Abstract

The invention belongs to the technical field of computer networks, and discloses a balancing method and system for improving the survivability of P2P data storage. The method includes the steps of carrying out a distribution mechanism for mapping the IP addresses of participating nodes into data of a linear space through the hash function, segmenting the space according to replication factors, carrying out query and consistency maintenance mechanism to determine the nearest region containing a copy node according to the key value of a request node, and determining a basic consistency maintenance strategy and a periodical consistency maintenance strategy by a routing protocol in a given DHT system. The performance evaluation indexes are divided into dynamic and static performance indexes for the first time, the evaluation of the algorithm is more comprehensive and accurate, and the method can be applied to systems with different scales. Meanwhile, the algorithm can be used in protocolsof different DHT systems, that is a user interface corresponding to the system applying the algorithm can be based on different protocols, and management and maintenance are facilitated.

Description

technical field

[0001] The invention belongs to the technical field of computer networks, and in particular relates to an equalization method and system for improving the invulnerability of P2P data storage. Background technique

[0002] At present, the existing technologies commonly used in the industry are as follows:

[0003] 1. With the rapid development of computer networks and the rapid popularity of office automation, data storage has received more and more attention. However, P2P systems have been extensively analyzed in recent years due to their good performance (distribution, scalability). The phenomenon of data availability performance degradation caused by the dynamic nature of P2P systems (which is related to the frequent joining, leaving or failure of participating nodes in the system) is one of the challenges in the design of data storage strategies for P2P systems. One of the ways to improve system fault tolerance under high loss rate is to design a better...
