Problems solved by technology

Compared with the Client / Server computing model, P2P has many advantages. At present, there are mainly two kinds of P2P networks in the world. One is the unstructured P2P network, which uses the flooding protocol to discover nodes. The second is a structured P2P network, which uses DHT to map content and nodes to a globally unique identifier in the same format. The disadvantage is that the semantics of nodes and content itself are broken by the hash function
Due to the lack of node semantics, it is difficult for large-scale enterprises to cooperate with each other using information technology

Embodiment 1

[0071] Construct the vertical virtual network of enterprises involved in the supply chain of vaccine pharmaceutical factories:

[0072] The companies involved in the supply chain of vaccine pharmaceutical factories are classified according to the International Standard Industrial Classification of All Economic Activities (ISIC). For example: a factory producing hepatitis A vaccine belongs to "Enterprise. Manufacturing. Drugs and pharmaceutical chemicals. Drugs. Vaccines". Eggs are used as raw materials in the production of hepatitis A vaccine, and egg production enterprises are classified as "enterprises. Agriculture and animal husbandry. Livestock products". Packaging materials include paper boxes, etc. Paper box production enterprises belong to "Enterprise.Manufacturing.Papermaking and paper products.Paper containers". Hepatitis A vaccine wholesale enterprises belong to "Enterprise. Wholesale. Western Medicine Wholesale". according to figure 2 , these vertical virtual or...

example 1

[0087] Example 1: Vaccine pharmaceutical factory A has produced a new batch of high-quality hepatitis A vaccine and wishes to notify interested vaccine wholesale companies. according to Figure 4 , the action message sent by Vaccine Pharmaceutical Factory A includes an action statement written in a custom language, and its format is:

[0088] Act actscripts On domainref [WHERE search_condition];

[0089] Among them, Act is an action predicate, actscripts is an action specification, domainref is a virtual group domain name, and search_condition is a conditional expression in an SQL language query statement.

[0090] Action statement written by Vaccine Pharmaceutical Factory A: Advocate noticeContext On Enterprise.Wholesale.Western Medicine Wholesale where prod="HAVvaccine";

[0091] Advocate is the broadcast action; noticeContext is the notification content; enterprise.wholesale.western medicine wholesale is the virtual group of the notification; the notified product involves...

example 2

[0094] Example 2: Vaccine pharmaceutical factory A invites bids for the raw material for the production of Type A vaccine -- eggs, and hopes to invite bids for all eggs. according to Figure 4 , the action message sent by Vaccine Pharmaceutical Factory A, including the written action statement: Bid lowestPrice 0nEnterprise. Agriculture and Animal Husbandry. Livestock products where prod="bird eggs" and schedule="2009-08-20" and quality="best" and amount="10000"; the meaning of the sentence is to bid for 10,000 best eggs at the lowest price from all egg factories in the enterprise.agriculture.livestock product virtual group, which must meet the 2009-08-20 delivery conditions.

[0095] The current routing table of node A of vaccine pharmaceutical factory includes node B of paper packaging factory (paper packaging factory B@enterprise.manufacturing.papermaking and paper products.paper container, IP address: 12.89.6.15) and cached node A of vaccine wholesale company (vaccine Whol...

Abstract

The invention relates to a method for constructing a P2P network for a vertical virtual group, comprising a step of industry-to-enterprise classification, a step of constructing a semanteme P2P network of the vertical virtual group and a step of action actualization in a distributing mode, wherein the step of industry-to-enterprise classification is to classify products or services provided by the enterprise into various vertical organizations according to classification methods. Compared with the prior art, the invention has the advantages that the method classifies all the enterprises according to a certain classification standard to form a classified enterprise tree, each path on the tree forms a vertical virtual organization, each enterprise belongs to one or more vertical virtual organization, and all the vertical virtual organizations form a global enterprise virtual organization; the enterprises are classified according to types thereof to join into corresponding virtual organizations, and all the enterprises in the world join into corresponding vertical virtual organizations according to the classification standard so as to join together; and every two enterprises can conveniently cooperate with each other by utilizing the large virtual organization.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a method for constructing a P2P network of a network vertical virtual group. Background technique [0002] As more and more enterprises deploy enterprise management systems and web servers connected to the Internet, the use of IT technology for inter-enterprise cooperation is gradually being recognized by the business community and academia. At present, most enterprises use IT technology to conduct price discovery, purchase, payment, etc. through the client / server model platform. However, if enterprises adopt IT technology for inter-enterprise cooperation covering the entire supply chain, the client / server model will encounter some problems. Supply chains involve many different types of businesses, most of which are small and medium-sized businesses. There are a large number of small and medium-sized enterprises, and the data format is inconsistent and lacks docume...
