Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Video networking is an important milestone in network development. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.

Video networking adopts real-time high-definition video switching technology, which can combine the required services on a network system, such as high-definition video conference, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, delayed TV, network teaching, live broadcast , VOD on demand, TV mail, personal recording (PVR), intranet (self-organized) channels, intelligent video broadcast control, information release and other dozens of video, voice, picture, text, communication, data and other services are all integrated into one system to achieve high-definition video playback through a TV or computer.

In order to make those skilled in the art better understand the embodiments of the present invention, video networking is introduced as follows:

Some of the technologies applied by the Internet of Views are as follows:

Network Technology

The network technology innovation of the video network improves the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Different from pure network packet switching (Packet Switching) or network circuit switching (Circuit Switching), the Internet of View technology adopts Packet Switching to meet the requirements of Streaming. The Internet of Things technology has the flexibility, simplicity and low price of packet switching, and at the same time has the quality and security assurance of circuit switching, and realizes the entire network of switched virtual circuits and seamless connection of data formats.

Switching Technology

The Internet of Things adopts the asynchronous and packet switching advantages of Ethernet, and eliminates the defects of Ethernet under the premise of full compatibility. User data does not need any format conversion in the whole network. Video networking is a more advanced form of Ethernet. It is a real-time switching system that can realize the real-time transmission of large-scale high-definition video across the entire network that cannot be achieved by the Internet, and push many network video applications to high-definition and unified.

Server Technology

The server technology on the Internet of View and unified video system is different from the server in the traditional sense. Its streaming media transmission is based on connection-oriented, and its data processing capability has nothing to do with traffic and communication time. A single network layer can contain information. command and data transmission. For voice and video services, the complexity of video networking and unified video system streaming media processing is much simpler than data processing, and the efficiency is greatly improved by more than 100 times compared to traditional servers.

Storage Technology

The ultra-high-speed storage technology of the unified video system adopts the most advanced real-time operating system in order to adapt to the media content of large capacity and large flow, and maps the program information in the server instruction to the specific hard disk space, and the media content no longer passes through the server. It is directly delivered to the user terminal in an instant, and the general waiting time of the user is less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical movement of the hard disk head seeking, and the resource consumption only accounts for 20% of the same level of IP Internet, but it generates 3 times more concurrent traffic than traditional hard disk arrays, and the overall efficiency is increased by more than 10 times.

Network Security Technology

The structural design of the Internet of Things completely eliminates the network security problems that plague the Internet through separate licensing for each service and complete isolation of equipment and user data. Generally, anti-virus programs and firewalls are not required, and hackers and viruses are prevented from attacking. , to provide users with a structured worry-free safety network.

Service Innovation Technology

The unified video system integrates services and transmission. Whether it is a single user, a private network user, or a network aggregate, it is just an automatic connection. User terminals, set-top boxes or PCs are directly connected to the unified video system to obtain a variety of multimedia video services in various forms. The unified video system adopts the "recipe-style" table matching mode to replace the traditional complex application programming, which can realize complex applications with very little code, and realize "unlimited" new business innovation.

The networking of the Internet of Things is as follows:

The Internet of Things is a centralized control network structure. The network can be a tree network, a star network, a ring network, etc., but on this basis, a centralized control node is required in the network to control the entire network.

As shown in Figure 1, the Internet of Things is divided into two parts: the access network and the metropolitan area network.

The equipment in the access network part can be mainly divided into three categories: node server, access switch, and terminal (including various set-top boxes, coding boards, memory, etc.). The node server is connected to the access switch, and the access switch can be connected to multiple terminals and can be connected to Ethernet.

The node server is a node in the access network that functions as a centralized control, and can control access switches and terminals. The node server can be directly connected to the access switch, or it can be directly connected to the terminal.

Similarly, the equipment in the metropolitan area network can also be divided into three categories: metropolitan area server, node switch, and node server. The metropolitan area server is connected with the node switch, and the node switch can be connected with multiple node servers.

The node server is the node server of the access network part, that is, the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node with centralized control function in the metropolitan area network, which can control the node switch and the node server. The metropolitan area server can be directly connected to the node switch or directly connected to the node server.

It can be seen that the entire VisionLink network is a network structure controlled by layers and centralized, and the network controlled by the node server and the metro server can be tree, star, ring and other structures.

Figuratively, the access network part can form a unified video system (the part in the dotted circle), and multiple unified video systems can form a video network; each unified video system can be interconnected through the metro and wide-area video networks.

Classification of Internet-connected devices

1.1 The devices in the video networking according to the embodiment of the present invention can be mainly divided into three categories: servers, switches (including Ethernet protocol conversion gateways), and terminals (including various set-top boxes, coding boards, memories, etc.). As a whole, the Internet of Views can be divided into a metropolitan area network (or a national network, a global network, etc.) and an access network.

1.2 The equipment in the access network part can be mainly divided into three categories: node server, access switch (including Ethernet protocol conversion gateway), terminal (including various set-top boxes, coding boards, memory, etc.).

2. Definition of Internet Data Packets

2.1 Definition of Access Network Data Packets

The data packet of the access network mainly includes the following parts: destination address (DA), source address (SA), reserved bytes, payload (PDU), and CRC.

As shown in the table below, the data packets of the access network mainly include the following parts:

DA SA Reserved Payload CRC

in:

The destination address (DA) consists of 8 bytes (byte), the first byte indicates the type of the data packet (such as various data packets, multicast data packets, unicast data packets, etc.), there are up to 256 possibilities, The second to sixth bytes are the metropolitan area network address, and the seventh and eighth bytes are the access network address;

The source address (SA) is also composed of 8 bytes (byte), and the definition is the same as the destination address (DA);

Reserved bytes consist of 2 bytes;

The payload part has different lengths according to different datagram types. If it is a variety of data packets, it is 64 bytes. If it is a single multicast data packet, it is 32+1024=1056 bytes. Of course, it is not limited to Above 2 kinds;

The CRC consists of 4 bytes, and its calculation method follows the standard Ethernet CRC algorithm.

2.2 MAN Data Packet Definition

The topology of the metropolitan area network is a graph. There may be two or even more than two connections between two devices, that is, there may be more than two connections between node switches and node servers, between node switches and node switches, and between node switches and node servers. kind of connection. However, the metropolitan area network address of the metropolitan area network equipment is unique. In order to accurately describe the connection relationship between the metropolitan area network equipment, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a metropolitan area network equipment.

The definition of labels in this specification is similar to the definition of MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switch) labels. Assuming that there are two connections between device A and device B, the data packets from device A to device B have 2 labels, packets from device B to device A also have 2 labels. Labels are divided into incoming labels and outgoing labels. Assuming that the label (incoming label) of the data packet entering device A is 0x0000, the label (outgoing label) of the data packet when it leaves device A may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, which means that the address allocation and label allocation of the metropolitan area network are dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label assignment, MPLS label assignment is the result of mutual negotiation between switches and servers.

As shown in the table below, the data packets of the metropolitan area network mainly include the following parts:

DA SA Reserved Label Payload CRC

Namely destination address (DA), source address (SA), reserved bytes (Reserved), label, payload (PDU), CRC. Among them, the format of the label can refer to the following definition: the label is 32 bits, of which the upper 16 bits are reserved, and only the lower 16 bits are used, and its position is between the reserved bytes of the data packet and the payload.

Based on the above characteristics of the video network, one of the core concepts of the embodiment of the present invention is proposed. The image transmission server is used as a bridge between the video network server and the video network terminal in the mobile command vehicle, so that the video network server can use the image transmission server. The video network data packet is transmitted to the video network terminal in the mobile command vehicle, so that the video network terminal can be directly applied to the mobile command vehicle.

The image transmission server can serve multiple mobile command vehicles, and the device information corresponding to different mobile command vehicles is different. The server determines which mobile command vehicle the video network data packet needs to be transmitted to.

Step 606, when the target device information matches the target device information in the device information, the Internet of View data packet is transmitted to the mobile network card corresponding to the target device information through the mobile network link based on the network protocol IP.
