Method for controlling node to join peer-to-peer network and device thereof

Abstract

The invention discloses a method for controlling a node to join a peer-to-peer network and a device thereof, and belongs to the technical field of peer-to-peer networks. The method comprises the following steps: receiving a request message of joining the peer-to-peer network from the node; and determining to refuse the node to join the peer-to-peer network when the node is not permitted to join the peer-to-peer network according to at least one of historical information of the node joining the peer-to-peer network and historical information of the received request message of joining the peer-to-peer network. The device comprises a receiving module and a processing module. The method and the device help realize control of the node in joining the peer-to-peer network, and inhibit the node tofrequently join the peer-to-peer network, thus solving the problems of peer-to-peer network route flapping, unavailable resources and even node loss, node denial of service and the like caused by frequent joining of malicious nodes to a certain extent. Compared with the existing Puzzle mechanism, the method and the device do not need to store a great amount of problems, help greatly lower expenditure and have better control effect.

Description

technical field [0001] The invention relates to the technical field of peer-to-peer networks, in particular to a method and device for controlling nodes to join the peer-to-peer network. Background technique [0002] P2P (Peer to Peer, peer-to-peer network) is formed by connecting multiple independent nodes, and these nodes are called peer-to-peer nodes. Each peer node contributes its own capabilities and cooperates with each other to provide peer-to-peer network services. The current peer-to-peer network services mainly include distributed storage services and distributed transmission services. A peer-to-peer network is not an actual physical network but a logical network, which is carried on other networks such as the Internet. Usually, a peer-to-peer network is formed by peer nodes through transport layer connections such as TCP connections to form a topology. These transport layer connections act as A logical link for a peer-to-peer network. Peer-to-peer network is ess...

Problems solved by technology

[0010] The effect of the first method depends heavily on the specific Puzzle mechanism used. It needs to store a large number of puzzles, and the implementation cost is relatively high. When the malicious node can give the answer, it still cannot prevent the malicious node from frequently joining and exiting the peer-to-peer network.

For example, if the problem is to provide the number represented by the picture, the method will fail because the malicious node adopts the corresponding picture recognition technology

The second method cannot solve the routing jitter, signaling overhead, and possible denial of service caused by malicious nodes frequently joining the peer-to-peer network, and if the malicious node joins the peer-to-peer network multiple times, it will take away the published resources and its backup, these resources are still unavailable or even lost
