The unified video platform adopts a menu type configuration 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.

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 or directly connected with the node server.

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

The disk array module 204 mainly implements control over the hard disk, including initialization, read-write, and other operations on the hard disk; the CPU module 203 is mainly responsible for protocol processing with an access switch and a terminal (not shown in the figure), configuring an address table 205 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 204.

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 application: 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.

Because the data flow of the video network is large, the network bandwidth resource is precious, particularly, the video network number is limited, and the transmission of the video stream in the video network needs to depend on one video network number so as to be identified by the video network, thereby ensuring the normal transmission of the video stream. At present, when an administrator of the protocol conversion server receives an instruction that a user stops receiving a video stream or an off-line instruction of the user, the protocol conversion server is disconnected in a manual operation mode, so that a video networking number is released, but the manual operation mode is not timely, sometimes the user is online but cannot normally receive the video stream, the administrator cannot find the video streaming in time, and the protocol conversion server is still in a state of sending the video stream to the user, so that the video networking number bound with the video stream is always in an occupied state, video networking resources are wasted, execution efficiency is affected, the video networking resources cannot be effectively and timely recovered, an operation memory of the protocol conversion server is occupied, and the operation speed of the protocol conversion server is affected.

Based on the characteristics of the video network and the technical problems of the present application, one of the core concepts of the embodiments of the present application is provided, in which a coordination server is in communication connection with a monitoring back-end server managing a plurality of monitoring clients according to a protocol of the video network, and the coordination server generates a heartbeat monitoring request for the monitoring clients and sends the heartbeat monitoring request to the monitoring back-end server when acquiring a first monitoring code stream of monitoring equipment corresponding to a monitoring retrieval request according to the received monitoring retrieval request; the monitoring back-end server establishes heartbeat information aiming at the monitoring client side which receives the first monitoring code stream according to the heartbeat monitoring request, sends the heartbeat information to the coordination and conversion server according to a preset time interval, and the coordination and conversion server receives the heartbeat information and replies the heartbeat information so as to establish the operation state monitoring of the monitoring client side; when the protocol conversion server does not receive the heartbeat information within the preset time interval, judging that a monitoring code stream receiving link of the monitoring client is necrotic, immediately stopping sending a second monitoring code stream, and unbinding the video networking number in the second monitoring code stream so as to release the occupation of the video networking number. Through the above mode, the embodiment of the application can effectively monitor the video networking number resource, timely process the necrotic link and recycle the video networking number resource and the bandwidth resource, realize the automatic operation of releasing the video networking number, monitor in real time, and is convenient and fast.

The monitoring sharing server 022, also known as a sharing platform, may also be understood as a gateway, and is a device that may be responsible for converting a video code stream of the monitoring device 04 in the video networking into a video code stream of a real-time transport protocol RTP protocol load, and may be used to share the video in the video networking to the monitoring platform based on RTP protocol transport.

The monitoring and scheduling server 021 may be a backend platform of a video networking monitoring and networking management and scheduling platform, and is responsible for unified management of all accessed monitoring clients 03 in the video networking, and specifically may communicate with the monitoring clients 03 through a streaming media gateway, and communicate with the monitoring and sharing server 022 through the video networking.

The monitoring client 03 mentioned in the embodiment of the present application may be a monitoring client (commonly referred to as an application APP), which may be installed on hardware such as a mobile phone, a tablet, a desktop, and a notebook, and belongs to the front end of the video networking monitoring and networking management and scheduling platform, and is responsible for displaying an overall monitoring directory, retrieving a monitoring video, and configuring various functions of the video networking monitoring and networking management and scheduling platform.

Example 2:

as shown in fig. 6, a flowchart illustrating steps of a method for monitoring a number resource of a video network according to an embodiment of the present application is shown, where the method may be applied to a video network, and specifically may be applied to a coordination server 01 shown in fig. 5, and the method may specifically include the following steps:

step S601: the cooperative conversion server receives a monitoring calling request forwarded by the monitoring back-end server; the monitoring calling request is generated by a monitoring client when a triggering operation of monitoring calling is received;

the monitoring client 03 in the embodiment of the present application may have a plurality of display interfaces, such as a monitoring scheduling interface and a monitoring query interface.

The triggering operation of monitoring and invoking mentioned in the embodiment of the present application may be that a user clicks a viewing button in a monitoring and scheduling interface with a mouse, or address information of a monitoring camera input by the user in the monitoring and scheduling interface or the monitoring and querying interface, or monitoring resource input information or viewing button of a certain area selected by the user in the monitoring and scheduling interface or the monitoring and querying interface, and the triggering operation for the purpose of the embodiment of the present application may be implemented, which is not described herein in detail.

The monitoring client 03 generates a monitoring calling request corresponding to the monitoring according to the received trigger operation, that is, the monitoring calling request may be a request for calling monitoring data acquired by one camera, or may be a request for calling monitoring data acquired by a plurality of designated monitoring cameras, or a request for calling monitoring data acquired by monitoring cameras in a certain area.

Then, the monitoring client 03 sends the monitoring invoking request to the monitoring back-end server 02, and the steps of receiving the monitoring invoking request sent by the monitoring client 03 by the monitoring back-end server 02 and sending the monitoring invoking request to the coordination server 01 include:

the monitoring scheduling server 021 receives a monitoring invoking request sent by the monitoring client 03, and sends the monitoring invoking request to the monitoring sharing server 022;

the monitoring sharing server 022 receives the monitoring invoking request and sends the monitoring invoking request to the coordination server 01.

Step S602: the coordination conversion server acquires a first monitoring code stream of the monitoring equipment corresponding to the monitoring calling request according to the monitoring calling request, and generates a heartbeat monitoring request aiming at the monitoring client;

in the embodiment of the present application, steps of obtaining a first monitoring code stream and generating a heartbeat monitoring request for the monitoring client after the coordination server 01 receives the monitoring invoking request are shown.

In the above steps, the monitoring invoking request includes an IP address of the monitoring device 04 that is to be invoked, and a communication address and an identification identifier of the monitoring client that is to invoke the monitoring code stream; therefore, the cooperative conversion server 01 can find the corresponding monitoring device 04 according to the IP address, and then performs service protocol communication with the monitoring device 04 to obtain the first monitoring code stream of the monitoring device 04.

After receiving the first monitoring code stream, the corotation server 01 simultaneously uses the received first monitoring code stream as a trigger signal to generate a heartbeat monitoring request for the monitoring client 03; that is, the heartbeat monitoring request includes the communication address and the identification of the monitoring client 03.

Step S603: the protocol conversion server generates a second monitoring code stream aiming at the acquired first monitoring code stream; the second monitoring code stream comprises a video networking number bound with the first monitoring code stream;

in the embodiment of the application, the protocol conversion server 01 further stores a plurality of video networking numbers, the number of the video networking numbers is set based on certain user requirements, and like the existing fixed telephone or mobile phone numbers, the number digits and codes are limited, so that the number of the video networking numbers is limited.

In a preferred embodiment of the present application, it is shown that the step of generating, by the coordination server 01, a second monitoring code stream for the obtained first monitoring code stream specifically may include:

the protocol conversion server 01 queries a video networking number which is stored in the protocol conversion server and is in an idle state aiming at the acquired first monitoring code stream;

and the protocol conversion server 01 selects an idle video networking number to be bound with the first monitoring code stream to generate a second monitoring code stream.

The video code stream is transmitted in sequence in the form of a plurality of data packets, one data packet comprises a header and a body, and the body has data content; therefore, the binding mode can adopt a mode of writing in the data packet header of the first monitoring code stream.

The binding mode may also be an identifier linking mode, that is, a plurality of video networking numbers are stored in a table mode in a video networking protocol of the protocol conversion server 01, the table has a unique number or identifier representing the video networking number, the protocol conversion server also establishes a data transmission channel for the monitoring code stream in the process of transmitting the monitoring code stream, and then the identifier or the number of one unique video networking number may be linked to the data transmission channel of the monitoring code stream.

Step S604: the coordination server sends the second monitoring code stream and the heartbeat monitoring request to the monitoring back-end server; the monitoring back-end server is used for sending the second monitoring code stream to the monitoring client; the monitoring client is used for displaying the second monitoring code stream;

for the above steps, since the monitoring backend server 02 may include the monitoring scheduling server 021 and the monitoring sharing server 022 that are communicatively connected to each other, specifically, the above steps may specifically include:

the monitoring shared server 022 receives a second monitoring code stream sent by the co-rotation server 01, and sends the second monitoring code stream to the monitoring scheduling server 021;

and the monitoring scheduling server 021 receives the second monitoring code stream, and sends the second monitoring code stream to the monitoring client 03.

Step S605: the cooperative conversion server receives heartbeat information sent by the monitoring back-end server according to a preset time interval; wherein the heartbeat information is generated by the monitoring backend server for the heartbeat monitoring request;

after receiving the heartbeat monitoring request, the monitoring back-end server 02 may establish a heartbeat monitoring thread for the monitoring client 03 in the monitoring shared server 022, then continuously obtain the running state of the monitoring client 03 located in the monitoring scheduling server 021, generate heartbeat information, and send the heartbeat information to the coordination server 01.

Or, a heartbeat monitoring thread for the monitoring client 03 may be established in the monitoring scheduling server 021, and the monitoring scheduling server 021 directly responds to the corotation server 01 through the monitoring sharing server 022 to the state where the monitoring client 03 receives the second monitoring code stream, that is, reflects whether normal reception is possible.

Step S606: and when the heartbeat information is not received within the preset time interval, the coordination server stops sending a second monitoring code stream and unbinds the video networking number in the second monitoring code stream.

The embodiment of the application shows that the corotation server 01 can also establish a response in the interior according to the received heartbeat information, the mechanism can judge whether the heartbeat information can be normally received, when the heartbeat information exceeds the preset time, the link necrosis of the data transmission channel is judged, the video networking number and the first monitoring code stream are unbound, the occupation of the video networking number is removed, the necrotic link is timely processed, the video networking number resource and the bandwidth resource are recovered, the automatic operation of removing the video networking number is realized, the real-time monitoring is realized, and the convenience and the rapidness are realized.

In addition, for the above response mechanism, in a preferred embodiment of the present application, the method for the collaboration server 01 to respond to the heartbeat information may further include the following steps:

Thus, the monitoring backend server 02 may also determine whether the cooperative server 01 is normal or not according to the heartbeat feedback signal.

Example 3:

as shown in fig. 7, a flowchart illustrating steps of another method for monitoring a number resource of a video network according to an embodiment of the present application is shown, where the method may be applied to a video network, and in particular, may be applied to the monitoring backend server 02 shown in fig. 5, and the method may specifically include the following steps:

step S701: the monitoring back-end server receives a monitoring calling request sent by the monitoring client; the monitoring calling request is generated by a monitoring client when a triggering operation of monitoring calling is received;

step S702: the monitoring back-end server sends the monitoring calling request to the coordination transfer server; the coordination conversion server is used for acquiring a first monitoring code stream of the monitoring equipment corresponding to the monitoring calling request according to the monitoring calling request and generating a heartbeat monitoring request aiming at the monitoring client;

step S703: the monitoring back-end server receives a second monitoring code stream and the heartbeat monitoring request sent by the protocol conversion server; the second monitoring code stream is generated by binding the first monitoring code stream with a video networking number aiming at the acquired first monitoring code stream by the coordination server;

step S704: the monitoring back-end server sends the second monitoring code stream to the monitoring client; the monitoring client is used for displaying the second monitoring code stream;

step S705: the monitoring back-end server generates heartbeat information aiming at the monitoring client according to the heartbeat monitoring request;

step S706: the monitoring back-end server sends the heartbeat information to the corotation server according to a preset time interval; the protocol conversion server is used for stopping sending a second monitoring code stream and unbinding a video network number in the second monitoring code stream when the heartbeat information is not received;

step S707: when a second monitoring code stream sent by the protocol conversion server is not received, the monitoring back-end server generates monitoring code stream stop data and sends the monitoring code stream stop data to the monitoring client; and the monitoring client is used for stopping displaying the monitoring code stream.
