The existing Internet of Things is mainly based on IPV4 communication. Due to the scarcity of IPV4 address resources, it is difficult for most devices to obtain public network IP. The point-to-point communication between devices on different network segments on the Internet needs to go through the public network server, which further increases the concurrent pressure and security of the server. risk

Embodiment 1
[0044] Assuming that the national share of a car is 10 million, a built-in APP software in the car needs to be updated.
[0045] 1. Automobile factories, 4S stores and all automobiles are connected to the Internet and use the IPV6 communication protocol.
[0046] 2. The internal equipment of the automobile factory is used as a micro-service node, and all cars are registered with the service node when they are sold.
[0047] 3. Microservice nodes establish 4S stores and registered car routing tables. The microservice node sends the update package and the routing package to two groups of 10 adjacent nodes, that is, 10 4S stores, and the 10 4S stores send it to 100 4S stores. After 3 times of forwarding, 1000 4S stores receive it. A 4S store forwarded it to 10 local cars, and a total of 10,000 cars across the country received it;
[0048] 4. Take car A as an example. After receiving the forwarding packet, verify the MD5 and send a feedback packet to the upper-level 4S store con...
Embodiment 2
[0054] 1. Take the assembly line online detection equipment used in the factory as an example. After the equipment is installed, manual on-site testing, manual adjustment, and product parameter learning and storage are required.
[0055] 2. All devices are connected to the Internet and use the IPV6 communication protocol.
[0056] 3. Establish several devices as index service nodes to form an index service circle.
[0057] 4. An experienced installer from a certain factory registers with the index circle for the "product parameter learning" service after successful installation and testing of the equipment.
[0058] 5. After a certain factory equipment X has been running for a period of time, due to the replacement of assembly line products or improper parameters and equipment of factory personnel, the detection accuracy of the equipment decreases. Because the factory is located in a backward country, local maintenance personnel cannot solve the problem.
[0059] 6. X search...

Abstract
The invention discloses a decentralized Internet of Things micro-service subscription and push method, by establishing a plurality of initial index service nodes that provide index services publicly through IP; by establishing nodes that can provide index services, and sending any initial index service The node SSi registers, and the initial index service node forms an index service circle I; through any node Cj that needs to serve, a search request is made to any node Ii in the index service circle, and any node Ii provides a mapping relationship record index directory to The node Cj that needs the service, the node Cj that needs the service selects the service node Sk from it according to its own algorithm, and registers with the service node Sk, and applies for the subscription service; using any node as the service node, it can be achieved with a geometric progression With message push, any node can provide large-scale microservices without the need for a central node.
Description
technical field [0001] The invention belongs to the Internet, and in particular relates to a method for subscribing and pushing decentralized Internet of Things microservices. Background technique [0002] The Internet of Things (IoT, Internet of things) is the "Internet that connects everything". , Internet of things network. In order to manage a huge number of IoT devices, the industry has proposed a variety of IoT real-time protocols, such as XMPP, CoAP, and MQTT. These protocols are all based on the "server-client" mechanism. When there are a large number of devices, the concurrent pressure on the server is very high, and the IP address of the server is fixed, which is vulnerable to attack. The existing Internet of Things is mainly based on IPV4 communication. Due to the scarcity of IPV4 address resources, it is difficult for most devices to obtain public network IP. The point-to-point communication between devices on different network segments on the Internet needs to...
