal does not receive the first communication connection establishment response, first indication information based on the video networking protocol is generated, and the first indication information is used for indicating that the establishment of the communication connection based on the video networking protocol between the calling video networking terminal and the called video networking terminal is overtime and sending the first indication information to the video networking server; the video networking server receives the first indication information and sends the first indication information to the video networking conference management server; the video networking conference management server receives the first indication information, converts the first indication information into second indication information based on an internet protocol, and sends the second indication information to the internet terminal; and the Internet terminal receives the second indication information and displays the second indication information. The user can know that the establishment of the communication connection based on the video networking protocol between the calling video networking terminal and the called video networking terminal is overtime through the displayed second communication connection establishment response, and can control the internet terminal again to request the establishment of the communication connection based on the video networking protocol between the calling video networking terminal and the called video networking terminal through the process. Therefore, the situation that the user waits all the time can be avoided, and the situation that the user thinks that the called video network terminal does not agree to establish the communication connection between the calling video network terminal and the called video network terminal is avoided, so that the situation that the establishment of the communication connection between the calling video network terminal and the called video network terminal based on the video network protocol is influenced can be avoided.
