Network fault processing method, device and system

Abstract

The invention relates to a network fault processing method, device and system. The network fault processing method is applied to trunk link fault processing of a network management system with a centralized topological structure. The network fault processing method comprises the following steps that: when a link from a management domain to a central server fails, a pre-appointed super node in the management domain informs other host machines in the management domain of sending data to the super node, wherein the super node is one of the host machines in the management domain; and the super node receives and stores the data, processes the data sent by other host machines according to a preset rule, and records processing information of the data. By utilizing the network fault processing method, device and system, faults such that a link of the network management system with the centralized topological structure is interrupted and blocked, and the server is out of work can be timely processed; a client can guarantee the effectiveness of a network management strategy under the condition that the link of the server is interrupted; and therefore, the reliability and security of a managed system and the reliability and security of a network are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network fault processing method, device and system. Background technique [0002] A P2P (Peer to Peer, peer-to-peer connection) network is also called a peer-to-peer network or a peer-to-peer network. At present, P2P network has been required by more and more users, and it is becoming more and more popular as a standard way of distributing information, because its structure makes the network rich in scalability, and it has higher efficiency and better performance. P2P networks are decentralized, self-organizing, and dynamic in the purest sense, and provide an alternative to the traditional server-client computing model. The server-client structure allows users to connect to a server, although the server is scalable, there is always a limit. The P2P network has almost unlimited expansion possibilities. According to the structural relationship, the P2P network system can be ...

Problems solved by technology

[0012] For most failures, the system can handle it by itself without affecting the system, but there are two situations that will cause the system to fail:

[0013] The first is that the central server is paralyzed

At this time, the data sent by the hosts in all management domains will not be received by the central server, the management domain of the entire system will be out of control, and the system will fail.

[0014] The second is a fault in which one or several links are interrupted

like Figure 4 and Figure 5 As shown in , the interruption of the link between the management domain and the central server will also cause the management domain to lose control, so that the clients in the management domain cannot access the central server
