2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.

Based on the characteristics of the video networking, one of the core concepts of the embodiment of the invention is provided, the PCTV monitors the target time of unmanned operation according to the protocol of the video networking, when the target time exceeds the set time, the PCTV generates the alarm information, the streaming media server converts the alarm information into the alarm data packet of the video networking protocol, sends the alarm data packet of the video networking protocol to the monitoring management platform, and the monitoring management platform converts the alarm data packet of the video networking protocol into the alarm data packet of the internet protocol and sends the alarm data packet of the internet protocol to the front end of the webpage for displaying.

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

step 501, the PCTV monitors the target time of unmanned operation.

PCTV is just a computer TV (PC i.e. computer, TV i.e. television). The PCTV has both the television function and the VCD and DVD playing function, and also has some functions of a computer, such as game, communication, word processing, management, and receiving various information from the internet.

In an embodiment of the present invention, the PCTV is used by a user as a working device. The PCTV can continuously monitor the working state of a user, for example, monitor the action of the user for not operating the PCTV, and record the target time of the non-operation action duration, namely, record the target time of the PCTV for no-operation.

Optionally, the PCTV monitors a target time for unattended operation, comprising: the PCTV monitors a target time for which a mouse is not moved on a screen.

In the embodiment of the invention, the PCTV continuously monitors the motion state of the mouse on the screen, and if the mouse on the PCTV screen is not moved, the PCTV is considered to be operated by no person. And the PCTV monitors the target time of mouse immobility on the screen, namely the target time for monitoring the unmanned operation of the PCTV.

Step 502, when the target time exceeds the set time, the PCTV generates an alarm message.

In the embodiment of the invention, when the PCTV records that the target time of the PCTV unmanned operation exceeds the set time, the warning information is immediately generated. For example, if the PCTV monitors that the target time of the unmanned operation reaches the set time 20 minutes, it is considered that the non-operation behavior of the user is abnormal. For example, a non-operational behavior of more than 20 minutes may be considered to represent that the user is not in a normal working state, that the user may have left the working position or that the user is dozing off at the working position, which are abnormal working states. At this time, the PCTV generates an alarm message for the abnormal operation state.

Optionally, when the target time exceeds a set time, the PCTV generating the warning information includes:

In the embodiment of the invention, when the PCTV records that the target time of the PCTV unmanned operation exceeds the set time, the PCTV is confirmed to be unmanned operation, and the current abnormal condition is confirmed. At this time, the PCTV generates the warning information, which includes the target path to which the warning information is sent, i.e., the monitoring management platform of the video network, and the account number of the PCTV, so that a party receiving the warning information can know the source of the warning information and locate the user bound to the PCTV through the account number of the PCTV. The alarm information may also include time of alarm generation and description of specific abnormal conditions monitored by the PCTV, and the description information may be, for example: the machine is unmanned for 20 minutes.

Optionally, the PCTV monitors whether a current user operation is a locally bound user operation; and if the current user operation is not the operation of the user bound by the PCTV, generating alarm information by the PCTV.

In the embodiment of the invention, the PCTV can bind the operation users in advance, only the locally bound user can operate the PCTV, if the current user operation is not the operation of the locally bound user, the situation of replacing work is considered to possibly occur, and the locally bound user is represented not to be in a normal working state.

For such abnormal operating state, the PCTV generates an alarm message.

Similarly, the alarm information may also include a target path to which the alarm information is to be sent, an account number of the PCTV, a time when the alarm is generated, and a description of a specific abnormal condition monitored by the PCTV, for example, the description information may be: the native current user operation is not that of the native bound user.

Optionally, the PCTV monitoring whether the current user operation is an operation of a native bound user, including: the PCTV identifies whether the current user is a locally bound user through a camera to determine whether the current user operation is the locally bound user operation.

In the embodiment of the present invention, the PCTV may have a camera, and the camera may take a picture of or take a picture of a current operation user. And the PCTV prestores images of users bound to the computer, can carry out feature matching on the camera shooting or the picture taking and the images of the users bound to the computer, and once the images are not matched, the current user operation is not the operation of the users bound to the computer.

Optionally, the PCTV determines whether the current user operation is the operation of the locally bound user according to the operation habit of the locally bound user recorded in advance.

In the embodiment of the present invention, the PCTV may count and record the operation habits of the locally bound users in advance, for example, the operation habits of the users may be determined based on the same and/or different operations of the users for one application and the statistical results of the same and/or different operations for different applications. When a user operates the PCTV, the PCTV compares the operation habit of the current user with the operation habit of a local binding user prestored in the system, and if the operation habit of the current user is inconsistent with the operation habit of the binding user prestored in the PCTV, the current user operation is not the operation of the local binding user.

Step 503, the PCTV sends the warning information to the streaming media server.

In the embodiment of the invention, the streaming media server is a terminal device in the video network, can collect, cache, schedule, transmit and play streaming media contents, and is a key platform for providing video services for users.

The PCTV is a device in the internet, and the streaming server may be connected to a plurality of PCTVs. After the PCTV generates the alarm information, the alarm information is sent to the streaming media server in the format of an Internet protocol data packet.

Step 504, the streaming media server converts the alarm information into an alarm data packet of a video networking protocol.

In the embodiment of the invention, the streaming media server has the function of protocol conversion, and because the video network does not support the transmission of the data packet of the internet protocol, the streaming media server converts the alarm information data packet of the internet protocol into the alarm information data packet of the video network protocol. Specifically, the streaming media server removes the IP packet header of the alarm information packet, replaces the IP packet header with the packet header of the video networking protocol, and encapsulates the entire data packet in the video networking message body.

And 505, the streaming media server sends the alarm data packet of the video networking protocol to a monitoring management platform.

The monitoring management platform is responsible for the unified management of all accessed monitoring equipment in the video network and the docking service of other third-party monitoring systems. In the embodiment of the invention, the monitoring management platform can receive the warning information of the PCTV, so that a manager can master the abnormal condition monitored by the PCTV.

The communication between the streaming media server and the monitoring management platform uses the 8F85 protocol of video networking, and the specification of the 8F85 protocol can be shown as the following table:

the 8F85 protocol is short signaling with length of 32W, wherein the opt _ para opcode field can carry an operation instruction. In the embodiment of the present invention, the signaling of the 8F85 protocol carries an alarm information packet of a video networking protocol, and is sent to the monitoring management platform by the streaming media server.

Step 506, the monitoring management platform analyzes the alarm information data packet.

In the embodiment of the present invention, the process of analyzing the alarm information data packet by the monitoring management platform may be that the monitoring management platform puts the received video networking information data packets into the storage area first, then takes out the alarm information data items from the storage area one by one, removes the packet header of the video networking protocol in each data item, reads the data content field from the message body of the data item, and extracts the alarm information to form the analysis result.

Considering that there may be a plurality of PCTVs simultaneously transmitting the alarm information, the monitoring management platform may create an alarm information queue in the storage area. And each time an alarm message is received, putting the alarm message into an alarm message queue. Then, the monitoring management platform starts a separate thread to analyze each data item of the queue one by one.

And 507, the monitoring management platform converts the analyzed alarm data packet into an alarm information data packet of an internet protocol.

In the embodiment of the invention, the monitoring management platform also has a protocol conversion function and can perform mutual conversion of a video networking protocol format and an internet protocol format on the alarm information data packet. Because the monitoring management platform is a management background, if a manager wants to acquire the alarm information, the manager needs to send the analysis result of the alarm information to the display terminal for viewing. Because the communication between the monitoring management platform and the display terminal is based on the internet protocol, the monitoring management platform needs to firstly convert the alarm information data packet of the video networking protocol into the alarm information data packet of the internet protocol.

Optionally, before the monitoring management platform converts the analyzed alarm information data packet into an alarm information data packet of an internet protocol, the method further includes: and the webpage front end sends a GET request to the monitoring management platform, and data transmitted in the GET request is in a JSON format.

In the embodiment of the invention, the front end of the webpage is a display terminal, and the front end of the webpage is a network page which can be browsed and used through a browser and can be supported by a computer, a tablet computer, a mobile terminal and the like. To acquire the warning information, the front end of the web page may first send a GET request based on an HTTP (HyperText Transfer Protocol) Protocol to the monitoring management platform, where the GET request includes an instruction that the monitoring management platform needs to execute. In addition, since JSON (JSON Object Notation) is a lightweight data exchange format, which is simple, easy to operate, and has less redundant data, the data transmitted in the GET request can be selected to use the JSON format.

Specifically, the front end of the web page may have a button for acquiring the warning information, and when the manager clicks the button, a GET request message instructing the monitoring management platform to send the warning information to the monitoring management platform is generated.

And step 508, the monitoring management platform sends the alarm data packet of the internet protocol to the front end of the webpage for display.

In the embodiment of the invention, because the monitoring management platform carries out the conversion of the Internet protocol format on the alarm information, the alarm information data packet of the Internet protocol can be directly sent to the front end of the webpage for display. Specifically, the warning information may be presented at the front end of the web page in a form of a pop-up box, and after the pop-up box is clicked, detailed warning information content may be displayed, for example, a PCTV account generating a warning, a warning time, description information of a specific abnormal situation, and the like are displayed. Thus, the manager is informed of the abnormality monitored by the PCTV.

In summary, in the embodiment of the present invention, a PCTV monitors target time of unmanned operation, and when the target time exceeds a set time, the PCTV generates alarm information, a streaming media server converts the alarm information into an alarm data packet of a video networking protocol, and sends the alarm data packet to a monitoring management platform, and the monitoring management platform analyzes the alarm data packet, converts the analyzed alarm data packet into an alarm data packet of an internet protocol, and sends the alarm data packet to a front end of a web page for display; by the embodiment of the invention, the warning information generated by the PCTV in the Internet is displayed at the front end of the webpage of the video network, so that a manager at the front end of the webpage can acquire the abnormal condition monitored by the PCTV.
