Novel service-oriented internet of things system structure

Abstract

The invention provides a novel service-oriented internet of things system structure. A basic data structure of the network comprises seven tuples, namely application layer data, a source device identifier, a destination device identifier, a source service ID, a destination service ID, a source address identifier and a destination address identifier. A data packet is routed in a network through anaddress symbol and a service ID to realize service-to-service communication, a destination address symbol firstly sends a service request to a network device closest to a destination service ID, and then the network device sends the service request to a corresponding service process according to the destination service ID. The network architecture not only can be constructed independently, but also can be compatible with an existing TCP / IP network. According to the structure disclsosed in the invention, the service is taken as an object, the target of finding the service by the service is realized, the data structure of the routing protocol is reconstructed, the full separation of the equipment, the service and the address is realized, the security of the system is improved, and the identity and the attribute of the service carried by the equipment cannot be misjudged after the equipment moves.

Description

technical field [0001] The invention belongs to the field of computer network architecture and relates to a new service-oriented Internet of Things architecture. Background technique [0002] The traditional Internet of Things architecture uses the traditional Internet as the bearer network to realize functions such as data collection and transmission of terminal equipment, and end-to-end communication. The traditional IoT architecture is an end-to-end or end-to-server communication mode, but for the user, what he cares about is not the terminal device or network device, but how to respond to his service request, as for who will do it Responses, for the user, don't care about the content. At the same time, the binding of device identity and address results in poor mobility of devices or networks. These problems make the existing Internet of Things architecture unable to meet the needs of the Internet of Things for scalability, dynamic update, management control, device mob...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the existing new network architecture either cannot be "service-centric", or cannot solve the problem of "device mobility"
