Internet cascading fault diagnosis analytic system

Abstract

The invention discloses an internet cascading fault diagnosis analytic system which is used for analyzing the system structure, robust performance and fault diagnosis of an existing internet. In accordance with matrix data of the existing internet, randomness attack and certainty attack are conducted on the internet, the successive fault propagation and robust performance are analyzed when a network is attacked, a scheme for improving the self-healing performance of the network is put forward, and the robustness of the network is improved. Fault propagation prediction is achieved on a hardware platform, probe monitoring node faults can be sent, failure nodes are positioned, the positional information of the nodes and the propagation condition of successive faults can be returned, returned signals are analyzed and processed through an ARM processor, finally, the ARM is in communication with a GSM module by sending AT instructions to a serial port, the ARM sends information to a mobile phone of an administrator through a GSM network, and thus network faults can be detected in real time and be processed in time. The internet cascading fault diagnosis analytic system has the advantages of being simple in structure, high in operability, convenient to try out, low in cost and the like.

Description

technical field [0001] The invention relates to Internet technology, in particular to an Internet cascade fault diagnosis and analysis system. Background technique [0002] The Internet is a major frontier research field of information science today, and it is also an important platform for the economic development of the information industry. Macro-topology measurement of the Internet backbone network and robust research on this basis are the cornerstones for further understanding of Internet laws, effective discovery and utilization of Internet resources, and efficient and secure development of Internet applications. In terms of network robustness research, according to people's analysis of network failures, it is found that attacks on a small number of routing nodes in the Internet will cause node overload and failure. But the failure didn't stop there, the failed node forced the rerouting of data packets in the network, which could cause the overload failure of other ro...
