Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic diagram of an implementation environment according to an embodiment of the present application. In fig. 1, a plurality of virtual terminals are connected to the video network server, and when the virtual terminals communicate with each other, the virtual terminals need to be connected in a communication manner through the video network server. The virtual terminal may also be understood as a video network system, in which a terminal device or a server may serve as the video network system, and for the convenience of statement of various embodiments of the present application, the server here is different from the video network server shown in fig. 1.

In the related art, in order to avoid the complicated step of frequently establishing a channel connection between two virtual terminals, a long connection between the two virtual terminals may be established by using a videophone protocol, for example, when the virtual terminal 1 needs to communicate with the virtual terminal 2, the two parties may establish the long connection by using the videophone protocol and through a networking server. However, when the two parties are in the connected state, the other virtual terminals under the video network server cannot establish communication connection with any one of the virtual terminal 1 or the virtual terminal 2 again, that is: only by waiting for the connection between the virtual terminal 1 and the virtual terminal 2 to be released, a communication connection can be established with the virtual terminal 1 or the virtual terminal 2, which causes the virtual terminal number resource to be occupied for a long time. Therefore, in a scene with high concurrent requests, when the virtual terminal 1 needs to perform service interaction with a plurality of other virtual terminals, the existing videophone protocol cannot fully utilize the number resources of the virtual terminals, and needs to be improved in terms of improving the response speed of a video networking system.

In order to overcome the problems, the application provides a technical concept for establishing the analog long connection between the virtual terminals, which can avoid the complex steps of frequently establishing channel connection between the two virtual terminals, fully utilize the number resources of the virtual terminals and improve the response speed of the video networking system.

Based on the technical concept, the application provides a method for establishing a video networking communication connection, which is applied to the virtual terminal in fig. 1. Fig. 2 is a flow chart illustrating a method for establishing a video networking communication connection according to an embodiment of the present application. Referring to fig. 2, the method for establishing a video networking communication connection of the present application may include the steps of:

step S11: and determining a target virtual terminal to be established with long connection of the video network, wherein the source virtual terminal and the target virtual terminal are both registered under the same video network server.

In this embodiment, two virtual terminals registered under the same video network server can establish a long video network connection. The source virtual terminal can be any virtual terminal under the video network server. The execution subject of the method for establishing the video networking communication connection in the embodiment of the application is the source virtual terminal.

In step S11, referring to fig. 1, when the virtual terminal 1 needs to establish a long video network connection with the virtual terminal 2, the source virtual terminal is the virtual terminal 1, and the target virtual terminal is the virtual terminal 2.

Step S12: and generating a communication connection request aiming at the target virtual terminal.

After the source virtual terminal determines the target virtual terminal, a communication connection request for requesting to establish a long connection of the video network with the target virtual terminal may be generated for the target virtual terminal.

Step S13: and sending the communication connection request to the target virtual terminal.

After the source virtual terminal generates the communication connection request, the communication connection request can be sent to the target virtual terminal through the video networking server.

Step S14: and receiving a response returned by the target virtual terminal.

In this embodiment, after receiving a communication connection request sent by a source virtual terminal, a target virtual terminal may agree to establish a communication connection or refuse to establish a communication connection, and when agreeing to establish a communication connection, a response indicating that it agrees to establish a communication connection with the source virtual terminal is generated and returned to the source virtual terminal through a video network server; and when the communication connection is refused to be established, generating a response which represents that the communication connection with the source virtual terminal is refused to be established, and returning the response to the source virtual terminal through the video network server.

Step S15: and when the response indicates that the target virtual terminal agrees to establish the communication connection with the source virtual terminal, determining that the long connection of the video network with the target virtual terminal is established successfully.

In this embodiment, if the received response indicates that the target virtual terminal agrees to establish the communication connection with the source virtual terminal, the source virtual terminal may determine that the long video network connection with the target virtual terminal is successfully established, and then may perform data transmission with the target virtual terminal.

Step S16: and determining a new virtual terminal to be established with the long connection of the video network in the connection state, wherein the new virtual terminal is any one of the virtual terminals registered under the video network server except the target virtual terminal.

Step S17: generating a communication connection request for the new virtual terminal to establish a long video network connection with the new virtual terminal.

In this embodiment, any one virtual terminal may establish long connection with a plurality of other virtual terminals under the peer-to-peer network server at the same time. Therefore, all the virtual terminals can be connected through the video network to form a mesh structure. Illustratively, the virtual terminal 1 may establish a long connection of the video network with one or more virtual terminals of the virtual terminals 2-n at the same time, thereby implementing service interaction with multiple virtual terminals at the same time in a high-concurrency request scenario.

For example, referring to fig. 1, a virtual terminal 1 may establish a long video network connection with each of virtual terminals 2-n, a virtual terminal 2 may establish a long video network connection with each of virtual terminals 3-n, a virtual terminal 3 may establish a long video network connection with each of virtual terminals 4-n, and so on, until all virtual terminals under a video network server may establish a long video network connection channel between each two virtual terminals, a mesh channel based on a video network server is formed, so that any one virtual terminal may perform bidirectional communication with multiple other virtual terminals based on the mesh channel, and mass services may be processed quickly under high concurrent requests.

In this embodiment, by the provided method for establishing the communication connection of the video network, a source virtual terminal first determines a target virtual terminal to be established with long connection of the video network, and the source virtual terminal and the target virtual terminal are both registered under the same video network server; then generating a communication connection request aiming at the target virtual terminal; then sending the communication connection request to a target virtual terminal; after receiving a response returned by the target virtual terminal, judging whether the response indicates agreement to establish communication connection, and if the response indicates agreement to establish communication connection, determining that the long connection of the video network with the target virtual terminal is established successfully; then, in the period that the long connection of the video network is in the connection state, the source virtual terminal can also establish the long connection of the video network again with any other one or more virtual terminals under the same video network server, and finally a mesh passage based on the video network server is formed. In the embodiment, by establishing the long connection mode of the video network, not only can the complicated step of frequently establishing channel connection between two frequently-interacted virtual terminals be avoided, but also any virtual terminal can simultaneously carry out communication interaction with a plurality of other virtual terminals based on the mesh passage of the video network server, so that the number resources of all virtual terminals are fully utilized, massive services can be rapidly processed under high concurrent requests, and the response speed of the system is effectively improved.

With reference to the foregoing embodiment, in an implementation manner, after the long connection between the source virtual terminal and the target virtual terminal is successfully established, the long connection between the source virtual terminal and the target virtual terminal needs to be maintained through the long connection server. Specifically, after the step S15, the source virtual terminal may further perform the following steps:

sending a message of successful communication connection to the video networking server, wherein the video networking server is used for maintaining the long video networking connection between the source virtual terminal and the target virtual terminal according to a preset connection maintenance strategy after receiving the message;

and when a heartbeat packet sent by the video network server is received, returning a response for confirming the reception of the heartbeat packet so as to inform the video network server to maintain the long video network connection, wherein the heartbeat packet is periodically sent to each video network virtual terminal for maintaining the long video network connection established by each video network virtual terminal after the video network server receives the message.

In this embodiment, it may be set in all the virtual terminals, and as long as the type of the received communication connection request is that the long connection of the video network is established and the connection is successfully established, the connection is always maintained by default without actively closing, and specifically, the operation of the program related to the long connection of the video network may not be stopped, so as to maintain the long connection.

After determining that the long video network connection between the source virtual terminal and the target virtual terminal is successfully established, the source virtual terminal sends a message that the communication connection is successful to a video network server, and the video network server correspondingly records the source virtual terminal and the target virtual terminal to indicate that the long video network connection exists between the source virtual terminal and the target virtual terminal. And meanwhile, after receiving the message, the video network server also periodically sends heartbeat packets to the source virtual terminal and the target virtual terminal, once any one of the source virtual terminal and the target virtual terminal does not return a response for confirming the reception of the heartbeat packets, the video network server determines that the long connection of the video network of the two parties is disconnected, and respectively sends the message of disconnection to the two parties.

Actually, the video network server stores a virtual terminal information table, the table records the mapping between the Mac address of each virtual terminal and the virtual terminal number, the video network server sends heartbeat packets to all the existing virtual terminals in the table in a broadcasting mode at regular time, and the virtual terminal receiving the heartbeat packets returns a response confirming the received heartbeat packets to the video network server.

When the video network server does not receive the response of confirming that the heartbeat packet is received, which is returned by the virtual terminal, after the heartbeat packet is sent by the video network server at a certain time, the video network server determines other virtual terminals which are previously in long video network connection with the virtual terminal, and respectively sends disconnection messages to the virtual terminals, so that the virtual terminals can re-request to establish long video network connection after receiving the disconnection messages.

In this embodiment, through the video network server, the maintenance of the long connection of the video network between any two virtual terminals can be realized, through the long connection of the video network, the tedious steps of frequently establishing channel connection between two frequently interactive virtual terminals can be avoided, the time of establishing channel connection is saved, and the response speed of the system is improved.

With reference to the foregoing embodiment, in an implementation manner, a target virtual terminal number corresponding to the target virtual terminal and a source virtual terminal number corresponding to the source virtual terminal are unique in virtual terminal numbers corresponding to virtual terminals of a video network registered in the video network server;

step S12 may include:

acquiring a target virtual terminal number corresponding to the target virtual terminal;

generating a communication connection request based on the target virtual terminal number, wherein the communication connection request carries a source virtual terminal number of the communication connection request;

correspondingly, the message that the communication connection is successful is sent to the video networking server, and the message comprises:

generating a message of successful communication connection based on the target virtual terminal number of the target virtual terminal and the source virtual terminal number of the target virtual terminal;

and sending the message that the communication connection is successful to the video networking server.

In this embodiment, each virtual terminal has a virtual terminal number, and the virtual terminal number can be used to uniquely identify the virtual terminal, that is: the virtual terminal numbers of all the video network virtual terminals registered under the same video network server are different.

In the video network, the service interaction between terminals or servers is carried out through virtual terminal numbers. The virtual terminal numbers are pre-allocated by a system in charge of virtual terminal number allocation before service processing, and correspond to Mac addresses one by one, and one Mac address corresponds to one virtual terminal number.

In this embodiment, when a source virtual terminal generates a communication connection request for a target virtual terminal, it needs to obtain a target virtual terminal number corresponding to the target virtual terminal, and generates the communication connection request based on the target virtual terminal number and its own source virtual terminal number, and when receiving the communication connection request, the video network server may forward the communication connection request to the corresponding target virtual terminal according to the target virtual terminal number, and after receiving a response returned by the target virtual terminal, may forward the response to the corresponding source virtual terminal according to the source virtual terminal number. Of course, the communication connection request may also carry information such as the respective MAC addresses of the source virtual terminal and the target virtual terminal, which is not specifically limited in the present application.

After the source virtual terminal determines that the long connection of the video network with the target virtual terminal is successfully established, a message of successful communication connection is generated based on the source virtual terminal number of the source virtual terminal and the target virtual terminal number of the target virtual terminal, and the message is sent to the video network server, so that the video network server correspondingly stores the source virtual terminal number and the target virtual terminal number after receiving the message, and a long connection channel of the video network exists between the source virtual terminal and the target virtual terminal.

In this embodiment, since the virtual terminals can establish a plurality of long connection channels of the video network, compared with the related art in which the long connection channels of the video network are established between two virtual terminals and occupy the virtual terminal number resource for a long time, the phenomenon that the virtual terminal number resource is occupied for a long time does not exist, the virtual terminal number resource can be fully utilized, and meanwhile, service interaction is performed with the virtual terminals, so that a high-concurrency request scene can be effectively responded, and the response speed of a request is improved.

With reference to the foregoing embodiment, in an implementation manner, after it is determined that the long video network connection with the target virtual terminal is established successfully, the source virtual terminal and the target virtual terminal may further perform data transmission through the established long video network connection channel, as shown in fig. 3.

FIG. 3 is a flow diagram illustrating a method for processing task requests according to an embodiment of the present application. Referring to fig. 3, the method for establishing a communication connection of a video network of the present application may further include the steps of:

step S21: and acquiring a task request to be processed.

In this embodiment, any one virtual terminal includes a plurality of sub-devices, and different types of task requests to be processed can be generated by different sub-devices, for example, the sub-device 1 is used to generate a video type task request, and the sub-device 2 is used to generate an audio type task request. Each sub-device has a sub-device number, and the virtual terminal distinguishes a plurality of different sub-devices according to the sub-device numbers.

Step S22: and adding task numbers to the to-be-processed task requests, wherein the task numbers corresponding to the to-be-processed task requests are different.

In this embodiment, one virtual terminal may generate many pending task requests within the same time period, in order to distinguish different pending task requests and prevent a network disorder phenomenon when obtaining a response, so that a task number may be added to the pending task request when generating the pending task request.

For example, the virtual terminal may add a task number to each to-be-processed task request that is sequentially generated according to the numbers 1-9999, and when the numbers reach 9999, add the task numbers to each to-be-processed task request again according to the order 1-9999.

Step S23: and sending the task request to be processed to the video network server, wherein the video network server is used for forwarding the task request to be processed to a corresponding virtual terminal, and the virtual terminal is used for processing the task request to be processed.

In this embodiment, after each virtual terminal generates and numbers a to-be-processed task request, the numbered to-be-processed task request may be stored in a sending queue, a sending thread reads each to-be-processed task request in the sending queue and sends the to-be-processed task request to the video network server, the video network server obtains a target virtual terminal number therein after receiving the to-be-processed task request, sends the to-be-processed task request to a target virtual terminal according to the target virtual terminal number, obtains task response data after the target virtual terminal processes the to-be-processed task request, generates a task response according to the task response data, and sends the task response to the video network server.

Step S24: and receiving a task response sent by the video network server.

Step S25: and acquiring the task number in the task response.

In this embodiment, after obtaining the task response, the virtual terminal obtains the task number carried by the virtual terminal, and after processing the task request to be processed, the target virtual terminal also carries the task number originally carried by the target virtual terminal in the task response.

Step S26: and when the task number in the task response is the same as the task number in the task request to be processed, determining that the task response is a response corresponding to the task request to be processed.

And if the task number is the same as the task number in the sent task request to be processed, the task response is the task response corresponding to the task request to be processed.

Illustratively, after the virtual terminal 1 establishes long connection with the virtual terminal 2 and the virtual terminal 3 respectively, the sub-device 1 of the virtual terminal 1 generates a task request 1 for requesting video resources, the sub-device 2 generates a task request 2 for requesting audio resources, the virtual terminal 1 adds a task number 100 to the task request 1 and adds a task number 101 to the task request 2, then the task request 1 and the task request 2 are stored in a sending queue, the sending thread reads the task request 1 and the task request 2 from the sending queue and sends the task request 1 and the task request 2 to the video network server, the video network server sends the task request 1 to the virtual terminal 2 according to a target virtual terminal number carried in the task request 1, supposing the virtual terminal number of the virtual terminal 3 according to the target virtual terminal number carried in the task request 2, sending the task request 2 to the virtual terminal 3; after the virtual terminal 2 processes the task request 1, a task response 1 is generated, a task number 100 initially carried by the virtual terminal is added, then the task response 1 is sent to the video network server, and the video network server sends the task response 1 to the virtual terminal according to the source virtual terminal number carried in the task response 1, namely: the virtual terminal number of the virtual terminal 1 sends the task response 1 to the virtual terminal 1; after the virtual terminal 3 processes the task request 2, a task response 2 is generated, meanwhile, a task number 101 carried by the virtual terminal is added, then the task response 2 is sent to the video network server, and the video network server sends the task response 2 to the virtual terminal according to the source virtual terminal number carried in the task response 2, namely: the virtual terminal number of the virtual terminal 1 sends the task response 2 to the virtual terminal 1; after receiving the task response 1, the virtual terminal 1 obtains the task number 100 carried therein, and since the task number 100 is the same as the task number 100 of the task request 1, it can be determined that the task number is a response corresponding to the task request 1, and similarly, after receiving the task response 2, the virtual terminal 1 obtains the task number 101 carried therein, and since the task number 101 is the same as the task number 101 of the task request 2, it can be determined that the task number is a response corresponding to the task request 2.

In this embodiment, when a plurality of task requests are sent to the outside, the source virtual terminal numbers each task request, so that when a task response is received, the task request to which the task response belongs can be quickly determined, network disorder can be effectively prevented (i.e., the request and the response are not matched), meanwhile, based on the setting of the task number, when a large number of task requests face, the task requests can be quickly processed, and the capability of dealing with a high-concurrency request scene is improved.

With reference to the foregoing embodiment, in an implementation manner, the sending the communication connection request to the target virtual terminal includes:

sending the communication connection request to the video networking server so that the video networking server sends the communication connection request to the target virtual terminal;

receiving a response returned by the target virtual terminal, wherein the response comprises:

and receiving a response returned by the video network server, wherein the response is sent to the video network server by the target virtual terminal.

In this embodiment, data interaction between any virtual terminals is forwarded by the video network server.

The application also provides a method for establishing the communication connection of the video network, which comprises the following steps:

when the response indicates that the target virtual terminal agrees to establish the communication connection with the source virtual terminal, the source virtual terminal determines that the long connection of the video network with the target virtual terminal is successfully established and sends a message of successful communication connection to the video network server;

during the period that the long connection of the video network is in a connection state, the source virtual terminal determines a new virtual terminal to establish the long connection of the video network, wherein the new virtual terminal is any one of the virtual terminals registered under the video network server except the target virtual terminal;

For the detailed description of the above process, reference may be made to the foregoing description, and details are not repeated herein.

With reference to the foregoing embodiment, in an implementation manner, after the source virtual terminal determines that the long connection to the video network between the source virtual terminal and the target virtual terminal has been successfully established, the method further includes:

the source virtual terminal obtains task requests to be processed, adds task numbers to the task requests to be processed, and sends the task requests to be processed after the serial numbers are added to the video network server, wherein the task numbers corresponding to the task requests to be processed are different;

the video network server determines the video network long connection corresponding to the target virtual terminal in the video network long connection established by the source virtual terminal, and sends the task request to be processed to the target virtual terminal through the video network long connection;

the video network server sends the task response to the source virtual terminal;

and the source virtual terminal obtains a task number carried in the task response, and determines that the task response is a response corresponding to the task request to be processed when the task number in the task response is the same as the task number in the task request to be processed.

Fig. 4 is a schematic diagram illustrating a method for establishing a video networking communication connection according to an embodiment of the application. The method for establishing the communication connection of the video network of the present application will be described in a specific embodiment with reference to fig. 4.

In fig. 4, the V2V system is: the video network system, such as the terminal device or the server in the video network, can be regarded as the V2V system, and V2V is the video network server (the video network server here is different from the server at the V2V system).

To enable those skilled in the art to better understand the embodiments of the present invention, the following description is given of the internet of view:

some of the techniques applied by the video network are as follows:

network Technology (Network Technology)

Network innovations in video networking have improved the traditional Ethernet (Ethernet) to face the potentially enormous video traffic on the network. Unlike pure network Packet Switching (Packet Switching) or network Circuit Switching (Circuit Switching), the video networking technology adopts Packet Switching to meet the Streaming requirement. The video networking technology has the advantages of flexibility, simplicity and low price of packet switching, and simultaneously has the quality and safety guarantee of circuit switching, and realizes the seamless connection of a whole network switching type virtual circuit and a data format.

Service Innovation Technology (Service Innovation Technology)

The unified video platform integrates services and transmission, and is not only automatically connected once, but also connected with a single user, a private network user or the sum of one network. The user terminal, the set-top box or the PC are directly connected to the unified video platform to obtain various multimedia video services in various forms. The unified video platform adopts a menu type matching table mode to replace the traditional complex application programming, can realize complex application by using very few codes, and realizes infinite new service innovation.

Networking of the video network is as follows:

the video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the network.

Fig. 7 is a schematic networking diagram of a video network according to an embodiment of the present application. As shown in fig. 7, the view network is divided into two parts, an access network and a metropolitan network.

The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.

The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server can be directly connected with the access switch or directly connected with the terminal.

Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.

The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch and can also be directly connected with the node server.

Therefore, the whole video network is a network structure controlled by a hierarchical centralized way, and the network controlled by the node server and the metropolitan area server can be in various structures such as a tree, a star, a ring and the like.

The access network part can form a unified video platform (the part in a dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform may be interconnected via metropolitan area and wide area video networking.

2. Vission networking data 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., more than 2 connections between a node switch and a node server, between a node switch and a node switch, and between a node switch and a node server. However, the 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 the present 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 there are 2 labels for the packet from the device B to the device a. The label is divided into an in label and an out label, and assuming that the label (in label) of the data packet entering the device a is 0x0000, the label (out label) of the data 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 all passively executed, which is different from label allocation of MPLS, which 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 as follows: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, which is located between the reserved bytes and the 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, a plurality of video network long connections are mutually established among a plurality of virtual terminals located under the same video network server according to a video network protocol, and by means of establishing the video network long connections, the complicated step of frequently establishing channel connections between two frequently-interacted virtual terminals can be avoided, and based on a mesh path of the video network server, any one virtual terminal can be communicated and interacted with other virtual terminals at the same time, so that the number resources of all the virtual terminals are fully played, massive services can be rapidly processed under high concurrent requests, and the response speed of the system is effectively improved.
