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 data synchronization scheme provided by the embodiment of the invention follows the protocol of the video network, and can ensure the accuracy of monitoring data in a GIS (Geographic Information System) platform.

The video network monitoring and dispatching platform, the video network server (which may be a node server in fig. 1) and the monitoring protocol server are included in the video network, and the monitoring protocol server is connected with a plurality of monitoring devices.
The monitoring protocol server can be understood as a gateway, and is responsible for accessing external monitoring equipment (such as on the internet) into the video networking monitoring scheduling platform. The monitoring equipment encodes the collected monitoring video based on the corresponding internet protocol, the monitoring protocol conversion server can acquire the monitoring video encoded by the monitoring equipment based on the internet protocol, the monitoring protocol conversion server can convert the monitoring video based on the internet protocol into the monitoring video based on the video networking protocol, and then the monitoring video is sent to the video networking monitoring and dispatching platform, so that the monitoring equipment on the internet can be browsed and controlled in the video networking.
The monitoring protocol server may be connected to a plurality of monitoring devices. Therefore, the monitoring coordination server can record data of a plurality of monitoring devices connected with the monitoring coordination server. The monitoring co-transformation server can also be connected with at least one third-party monitoring platform located in the internet, and the third-party monitoring platform is connected with a plurality of monitoring devices. Therefore, the monitoring co-transformation server can record data of a plurality of monitoring devices connected through the third-party monitoring platform, so that the video network monitoring platform is in butt joint with the third-party monitoring platform, and the video network and the monitoring devices in the internet are shared. The third-party monitoring platform can be a public security monitoring platform, a medical monitoring platform, and the like.
The monitoring protocol conversion server and the video network monitoring and dispatching platform can interact through the video network server.

The video network monitoring client can be a Web end, and the video network monitoring server can be an Mserver. The video network monitoring client mainly provides interaction with users. The video network monitoring server can be connected with the video network server and is mainly used for providing interaction with the video network server, and the video network monitoring server can acquire data of each monitoring device from the monitoring coordination server through the video network server. The video network monitoring database can be connected with the video network monitoring server and is mainly used for storing monitoring data, and the monitoring data comprises data of each monitoring device so that the video network monitoring server can perform operations such as inquiry and modification. In addition, the video networking monitoring and scheduling platform can update the monitoring data stored in the video networking monitoring database in time when the data of the monitoring equipment in the monitoring coordination server changes.
The internet includes a GIS platform. The GIS platform can include a GIS client, a GIS server and a GIS database. The GIS client mainly provides interaction with the user. The GIS server can be connected with a video network monitoring server of the video network monitoring and dispatching platform and is mainly used for providing interaction with the video network monitoring and dispatching platform. The GIS database can be connected with the GIS server and is mainly used for storing monitoring data so that the GIS server can perform operations such as inquiry, modification and the like.
Referring to fig. 5, a flowchart illustrating steps of a monitoring data synchronization method according to an embodiment of the present invention is shown.
The monitoring data synchronization method of the embodiment of the invention can comprise the following steps:
The GIS platform can acquire the monitoring data in the video network monitoring and scheduling platform. The monitoring data may include data of the monitoring device, such as device identification (name, ID, etc.), geographical location, operational status, etc. information. However, in practical applications the monitoring data may change. For example, the change may be the addition of one or more monitoring devices, the deletion of one or more monitoring devices, or a change in the status of one or more monitoring devices. The state change may be that the state of the monitoring device is changed from online to offline due to disconnection of a network or the like, or the state of the monitoring device is changed from offline to online due to reconnection of a network or the like, or the like. Therefore, the GIS platform can synchronize the monitoring data.
The GIS platform can register on the video network monitoring and dispatching platform in advance to obtain a registered account number, a password and the like. A user interface can be provided on a GIS client of the GIS platform, a login page can be displayed on the user interface, and a user can input information such as a registered account number and a password on the login page so as to log in the video network monitoring and scheduling platform. A synchronous operation page can be further displayed on the user interface, and a user can perform corresponding operation on the synchronous operation page so as to trigger the monitoring synchronous request. For example, a monitoring data synchronization option (such as a monitoring data synchronization button) and a terminal data synchronization option (such as a terminal data synchronization button) may be provided on the synchronization operation page, and the user may select the monitoring data synchronization option to trigger the monitoring synchronization request.
A preset interface can be provided on the video network monitoring and dispatching platform, and the GIS platform and the video network monitoring and dispatching platform can interact through the preset interface. After receiving the monitoring synchronization request, the GIS platform can switch the data source to the video network monitoring and scheduling platform, call a preset interface provided by the video network monitoring and scheduling platform, and send the monitoring synchronization request based on the video network protocol to the video network monitoring and scheduling platform through the video network.
And after receiving the monitoring synchronization request, the video networking monitoring and scheduling platform analyzes the monitoring synchronization request to obtain the data to be monitored synchronously. Therefore, the video networking monitoring and scheduling platform can acquire the first monitoring data based on the video networking protocol.
In an optional implementation manner, the video networking monitoring server of the video networking monitoring scheduling platform can acquire the first monitoring data based on the video networking protocol from the video networking monitoring database. The first monitoring data based on the video networking protocol in the video networking monitoring database is the first monitoring data based on the video networking protocol acquired from the monitoring protocol conversion server by the video networking monitoring server through the video networking server. The first monitoring data includes data of a plurality of monitoring devices connected to the monitoring protocol server.
In another optional implementation manner, the video networking monitoring server of the video networking monitoring and scheduling platform may send the synchronization request to the video networking server, the video networking server obtains the first monitoring data based on the video networking protocol from the monitoring coordination server in real time according to the synchronization request, the video networking server returns the first monitoring data based on the video networking protocol to the video networking monitoring server, and the video networking monitoring server may further store the first monitoring data based on the video networking protocol to the video networking monitoring database.
The video networking monitoring and dispatching platform and the GIS platform are in bidirectional interaction based on an internet protocol. Therefore, the video networking monitoring and scheduling platform can perform protocol conversion on the first monitoring data based on the video networking protocol to obtain the first monitoring data based on the internet protocol. In implementation, a video networking monitoring and scheduling platform (specifically, a video networking monitoring server) analyzes first monitoring data (that is, a video networking protocol data packet) based on a video networking protocol to obtain the first monitoring data included therein, and encapsulates the first monitoring data based on an internet protocol to obtain first monitoring data (that is, an internet protocol data packet) based on the internet protocol. After the conversion, the video networking monitoring and scheduling platform returns the first monitoring data based on the Internet protocol to the GIS platform.
In an alternative embodiment, in consideration that the data volume of the monitoring data may be large, the embodiment of the present invention may adopt a paging synchronization manner. Therefore, the monitoring synchronization request may include a synchronization mode being paging synchronization, and a corresponding paging data amount, for example, the paging data amount may be 1 ten thousand, 1.5 ten thousand, and the like, which is not limited in this embodiment of the present invention.
Therefore, after receiving the monitoring synchronization request, the video networking monitoring and scheduling platform acquires the first monitoring data based on the video networking protocol of the paging data volume aiming at the monitoring synchronization request, and converts the acquired first monitoring data based on the video networking protocol into the first monitoring data based on the internet protocol. And after conversion, returning the first monitoring data of the paging data volume based on the Internet protocol to the GIS platform.
Because the data format that the video networking monitoring and dispatching platform can process is different from the data format that the GIS platform can process, after receiving the first monitoring data based on the internet protocol that the video networking monitoring and dispatching platform returns, the GIS platform converts the format of the first monitoring data based on the internet protocol into the format that is supported by the GIS platform. The formats supported by the GIS platform may include shp (coordinate file),. dbf (attribute file),. shx (index file), etc.
For the specific process of format conversion, those skilled in the art can use any suitable method according to practical experience, for example, format conversion can be performed by using a suitable format conversion tool, and the embodiment of the present invention is not discussed in detail herein.
The GIS platform can receive first monitoring data based on an internet protocol returned by the video networking monitoring and scheduling platform through the GIS server, and format conversion is carried out on the first monitoring data. The GIS platform can clear the second monitoring data stored in the GIS database. The GIS server can store the first monitoring data after format conversion into a GIS database, so that the first monitoring data can be synchronized.
During storage, the GIS server may store the first monitoring data after format conversion to the GIS database in batches, that is, store the first monitoring data of the set data size each time. For example, the set data amount may be 500 pieces, 1000 pieces, and the like, which is not limited in this embodiment of the present invention.
In an optional implementation manner, the synchronization progress information may also be displayed, so that the user can know the synchronization progress more intuitively. Therefore, after the GIS platform stores the first monitoring data of one batch after format conversion every time, the GIS platform determines the current synchronization progress information and displays the synchronization progress information in a popup window.
For example, the GIS platform may obtain the total data volume of the first monitoring data, and after storing the first monitoring data of one batch each time, may calculate the percentage of the currently stored data volume in the total data volume, and use the percentage as the current synchronization progress information.
The webSocket of the GIS server can be connected with the webSocket of the GIS client, so that after the GIS server determines the current synchronization progress information, the webSocket of the GIS server can be triggered to send the synchronization progress information to the webSocket of the GIS client, the GIS client performs popup window display on the synchronization progress information, and the currently stored data volume can be displayed.
If the paging synchronization mode is adopted, the video network monitoring and scheduling platform returns the first monitoring data based on the internet protocol of the paging data volume to the GIS platform according to the monitoring synchronization request after receiving the monitoring synchronization request. The GIS platform converts the format of the first monitoring data based on the internet protocol of the paging data volume into a format supported by the GIS platform. And the GIS platform stores the first monitoring data of the paging data volume after format conversion in batches.
And after the GIS platform stores the first monitoring data after the format conversion of the paging data volume, sending a completion notice to the video networking monitoring and scheduling platform. And after receiving the completion notice, the video networking monitoring and scheduling platform returns the first monitoring data based on the internet protocol of the next paging data volume to the GIS platform. And the GIS platform receives first monitoring data of the paging data volume, which is returned by the video networking monitoring and scheduling platform aiming at the completion notice and is based on the Internet protocol, converts the format of the first monitoring data of the paging data volume, which is based on the Internet protocol, into a format supported by the GIS platform, and stores the first monitoring data of the paging data volume after format conversion in batches. And then, continuing to circulate until all the first monitoring data are synchronously completed.
