Detailed ways

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

The Internet of Vision is an important milestone in the development of the network. 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.

The Internet of View adopts real-time high-definition video exchange technology, which can provide required services on one network platform, such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, time-lapse TV, online teaching, live broadcast , VOD on demand, TV mail, personalized recording (PVR), intranet (self-managed) channel, intelligent video broadcast control, information release and other dozens of video, voice, picture, text, communication, data and other services are all integrated in one System platform, realize high-definition quality video playback through TV or computer.

In order to enable those skilled in the art to better understand the embodiments of the present invention, the Internet of Things is introduced as follows:

Some of the technologies applied in the Internet of Things are as follows:

Network Technology

The network technology innovation of the Internet of View has improved 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), video networking technology uses Packet Switching to meet Streaming requirements. The Internet of Vision 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, realizing the seamless connection of switched virtual circuits and data protocols throughout the network.

Switching Technology

Video networking adopts the two advantages of Ethernet asynchronous and packet switching, eliminates the defects of Ethernet under the premise of full compatibility, has end-to-end seamless connection of the whole network, directly connects to user terminals, and directly carries IP data packets. User data does not require any protocol conversion within the entire network. Video networking is a more advanced form of Ethernet. It is a real-time switching platform, which can realize the real-time transmission of large-scale high-definition video in the whole network that cannot be realized by the Internet at present, and push many network video applications to high-definition and unification.

Server Technology

The server technology on the Internet of View and unified video platform 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 streaming and unified video platform streaming media processing is much simpler than data processing, and the efficiency is greatly improved by more than 100 times compared with traditional servers.

Storage Technology

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

Network Security Technology

The structural design of the Internet of View completely eradicates the network security problems that plague the Internet through the individual licensing system for each service, complete isolation of equipment and user data, and generally does not require anti-virus programs and firewalls, preventing hackers and virus attacks , to provide users with a structured worry-free security network.

Service Innovation Technology

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

The networking of the Internet of View is as follows:

Vision networking is a network structure with centralized control. The network can be a tree network, star network, 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, terminal (including various set-top boxes, encoding boards, storage, etc.). The node server is connected with the access switch, and the access switch can be connected with multiple terminals and can be connected with Ethernet.

Wherein, the node server is a node with centralized control function in the access network, which can control the access switches and terminals. The node server can be directly connected to the access switch, and can also be directly connected to the terminal.

Similarly, the devices in the MAN part can also be divided into three categories: MAN servers, node switches, and node servers. The metro server is connected to the node switch, and the node switch can be connected to multiple node servers.

Wherein, 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 a centralized control function in the metropolitan area network, which can control node switches and node servers. The metro server can be directly connected to the node switch, or directly connected to the node server.

It can be seen that the entire Vision Network is a layered centralized control network structure, while the network controlled by the node server and the metro server can be in various structures such as tree, star, and ring.

Vividly speaking, the access network part can form a unified video platform (the part in the dotted circle), and multiple unified video platforms can form a video network; each unified video platform can be interconnected through the metropolitan area and the wide area video network.

Classification of Internet of Things devices

1.1 The devices in the Internet of View in the embodiment of the present invention can be mainly divided into three categories: servers, switches (including Ethernet gateways), terminals (including various set-top boxes, encoding boards, memory, etc.). As a whole, the Internet of Things can be divided into a metropolitan area network (or a national network, a global network, etc.) and an access network.

2. Definition of Internet of Vision data packets

2.1 Definition of access network data packet

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 data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are up to 256 possibilities, The second byte to the sixth byte are the addresses of the metropolitan area network, and the seventh and eighth bytes are the addresses of the access network;

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

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

2.2 MAN packet definition

The topology of the metropolitan area network is a graph. There may be two or even more than two types of connections between two devices, that is, there may be more than 2 connections between node switches and node servers, node switches and node switches, and node switches and node servers. kind of connection. However, the MAN address of the MAN device is unique. In order to accurately describe the connection relationship between MAN devices, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a MAN device.

The definition of labels in this manual is similar to the definition of labels in MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switching). Assuming that there are two connections between device A and device B, then the data packets from device A to device B have 2 labels, the packet from device B to device A also has 2 labels. The label is divided into an incoming label and an outgoing label. 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 all dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label allocation, MPLS label allocation is the result of mutual negotiation between switches and servers.

As shown in the table below, the data packet of the MAN mainly includes the following parts:

DA SA Reserved Label Payload CRC

That is, destination address (DA), source address (SA), reserved byte (Reserved), label, payload (PDU), and CRC. Among them, the label protocol can refer to the following definition: the label is 32bit, of which the high 16bit is reserved, and only the low 16bit is used, and its position is between the reserved byte of the data packet and the payload.

Based on the above characteristics of the Internet of Vision, one of the core ideas of the embodiments of the present invention is proposed.
