Method, system and device for controlling resource release in P2P

Abstract

The embodiment of the invention discloses a method for controlling resource release in a P2P network. The P2P network is formed by believable nodes. The method is that the authority information and / or reputation information of a client are obtained from the P2P network; and the behavior of the client releasing resources is controlled according to the authority information and / or reputation information. In the embodiment of the invention, since the resources released by the client are inspected at an accessed Peer node, the malicious behaviors of the client are prevented. Moreover, the Peer releases the relevant client information on an Overlay. When a client node is shifted to the Peer, a newly accessed Peer node obtains the authority information of the client from the Overlay and inspects and controls the accessed client releasing and obtaining resources.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, system and equipment for controlling resource release in P2P. Background technique [0002] P2P (Peer-to-Peer, peer-to-peer network) is composed of multiple nodes joining the network, also called P2P overlay network. In a peer-to-peer network, two or more PCs or other devices directly communicate or collaborate on the network, sharing common resources including processing power (CPU), programs, and data with each other. There is no central node or central server in the P2P network, and each node simultaneously assumes the triple responsibilities of information consumers, information providers and information intermediaries. Each node in the P2P network has exactly the same status, and the rights and obligations are equal. [0003] Such as figure 1 As shown, it is a P2P Overlay (overlay network) with a Peer-Client structure in the prior art. P2P Overlay add...

Problems solved by technology

Malicious clients can publish the address of the attack target as a Value and a Key corresponding to a popular content to the P2P Overlay. In this way, a large number of nodes that want to obtain this popular content will establish connections with the attack target from different places , causing the network resources of the attack object to be greatly occupied, or even paralyzed, forming a DDOS (distributed denial of service, distributed denial of service attack) on the attack object
