Description

Intent-oriented OSI seven-layer network protocol model based on data, information and knowledge objects

Technical Field

The present invention relates generally to data communication over computer networks and computer protocols that facilitate such communication. More particularly, the present invention relates to an object oriented communication interface for network protocol access.

Background

Early in the computing industry, computer systems were stand-alone processors to which peripheral devices (e.g., displays, printers, and input devices) had been connected. Each computer system is independent and there is little communication between the computer systems. Today, it is well known to interconnect computer systems in a computer network, such as a local or wide area network, to achieve a variety of benefits, including sharing data, information, and knowledge available from the various computer systems coupled to the network.

Many communication protocols have been developed for communicating between different computer systems along a network, and some examples of well-known network protocols include the System Network Architecture (SNA), the transmission control protocol/Internet protocol (TCP/IP), the network basic input output system (NetBIOS), and the Internet packet exchange/sequential packet exchange (IPX/SPX). Other communication protocols are known and widely used and described in various standards of ISO, IEEE, and other organizations. To facilitate an understanding of computer networks, network functions and associated software are often described as a series of layers. Data transfer between one copy of the distributed application program and another copy of the distributed application program over the network is possible through the use of services of the underlying communication layer family. Typically, each layer in a computer system has a corresponding layer in the receiving computer system, such that each layer communicates with a corresponding peer layer.

Disclosure of Invention

Technical problem

The existing communication protocol can be regarded as that a transmission object is unpacked from the top layer (application layer) step by step through each layer, then is transmitted through the bottom layer, and then the process of adding packets step by step does not make fundamental changes to the problems of the format of transmission content and the like. How to make the receiver receive the information quickly is an important problem, that is, when the transmission content is a large file, the receiver can receive the content to be expressed by the transmitter in a short time.

Technical scheme

In view of the above problems, the present application relates to an intention-oriented OSI seven-layer network protocol model based on data, information and knowledge objects, which is characterized in that a transmission object is converted to a data map, an information map and a knowledge map, and the substantive content of the transmission is judged for the purpose of a transmitter. By using the data as an initial value and using a value-added seven-layer protocol imitating OSI, the purpose of improving the interaction efficiency among network personnel is achieved, and the risk of privacy disclosure in the transmission process is greatly reduced.

Architecture

The invention relates to an intention-oriented OSI seven-layer network protocol model based on data, information and knowledge objects, which is characterized in that a transmission object is converted to a data map, an information map and a knowledge map, and the substantive content of the transmitted content is judged according to the purpose of a transmitter. The aim of improving the interaction efficiency among network personnel is achieved by using a seven-layer protocol imitating OSI, wherein data is used as an initial value and the aim of increasing value.

The invention defines data and data map, information and information map and knowledge map as follows:

data mapping: data are the basic individual items of numeric or other types of information that are obtained by observation, but without context they have no meaning in themselves. The data map can be expressed by data structures such as arrays, linked lists, queues, trees, stacks, graphs and the like. On a data map, the support degree and the confidence degree of the data on the data map are obtained by calculating the frequency of the data to delete wrong or useless data, the deleting condition is that the threshold requirements of the support degree and the confidence degree must be met at the same time, the overlarge threshold value is not beneficial to the accurate expression of the map, the undersize threshold value is not beneficial to the integrity of the expression, and the dynamic adjustment can be carried out according to the result information fed back by the calculation map.

An information map: the information is conveyed by context after data and data combination, and is properly analyzed and interpreted after concept mapping and correlation combination. The information map may be expressed by a relational database. And (3) performing data cleaning on the information map, eliminating redundant data, performing preliminary abstraction according to interaction between nodes, and improving the design cohesion. By delineating a specific number of entities, calculating an internal interaction degree and an external interaction degree, the cohesiveness is equal to the ratio of the internal interaction degree to the external interaction degree, and the invention sets that the delineated knowledge points must be interconnected.

Knowledge graph: knowledge is the overall understanding and awareness obtained from the accumulated information, and a knowledge graph may be expressed by a directed graph containing nodes and relationships between nodes. The knowledge graph can contain various semantic relations and can carry out information reasoning and entity linking, and the unstructured characteristic of the knowledge graph enables the knowledge graph to be seamlessly connected, so that the edge density and the node density of the knowledge graph are improved. Information reasoning needs to be supported by relevant relation rules, which can be manually constructed by people, but are time-consuming and labor-consuming. Currently, it relies primarily on the co-occurrence of relationships and uses associative mining techniques to automatically find inference rules. The path recommendation algorithm extracts relationships by constructing a large number of relationship paths in a knowledge graph to construct a relationship-classified feature vector and a relationship classifier using each different relationship path as a one-dimensional feature.

Advantageous effects

The invention has the following beneficial effects:

(1) according to the invention, the transmission content is modeled, so that the transmission loss is reduced, and the communication efficiency is improved;

(2) the invention models the transmission content to the data, information and knowledge level, thus improving the privacy protection degree;

(3) the invention supplements the existing network protocol rules and has certain market application value.

Detailed Description

The invention relates to an intention-oriented OSI seven-layer network protocol model based on data, information and knowledge objects, which comprises the following concrete implementation steps:

step 1) a transmitter inputs transmission contents such as sound, pictures, characters or videos, the model carries out modeling according to a transmission intention to analyze a transmission object, extracts entities in the transmission object, namely data, and constructs a data map; then extracting the relation between the entities in the transmission object, wherein the relation comprises a path, an attribute, a logic relation, a causal relation and the like, and constructing an information map; and finally, constructing the knowledge graph through inductive summarization and logical reasoning. When the image is transmitted as a picture as shown in fig. 1, the entities, i.e. wild goose, sun and sea surface, in the image are extracted by analyzing the information in the image. Then extracting the relationship of the three entities, namely the wild goose is at the left of the sun, above the sea surface and the like (specifically, pixel points, angles, distances and the like); in this transmitted picture, no knowledge graph needs to be constructed, so the transmission object may not include a knowledge graph when mapped on the graph.

And 2) transmitting the data map, the information map and the knowledge map obtained in the step 1) on different layers, wherein the structure of each layer is defined to be a form of P + G, wherein P represents a target, and G represents a map, which is different from an OSI seven-layer protocol. The specific format of each layer is as follows:

1) an application layer:

2) presentation layer:

3) and a session layer:

4) a transmission layer:

5) network layer:

6) data link layer:

7) physical layer:

。

and 3) unpacking the data map at the receiving end, namely converting the data map, the information map and the knowledge map into the original content transmitted at the output end again.
