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 above characteristics of the video network, the monitoring recording scheme provided by the embodiment of the invention follows the protocol of the video network, and plays the monitoring video stream through the IE plug-in, so that the user can view the monitoring video locally.

The monitoring and recording scheme of the embodiment of the invention can be applied to the video network. The video network of the embodiment of the invention can comprise a video network monitoring and dispatching platform, a monitoring and sharing platform, a monitoring access server and monitoring equipment, and the video network monitoring and dispatching platform can comprise a monitoring and dispatching client and a monitoring and dispatching server. The monitoring and dispatching client side and the monitoring and dispatching server can interact based on an internet protocol, the monitoring and dispatching server and the monitoring and sharing platform can interact based on the internet protocol, the monitoring and sharing platform and the monitoring and accessing server can interact based on the internet protocol, the monitoring and accessing server and the monitoring equipment can interact based on the internet protocol, and the monitoring and dispatching client side can interact based on the internet protocol.

Example one

Referring to fig. 5, a flowchart illustrating steps of a monitoring playing method according to a first embodiment of the present invention is shown. The monitoring recording method of the embodiment of the invention can comprise the following steps:

step 501, after the IE plugin is started, receiving information of the target monitoring device and generating a play request for the target monitoring device.

In the embodiment of the invention, the IE browser and the IE plug-in can be installed in the monitoring and scheduling client of the video networking monitoring and scheduling platform in advance. The IE plug-in is a plug-in used in an IE browser and can realize local playing of monitoring videos at a monitoring scheduling client. The monitoring and scheduling client may be a Web end or a mobile end, which is not limited in this embodiment of the present invention.

The user can perform relevant operations in the front page of the IE browser so as to trigger the IE browser to start the IE plugin. The user can also execute relevant operations in the front-end page of the IE browser so as to trigger the IE browser to send the information of the target monitoring device to the IE plugin. After receiving the information of the target monitoring device, the IE plugin may generate a play request for the target monitoring device according to the information of the target monitoring device. The play request may include information of the target monitoring device, such as an identifier of the target monitoring device.

Step 502, the IE plug-in sends the play request to the monitoring scheduling server through the first internet protocol, and sends the play request to the monitoring sharing platform through the monitoring scheduling server through the video networking protocol.

In the specific implementation, the monitoring and scheduling server can serve as an Mserver, is a background service of a video networking monitoring and scheduling platform, and can be mainly used for processes of resource access, synchronization, flow regulation and the like of monitoring equipment.

The IE plug-in and the monitoring scheduling server can interact through a first internet protocol, and the monitoring scheduling server and the monitoring sharing platform can interact through a video networking protocol. After the IE plug-in generates the playing request, the playing request can be sent to the monitoring scheduling server through the first internet protocol, and the monitoring scheduling server sends the playing request to the monitoring sharing platform through the video networking protocol.

In step 503, the IE plug-in receives the monitoring video stream of the target monitoring device returned by the monitoring sharing platform through the second internet protocol for the play request.

In a specific implementation, the monitoring sharing platform may be in the form of a monitoring sharing server. The monitoring sharing platform can realize the access of the resources of the monitoring equipment accessed by the monitoring access server through the video networking protocol and the push-out through the Internet protocol. The monitoring access server is an entrance for accessing the monitoring equipment into the video network, and can be accessed into various types of monitoring equipment, so that the resources of the monitoring equipment are accessed through an internet protocol and are released through the video network protocol.

The monitoring sharing platform and the monitoring access server can interact through a video networking protocol, and the monitoring sharing platform and the IE plug-in can interact through an Internet protocol. And after receiving the playing request, the monitoring sharing platform acquires the monitoring video stream of the target monitoring equipment from the monitoring access server through the video networking protocol according to the playing request, and returns the acquired monitoring video stream to the IE plug-in unit through the second Internet protocol. The target monitoring device can be a network camera or the like.

And step 504, the IE plug-in plays the monitoring video stream.

And the IE plug-in receives the monitoring video stream returned by the monitoring sharing platform and can play the monitoring video stream. The user can view the monitoring video locally at the monitoring client.

In the embodiment of the invention, the monitoring video is locally played at the monitoring scheduling client through the IE plug-in, so that the video network terminal does not need to be bound, the process of viewing the monitoring video is simpler and more convenient, and the flexibility is higher.

Example two

Referring to fig. 6, a flowchart illustrating steps of a monitoring playing method according to a second embodiment of the present invention is shown. The method can be applied to video networking.

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

step 601, after receiving the plug-in starting instruction, the IE browser calls a preset plug-in playing video interface to start the IE plug-in.

An IE browser and an IE plugin can be installed in the monitoring and scheduling client, when the IE plugin is installed, a user can input configuration information in an operation page provided by the monitoring and scheduling client, the configuration information can include information such as an IP address (such as an IP address of an Mserver), an ID (identity) and a port of a monitoring and scheduling server, and the configuration information is stored in a monitoring and scheduling database of the video network monitoring and scheduling platform.

In a preferred embodiment, the monitoring scheduling client may provide a resource list page, and the resource list page may record relevant information of the monitoring device, such as an identifier, a name, a working state, and an identifier of a monitoring access server accessed by the monitoring device. A play button may also be provided in the resource list page for the monitoring device. The user can trigger the plug-in starting instruction by executing relevant operations on the monitoring scheduling client. For example, a user may open a resource list page with an IE browser at the monitoring and scheduling client, and a plug-in start instruction may be triggered by the act of opening the resource list page with the IE browser. For another example, after the resource list page is opened by the IE browser, the user may click a play button, and the action of clicking the play button may trigger the plug-in start instruction.

After receiving the plug-in starting instruction, the IE browser can read preset configuration information from the monitoring scheduling database and call a preset plug-in playing video interface to start the IE plug-in according to the configuration information.

Step 602, after the IE plugin is started, receiving information of the target monitoring device and generating a play request for the target monitoring device.

And after opening the resource list page by using the IE browser, the user clicks a play button and selects target monitoring equipment to be played. For example, the user may select a target monitoring device from the monitoring device related information displayed on the resource list page. As another example, an input module (e.g., input box) may be provided in the resource list page, where the user may enter information for the target monitoring device.

The IE browser can acquire the information of the target monitoring device selected by the user and send the information to the IE plugin. And the IE plug-in receives the information of the target monitoring equipment and generates a playing request aiming at the target monitoring equipment. In a specific implementation, the IE plug-in may generate a play request based on an internet protocol and including information of the target monitoring device.

And 603, the IE plug-in sends the playing request to the monitoring scheduling server through the first Internet protocol, and sends the playing request to the monitoring sharing platform through the monitoring scheduling server through the video networking protocol.

The IE plug-in and the monitoring scheduling server can realize bidirectional interaction through a first internet protocol. In this embodiment of the present invention, the first Internet Protocol may be a Session Initiation Protocol (SIP), which is a multimedia communication Protocol established by an IETF (Internet Engineering Task Force), and is a text-based application layer control Protocol for creating, modifying, and releasing a Session of one or more participants. Certainly, bidirectional interaction between the IE plugin and the monitoring scheduling server may also be realized through other internet protocols, such as HTTP (Hyper Text transfer Protocol), and the like.

Therefore, the play request generated by the IE plugin may be a play request based on the first internet protocol, and the IE plugin sends the play request based on the first internet protocol to the monitoring scheduling server through the first internet protocol according to the configuration information. The monitoring scheduling server and the monitoring sharing platform are interacted through a video networking protocol, so that the monitoring scheduling server can convert the playing request based on the first internet protocol into the playing request based on the video networking protocol after receiving the playing request based on the first internet protocol, and send the playing request based on the video networking protocol obtained through conversion to the monitoring sharing platform through the video networking protocol.

And step 604, the IE plug-in receives the monitoring video stream of the target monitoring device returned by the monitoring sharing platform through the second Internet protocol according to the playing request.

And after receiving the playing request based on the video networking protocol, the monitoring sharing platform acquires the monitoring video stream of the target monitoring equipment from the monitoring access server through the video networking protocol. The method specifically comprises the following steps: the monitoring sharing platform sends a playing request based on the video networking protocol to a monitoring access server through the video networking protocol; the monitoring access server reads information (such as identification of the target monitoring equipment) of the target monitoring equipment from the playing request, converts the playing request based on the video networking protocol into the playing request based on the internet protocol, and sends the playing request based on the video networking protocol to the target monitoring equipment corresponding to the information through the internet protocol; after receiving the playing request, the target monitoring equipment returns the monitoring video stream based on the Internet protocol to the monitoring access server through the Internet protocol; the monitoring access server converts the monitoring video stream based on the Internet protocol into a monitoring video stream based on the video networking protocol, and sends the monitoring video stream based on the video networking protocol to the monitoring sharing platform. The internet protocol for interaction between the monitoring access server and the monitoring device may be h.323 protocol or SIP protocol.

Specifically, the IE plugin sends the control instruction to the monitoring scheduling server through the first internet protocol, and sends the control instruction to the target monitoring device through the monitoring scheduling server, the monitoring sharing platform, and the monitoring access server in sequence, so that the target monitoring device responds to the control instruction.

The control instruction may be a control instruction based on a first internet protocol, and the IE plugin sends the control instruction based on the first internet protocol to the monitoring scheduling server through the first internet protocol. The monitoring scheduling server and the monitoring sharing platform are interacted through a video networking protocol, so that the monitoring scheduling server can convert the control instruction based on the first internet protocol into the control instruction based on the video networking protocol after receiving the control instruction based on the first internet protocol, and sends the converted control instruction based on the video networking protocol to the monitoring sharing platform through the video networking protocol. And the monitoring sharing platform sends the control instruction based on the video networking protocol to the monitoring access server through the video networking protocol. The monitoring access server reads the information (such as identification and the like) of the target monitoring device from the control instruction, converts the control instruction based on the video networking protocol into the control instruction based on the internet protocol (such as H.323 protocol or SIP protocol), and sends the control instruction to the target monitoring device through the internet protocol. And after receiving the control instruction based on the Internet protocol, the target monitoring equipment responds to the control instruction and executes corresponding action.

In a preferred embodiment, a control interface corresponding to a target monitoring device may be displayed in an IE browser, a user may perform a related operation on the control interface to trigger a control instruction for the target monitoring device, and the IE browser sends the control instruction to an IE plug-in.

For example, the control interface may display orientation control buttons, which may include four orientation control buttons, i.e., up, down, left, and right. The user can trigger the position control instruction corresponding to the position by clicking a certain position control button, and the position control instruction can comprise a moving direction and a preset moving distance. And after receiving the direction control instruction, the IE plug-in controls the target monitoring equipment to move the moving distance to the moving direction according to the direction control instruction. The method specifically can also comprise the following steps: and the IE plug-in sends the direction control instruction to the target monitoring equipment through the transmission process of the control instruction, and the target monitoring equipment responds to the direction control instruction, reads the moving direction and the moving distance from the direction control instruction and automatically moves the moving distance to the moving direction. For the above moving distance, those skilled in the art may perform relevant setting according to practical experience, for example, the setting may be 3cm, 5cm, 7cm, and the like, and the embodiment of the present invention does not limit the specific value.

For another example, the control interface may display an orientation control button, which may include four orientation control buttons, i.e., up, down, left, and right. The user can press a certain direction control button to trigger a starting control instruction corresponding to the direction, and the starting control instruction can also comprise the moving direction. And after receiving the starting control instruction, the IE plug-in controls the target monitoring equipment to continuously move towards the moving direction according to the starting control instruction. The method specifically comprises the following steps: and the IE plug-in sends the starting control instruction to the target monitoring equipment through the transmission process of the control instruction, and the target monitoring equipment responds to the starting control instruction, reads the moving direction from the starting control instruction and automatically and continuously moves towards the moving direction. The user may release the depressed orientation button to trigger an end control command corresponding to the orientation, which may include a direction of movement. And after receiving the ending control instruction, the IE plug-in controls the target monitoring equipment to stop moving towards the moving direction according to the ending control instruction. The method specifically comprises the following steps: and the IE plug-in sends the ending control instruction to the target monitoring equipment through the transmission process of the control instruction, and the target monitoring equipment responds to the ending control instruction, reads the moving direction from the ending control instruction and stops moving towards the moving direction.

The direction of the target monitoring equipment can be changed through the control process so as to check the monitoring video stream collected by the target monitoring equipment in other directions.
