Problems solved by technology

[0004] However, there is a problem of how to ensure data consistency in a distributed structured network: when a resource shared by a node changes, due to the lack of a central server, how does this node quickly notify other nodes, including downloading and using the resource It is a problem worth studying to update the resources in time so that they can enjoy the latest services

Embodiment Construction

[0030] 1. Architecture

[0031]The technical solution for P2P data consistency maintenance proposed by the present invention has a network topological structure that is divided into a network structure of many small areas. That is, the entire large network is divided into many small areas, and each area independently completes the tasks of receiving messages, disseminating messages within the domain, and delivering messages to other domains. Firstly, the node that initiates the resource change notifies other nodes in its domain. After receiving the message, each node in the domain notifies its adjacent domains, and other domains transmit messages to further domains. Through the work of each domain, it is finally possible to send messages to the entire network, and then notify the nodes in the network to update resources.

[0032] figure 1 The system framework of the scheme is given: node domain (Area), as the most important concept in this scheme, is the basis for completing...

Abstract

The invention provides a technical method of maintaining data consistency in distributed structured P2P (Peer-to-peer equal compute technology) network based on the method of maintaining data consistency in regional equal compute in distributed Hash tables, establishes framework model based on Kademlia (one of distributed Hash tables) routing algorithm, divides the system into small areas and adopts divide-and-conquer method. The invention provides a network structure based on Kademlia routing algorithm and blocked area, which solves the problem that in large scale P2P network, how to rapidly and efficiently notify the resource updating message to the node in network; compared with the traditional method, the method has distribution, efficiency and scalability.

Description

technical field [0001] The present invention proposes a technical method for data consistency maintenance in a distributed structured P2P (peer-to-peer computing technology) network, establishes a framework model based on Kademlia (a kind of distributed hash table) routing algorithm, and divides the system into The small area adopts the idea of ​​divide and conquer and belongs to the field of distributed computing technology. Background technique [0002] Peer-to-Peer Computing (P2P) changes the original asymmetric computing mode such as C / S computing (Client / Server Computing) or B / S computing (Brower / Server Computing). Etc., can be both a user and a provider of services, which provides a flexible and scalable computing platform for large-scale information sharing, direct communication and collaborative work. At present, P2P technology is mainly applied to the following fields: P2P network providing file and other content sharing, collaborative processing and service sharin...
