Method, apparatus and system for diagnosing whether the node is abnormal in peer-to-peer network

Abstract

The embodiment of the invention provides a method, a device and a system for diagnosing whether nodes are normal or abnormal, and belongs to the communication field. The method comprises the following steps of: sending a diagnosis message with a message identifier to be detected; judging whether a confirmation message which corresponds to the diagnosis message and is sent by the nodes is received; and judging out the nodes are normal nodes in the condition that the conformation message is received; otherwise, judging out the nodes are abnormal nodes. The embodiment of the invention also provides a device for diagnosing whether nodes are normal or abnormal, an intermediate node device and a system for diagnosing whether nodes are normal or abnormal. The method, the device and the system have the advantages of diagnosing the nodes to be normal or abnormal nodes.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method, device and system for diagnosing whether a node is abnormal in a peer-to-peer network. Background technique [0002] Peer-to-peer network P2P (peer-to-peer) is a distributed, network participants share part of their hardware resources, such as processing power, storage capacity, network connection capabilities, printers, etc., these shared resources need to be distributed by the network Provide services and content, which can be directly accessed by other peer nodes Peer without going through an intermediate entity. Peer is both a resource provider and a resource acquirer in P2P. P2P breaks the traditional client / server C / S (Client / Server) model, each node in the network has the same status, each node acts as a server, and also provides services for other nodes, while enjoying Services provided by other nodes. P2P systems include structured P2P systems, unstructur...

AI Technical Summary

Problems solved by technology

[0006] Due to the existence of abnormal nodes in the prior art, messages or requests passing through the abnormal node are lost, which in turn affects the success rate of message or request forwarding in the P2P system. Knowing that the node is an abnormal node can limit the number of messages or requests passing through the abnormal node. number, and there is no method for diagnosing whether a node is abnormal in the prior art, so it is impossible to know whether the node is an abnormal node
