Problems solved by technology

[0008] The present invention analyzes the bottleneck problem existing in the current EPC-ONS, which may even lead to problems such as large query delay, low query efficiency, and single-point failure. Even if the single / multi-layer DHT-ONS naming analysis system reflects the topology structure, it cannot match the actual The combination of physical topology reduces the efficiency of analysis data return

Embodiment Construction

[0040] The specific query and analysis process of the present invention adopts a bottom-up approach, and the specific process is as follows Figure 4 Shown:

[0041] A. Host T 0 Issue a get(X) request with Hash(ID of object X)=K 1 As a keyword for query analysis;

[0042] B. Host T 0 with the nearest access point AN A Connect with keyword K 1 Start at access point AN A Perform query analysis in the DHT domain;

[0043] C. Query judgment AN A Whether there is K stored in the DHT domain 1 Relevant information of , that is, DR (record dictionary item), if there is, then go to H; if not, just go to G;

[0044] D. Query to determine whether K is stored in the DHT domain of this level 1 The relevant information of , that is, DR (record dictionary item), if there is, then go to H; if not, then go to E;

[0045] E. Determine whether the layer has reached the highest level, that is, the DHT domain at the top AS level. If it is the highest level, go to F; if it is not the hi...

Abstract

The invention provides a discrete hadamard transform (DHT) analyzing system based on physical topology, which adopts design concept of well combining logic network of DHT with actual physical network. The system can not only effectively resolve the problems of low delay, imbalanced load and efficiency of an object name service (ONS) analyzing system through a three-dimensional and topologized embedding structure, but also resolves the problem that data passing-back efficiency in a current analyzing system is low through a comprehensive physical network topological structure of a reaction bottom layer, thereby ensuring routing localization of the network and improving analyzing efficiency of the Internet of things. Besides, the system can further provide a uniform analyzing framework for three-dimensional and planarity naming space and resolve the problem that current analyzing systems cannot correctly analyze non-layered naming spaces.

Description

technical field [0001] The physical entity connection network is an intelligent network system that uses data acquisition technology and sensing technology to connect items to the network in accordance with standardized protocols, so as to realize the identification, positioning, tracking, monitoring and management of items. As an important part of the new generation of network technology, the physical entity connection network needs to realize the positioning and analysis of global items through a complete set of mechanisms, and this set of mechanisms should have good openness and scalability. The core of the naming analysis mechanism is how to match the object code with the corresponding object information, that is, how to convert the object ID into an IP address that the network can recognize by analyzing the object ID, so that the network "knows" the item. The naming analysis method can be used as an automatic network service system, similar to DNS (Domain Name Analysis Se...
