Problems solved by technology

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]A car nation has a total of 10 million units, and an APP software built into a car needs to be updated.

[0045]1. Automobile manufacturing plant, 4S shop and all car are connected to the Internet, using IPv6 communication protocols.

[0046]2. The internal equipment of the automobile manufacturing plant is used as a micro-service node, and all car is sold to the service node.

[0047]3, the micro service node establishes 4S shop and the registered car routing table. The micro-service node will update the package and routing to the two groups of 10 nodes, 10 4S shops, 10 4S shops send 100 4S shops, three times forward, 1000 4S shop received. A 4S shop forwarded to the local 10 cars, a total of 10,000 cars received;

[0048]4, take the car A as an example, after receiving the forwarding package, verify the MD5, send the feedback package to the upper 4S shop connected to it, 4S shop will retransmit a number of times if it does not receive the feedback package or MD5 verification, will reach...

Embodiment 2

[0054]1. Taking the line detection equipment used in the factory as an example. This device is installed after installation, manually adjustment, product parameters learn and save.

[0055]2. All devices are connected to the Internet and use the IPv6 communication protocol.

[0056]3. Establish several devices as the index service node to form an index service circle.

[0057]4. After an experienced installation test of a factory is successful, register "Product Parameters" service to the index circle.

[0058]5, a factory device X runs for a while, due to improper delivery of the pipeline product replacement or factory personnel parameter equipment, the equipment detection accuracy is lowered. Due to the fact that the plant is in a backward country area, local maintenance personnel cannot solve.

[0059]6, X Search "Product Parameter Learning" service to the index service node.

[0060]7, the index service node sends a machine directory that can provide product parameters learning services to X.

[006...

Abstract

The invention discloses a decentralized IOT micro-service subscription and push method. The method comprises the following steps: establishing a plurality of initial index service nodes which are disclosed by an IP and provide index service; establishing a node capable of providing an index service, registering to any initial index service node SSi, and forming an index service circle I by the initial index service node; enabling a search request to be put forward to any node Ii in an index service circle through any node Cj needing to be served, wherein any node Ii provides a mapping relation record index directory to the node Cj needing to be served according to an association algorithm of the node Ii, and the node Cj needing to be served selects a service node node Sk according to the algorithm of the node Cj needing to be served and registers and applies for subscription service to the service node node Sk; and adopting any node as a service node, so that message pushing can be achieved through speed increase of geometric progression, any node can provide large-scale micro-services, and a center node is not needed.

Description

Technical field[0001]The present invention belongs to the Internet, and more particularly to a detrimental IoT micro service subscription and push method.Background technique[0002]IoT, Internet of Things, "Internet connected to the Internet", is extended and expanded based on the Internet, combining various information sensing devices, achieving any time, any location, people, machine Network interoperability interoperability. For the huge Internet of Thining Internet of Things, the industry has proposed a variety of Internet of Internet real-time protocols, such as XMPP, COAP, and MQTT. These protocols are based on the "Server-Client" mechanism. When the number of devices is large, the server is very pressing, and the server IP address is fixed and vulnerable. The existing Internet of Things is based primarily based on IPv4 communication. Since IPv4's address resource is scarce, most devices are difficult to obtain public network IP, and devices on different network segments on the...
