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 data packets, and is 64 bytes if the data packet is a variety of protocol packets, and is 32+1024 or 1056 bytes if the data packet is a unicast data 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, the monitoring and checking scheme provided by the embodiment of the invention follows the protocol of the video network, and the two monitoring access servers are responsible for monitoring and checking the process, so that the phenomenon of picture blocking is avoided, and the user experience is improved.

The monitoring and checking scheme of the embodiment of the invention can be applied to the video network. The video network monitoring and accessing system can comprise a video network monitoring and accessing management platform, a monitoring and accessing server and a video network terminal, the video network monitoring and accessing management platform and the video network terminal can interact based on a video network protocol, the video network terminal and the monitoring and accessing server can interact based on the video network protocol, and the video network monitoring and accessing management platform and the monitoring and accessing server can interact based on the video network.

The monitoring access server is an entrance for accessing the monitoring resources into the video network, and can access various types of monitoring resources and transmit video data acquired by the monitoring resources into the video network. The monitoring access server can be responsible for analyzing video data of monitoring resources, releasing live broadcast and the like. The embodiment of the invention considers that if one monitoring access server is in charge of analyzing the video data and releasing the video data, the thread for analyzing the video data may block the thread for releasing the video data, so that a user can generate a pause phenomenon when watching the video data, and the user experience is reduced. Therefore, in the embodiment of the present invention, the function of one monitoring access server is divided into two monitoring access servers, a first monitoring access server and a second monitoring access server are provided, monitoring resources accessed by the first monitoring access server and the second monitoring access server are the same, the two monitoring access servers are respectively responsible for analyzing video data and issuing video data, the two processes are independent from each other, and a pause phenomenon can be avoided.

Example one

Referring to fig. 5, a flowchart illustrating steps of a monitoring and viewing method according to a first embodiment of the present invention is shown. The method can be applied to video networking.

The monitoring and checking method of the embodiment of the invention can comprise the following steps:

Step 501, a first monitoring access server receives a monitoring detection request sent by a monitoring networking management platform, and determines a target monitoring resource according to the monitoring detection request.

the user can trigger a monitoring detection request aiming at the target monitoring resource by executing related operations on the video networking monitoring networking management platform. For example, the internet of vision monitoring management platform may provide a user interface in which a user of the internet of vision monitoring management platform may perform relevant operations to trigger the monitoring detection request.

in the embodiment of the invention, the first monitoring access server can be responsible for analyzing the video data. After the video networking monitoring networking management platform obtains the monitoring detection request, the monitoring detection request is sent to the first monitoring access server through the video networking protocol, and the first monitoring access server can determine target monitoring resources according to the monitoring detection request. For example, the monitoring detection request may include information such as an identifier of the target monitoring resource, and the first monitoring access server may determine the target monitoring resource according to the identifier.

Step 502, the first monitoring access server determines whether the video data of the target monitoring resource meets a preset alarm condition.

The first monitoring access server analyzes the video data of the target monitoring resource to judge whether the video data of the target monitoring resource meets a preset alarm condition.

for the alarm condition, a person skilled in the art can set any suitable alarm condition according to the actual alarm condition required. For example, when the people count condition needs to be warned, a warning condition can be set according to the people count in the video data, for example, the people count in the video data exceeding a set threshold can be set as the warning condition; for another example, when an alarm is needed for an emergency, an alarm condition may be set according to an emergency picture in the video data, for example, a preset picture appearing in the video data may be set as the alarm condition, where the preset picture may be a flame picture, a smoke picture, or the like.

And 503, the first monitoring access server generates alarm information after the judgment result is satisfied, and returns the alarm information to the video network monitoring and networking management platform.

And the first monitoring access server generates corresponding alarm information after judging that the video data of the target monitoring resource meets the preset alarm condition. The alarm information may include information such as an identifier of the target monitoring resource and alarm content. For example, if the alarm condition is that the number of people in the video data exceeds a set threshold, the alarm content may be the number of people in the video data; if the alarm condition is that a preset picture appears in the video data, the alarm content may be the content of the preset picture, such as flame, smoke, etc.

Step 504, the second monitoring access server receives a monitoring viewing request which is generated by the video network monitoring and network managing platform for the alarm information and is sent by the video network terminal, and determines the target monitoring resource according to the monitoring viewing request.

the first monitoring access server can return the alarm information to the video networking monitoring networking management platform based on the video networking protocol, and the video networking monitoring networking management platform can generate a monitoring viewing request aiming at the alarm information after receiving the alarm information. In the embodiment of the invention, the video network monitoring and networking management platform can automatically generate a monitoring and viewing request after receiving the alarm information; the warning information can also be displayed in a user interface, and a user of the video networking monitoring and managing platform can perform related operations in the interface to trigger the video networking monitoring and managing platform to generate a monitoring and viewing request.

The video networking monitoring and networking management platform sends the monitoring and viewing request to the second monitoring access server through the video networking terminal, namely the video networking monitoring and networking management platform sends the monitoring and viewing request to the video networking terminal on the basis of the video networking protocol, and then the video networking terminal sends the monitoring and viewing request to the second monitoring access server on the basis of the video networking protocol.

The second monitoring access server may determine the target monitoring resource according to the monitoring viewing request. For example, the monitoring and viewing request may include information such as an identifier of the target monitoring resource, and the second monitoring access server may determine the target monitoring resource according to the identifier.

And 505, the second monitoring access server issues the video data of the target monitoring resource and returns the viewing information corresponding to the video data to the video network terminal.

And after the second monitoring access server determines the target monitoring resource, the second monitoring access server issues the video data of the target monitoring resource, acquires the viewing information corresponding to the video data of the target monitoring resource, and returns the viewing information to the video network terminal based on the video network protocol. The video network terminal can obtain the video data of the target monitoring resource according to the viewing information and play the video data, and a user of the video network terminal can view the video data on the video network terminal.

the embodiment of the invention divides the function of one monitoring access server into two monitoring access servers for execution, wherein one monitoring access server is responsible for analyzing the video data, and the other monitoring access server is responsible for publishing the video data, thereby avoiding the video blocking phenomenon generated when the monitoring video is checked under the condition that one monitoring access server is responsible for analyzing and publishing, improving the user experience, and reducing the load of the monitoring access servers.

The video network monitoring client can provide a user interface, a monitoring resource list can be displayed in the user interface, and relevant information of the monitoring resource, such as identification and working state of the monitoring resource, identification of a monitoring access server for monitoring resource access and the like, is recorded in the monitoring resource list. The user interface can also provide a detection button for the monitoring resource, and a user can trigger a monitoring detection request for the target monitoring resource by clicking the detection button corresponding to the target monitoring resource. After receiving the monitoring detection request, the video networking monitoring client can send the monitoring detection request to the video networking monitoring server, and the video networking monitoring server sends the monitoring detection request to the first monitoring access server based on the video networking protocol.

The monitoring detection request may include information such as an identifier of the target monitoring resource and an identifier of the first monitoring access server. The first monitoring access server determines a target monitoring resource according to the monitoring detection request, for example, an identifier of the target monitoring resource included in the monitoring detection request may be read, and determines that the monitoring resource corresponding to the identifier of the target monitoring resource is the target monitoring resource.

step 602, the first monitoring access server determines whether the video data of the target monitoring resource meets a preset alarm condition. If yes, go to step 603; if not, go to step 606.

In a preferred embodiment, the alarm condition may be set such that the number of people in the video data exceeds a set threshold. Thus, this step 602 may include:

The first monitoring access server can find the target monitoring resource according to the identifier of the target monitoring resource, execute a stream pulling operation aiming at the target monitoring resource, and pull the video data of the target monitoring resource, namely the video stream collected by the target monitoring resource. In a specific implementation manner, the first monitoring access server may read an identifier of the target monitoring resource from the monitoring detection request, obtain a pull flow address of the target monitoring resource according to the identifier of the target monitoring resource, and generate a pull flow request including information such as the identifier of the target monitoring resource, the pull flow address, the identifier of the first monitoring access server, and the like; the first monitoring access server sends a pull flow request to a target monitoring resource; and the target monitoring resource returns the corresponding video data to the first monitoring access server aiming at the pull stream request.

a2, the first monitoring access server obtains the number of people in the video data.

In one specific implementation, step a2 may include: the first monitoring access server converts the video data into image data with a set format; and the first monitoring access server calls a preset algorithm to analyze the image data to obtain the number of people in the image data, and the number of people in the image data is used as the number of people in the video data.

For example, the number of people in the video data can be obtained by adopting a face recognition SDK algorithm, and the SDK algorithm can be used for recognizing the image data after the image data in the YUV format is input, so as to obtain the number of people in the image data. In the video network, the video data collected by the monitoring resource can be in an H.264 format, so that the first monitoring access server can convert the video data in the H.264 format into image data in a YUV format, and then the SDK algorithm is called to analyze the image data to obtain the number of people in the image data. For the above process of converting the video data in the h.264 format into the image data in the YUV format, a person skilled in the art may select any suitable conversion mode according to practical experience, for example, the format conversion may be performed by using the techniques such as FFmpeg, and the embodiment of the present invention is not limited thereto. For the above process of analyzing the image data to obtain the number of people in the image data by invoking the SDK algorithm, a person skilled in the art may perform the correlation processing according to actual experience, and the embodiment of the present invention is not discussed in detail herein.

a3, when the number of people is judged to exceed a set threshold value, the first monitoring access server determines that the video data of the target monitoring resource meets the preset alarm condition.

For the specific value of the set threshold, a person skilled in the art may select any suitable value according to practical experience, for example, the value may be set to 5, 10, 15, and the like, which is not limited in this embodiment of the present invention.

in another preferred embodiment, the alarm condition may be set to the presence of a preset picture in the video data. Thus, this step 602 may include:

b1, the first monitoring access server pulls the video data of the target monitoring resource.

The specific process of b1 is substantially similar to that of a1, and can be specifically referred to the related description of a 1.

b2, the first monitoring access server detects whether there is a preset picture in the video data.

In a specific implementation, step b2 may include: the first monitoring access server converts the video data into image data with a set format; the first monitoring access server calls a preset image recognition algorithm to analyze the image data, detects whether a preset picture exists in the image data, and determines that the preset picture exists in the video data if the preset picture exists in the image data. The preset image can be a flame image, a smoke image, etc. The set format can be any suitable image format, such as YUV format, JPEG format, and the like. For a specific process of analyzing the image data and detecting whether the preset picture exists in the image data, a person skilled in the art may perform related processing according to actual experience, and the embodiment of the present invention is not discussed in detail herein.

b3, when the first monitoring access server judges that a preset picture exists, determining that the video data of the target monitoring resource meets the preset alarm condition.

And 603, after the first monitoring access server judges that the condition is met, generating alarm information and returning the alarm information to the video network monitoring and networking management platform.

if the first monitoring access server determines that the preset alarm condition is met in step 602, generating corresponding alarm information, where the alarm information may include information such as an identifier of the target monitoring resource and alarm content.

And the first monitoring access server returns the alarm information to the video networking monitoring networking management platform based on the video networking protocol. For example, the first monitoring access server can return the alarm information to the video networking monitoring server of the video networking monitoring management platform based on the video networking protocol, and then the first monitoring access server is pushed to the video networking monitoring client of the video networking monitoring management platform by the video networking monitoring server.

Step 604, the second monitoring access server receives a monitoring viewing request which is generated by the video network monitoring and network managing platform for the alarm information and is sent by the video network terminal, and determines the target monitoring resource according to the monitoring viewing request.

After receiving the alarm information, the video networking monitoring and networking management platform can automatically generate a monitoring and viewing request aiming at the alarm information, send the monitoring and viewing request to the video networking terminal based on the video networking protocol, and then send the monitoring and viewing request to the second monitoring access server by the video networking terminal based on the video networking protocol.

After receiving the alarm information, the video network monitoring and networking management platform can also display the alarm information in a user interface provided by a video network monitoring client, a viewing button can be further provided in the user interface, a user can trigger a monitoring viewing request aiming at a target monitoring resource by clicking the viewing button, the video network monitoring client sends the monitoring viewing request to a video network monitoring server of the video network monitoring and networking management platform, the video network monitoring server sends the monitoring viewing request to a video network terminal based on a video network protocol, and the video network terminal sends the monitoring viewing request to a second monitoring access server based on the video network protocol.

The monitoring and viewing request may include information such as an identifier of the target monitoring resource, an identifier of the video network terminal, and an identifier of the second monitoring access server. And the second monitoring access server determines the target monitoring resource according to the monitoring check request, for example, the identifier of the target monitoring resource included in the monitoring check request can be read, and the monitoring resource corresponding to the identifier of the target monitoring resource is determined as the target monitoring resource.

And 605, the second monitoring access server issues the video data of the target monitoring resource and returns the viewing information corresponding to the video data to the video network terminal.

In a preferred embodiment, the step of the second monitoring access server publishing the video data of the target monitoring resource may include: the second monitoring access server pulls the video data of the target monitoring resource; and the second monitoring access server sends the video data to a virtual terminal in the video network.

The process of the second monitoring access server pulling the video data of the target monitoring resource may include: the second monitoring access server reads the identification of the target monitoring resource from the monitoring viewing request, acquires the pull flow address of the target monitoring resource according to the identification of the target monitoring resource, and generates a pull flow request comprising the identification of the target monitoring resource, the pull flow address, the identification of the second monitoring access server and other information; the second monitoring access server sends the pull flow request to the target monitoring resource; and the target monitoring resource returns the corresponding video data to the second monitoring access server aiming at the pull stream request.

the video network can comprise a plurality of virtual terminals, each virtual terminal has a corresponding number, video data collected by the monitoring resource can be issued to the virtual terminals, and users of the video network terminals can acquire the monitoring data from the virtual terminals for viewing. After the second monitoring access server pulls the video data, the video data can be sent to the idle virtual terminal in the video network.

The second monitoring access server can also return viewing information corresponding to the video data to the video network terminal. Specifically, the method may include the step of acquiring a number of the virtual terminal by the second monitoring access server, and returning the number as the viewing information to the video networking terminal based on the video networking protocol. The video network terminal reads the virtual terminal number according to the viewing information, acquires the video data of the target monitoring resource from the virtual terminal corresponding to the number, plays the video data, and the user of the video network terminal can view the video data on the video network terminal to complete the monitoring viewing process of the embodiment of the invention.

And 606, after the first monitoring access server judges that the instruction is not satisfied, judging whether a stop instruction sent by the video networking monitoring networking management platform is received. If yes, go to step 607; if not, return to step 602.

And if the first monitoring access server judges that the preset alarm condition is not met, the first monitoring access server does not return alarm information to the video networking monitoring and managing platform. If the video network monitoring and networking management platform does not receive the alarm information returned by the first monitoring access server, the video network monitoring and networking management platform can know that the currently detected monitoring resource does not meet the preset alarm condition, and under the condition, the video network monitoring and networking management platform can determine whether to continue to detect according to the actual condition so as to determine whether to send a stop instruction.

For example, the video networking monitoring and networking management platform may automatically generate a stop instruction after determining that a preset stop condition is met, where the preset stop condition may be set to reach a set time (e.g., 0.5 hour, 1 hour, 2 hours, etc.), and a person skilled in the art may perform relevant settings according to actual experience. For another example, the internet of view monitoring management platform may further provide a stop button in a user interface provided by the internet of view monitoring client, and a user may trigger the stop instruction by clicking the stop button.

The internet of view monitoring management platform may send a stop instruction to the first monitoring access server based on the internet of view protocol to instruct the first monitoring access server to stop executing the determination process of step 602. The stop instruction may include information such as an identifier of the target monitoring resource, an identifier of the first monitoring access server, and the like.

if the first monitoring access server determines that the preset alarm condition is not met in step 602, the first monitoring access server determines whether a stop instruction sent by the video networking monitoring and networking management platform is received. If yes, go to step 607; if not, the determination process of step 602 continues.

step 607, the first monitoring access server stops determining whether the video data of the target monitoring resource meets the preset alarm condition.

And after receiving the stop instruction, the first monitoring access server stops judging whether the video data of the target monitoring resource meets the preset alarm condition or not, so that the resource is released, and the resource waste is avoided.

The deployment scheme of the embodiment of the invention adopts two monitoring access servers, one for analyzing and monitoring to generate an alarm and the other for releasing and monitoring live broadcast. The arrangement has no influence on the original watching monitoring, the phenomenon of blocking can not occur, the load of the same monitoring access server can be reduced, and the system is convenient, flexible and convenient to expand.
