Protection Strategies in Peer-To-Peer Networks File Duplication and Regularity

Duplication is used to increase data availability in the presence of site or communication failures and to decrease retrieval costs by local access if possible. Our system is completely decentralized and nodes can be removed/added dynamically. P2P is a trendy technology used for file sharing. File duplication and Regularity protection are the methods used in P2P for elevated system performance. File duplication methods indicate replica nodes without thinking about regularity protection which may lead to high overhead for redundant file duplications and regularity protection. Regularity protection methods update files without considering file duplication dynamism which may not give the accuracy of replica regularity. Hence there is a need to think about regularity protection while file duplication to achieve high performance and high availability. When data files are replicated at many nodes, regularity must be maintained among the nodes. In this paper we point out different duplication strategies that are applied P2P systems. This paper presents an Integrated file Duplication and regularity Protection mechanism. Integrated file Duplication and regularity Protection mechanism integrates the two techniques in a systematic and harmonized manner. The security has become one of the major issues for data communication over worldwide networks.
