Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] see figure 1 , Figure 4 , the system includes an SDN controller and a plurality of SDN switches, wherein the multiple SDN switches are connected to each other, and the SDN controller and the SDN switches interact through the added expansion interface; the SDN controller realizes the network topology Real-time detection and periodic detection of each link, and real-time monitoring of the status of SDN switches to maintain the overall network topology, so as to monitor the entire network and realize network fault analysis;

[0038] The SDN controller includes: an OpenFlow module, an OpenFlow extension module, an event module, a topology module, and a detection module; the detection module further includes a real-time detection module and a periodic detection module;

[0039] The SDN controller and the SDN switch mainly interact through the added expansi...

Abstract

The invention relates to a system and a method for realizing automatic network failure analysis based on SDN technology. The system comprises one SDN controller and multiple SDN switches. The SDN controller realizes real-time detection and cycle detection of each link in network topology, and monitors states of the SDN switches in real time and maintains the global network topology. The SDN controller comprises an OpenFlow module, an OpenFlow extension module, an event module, a topology module and a detection module. The detection module comprises a real-time detection module and a cycle detection module. With the system and the method, the whole network can be monitored, and network failure analysis is realized.

Description

technical field [0001] The invention specifically relates to a system and method for automatic network fault analysis, belonging to the field of network fault analysis. Background technique [0002] With the rapid development of business fields such as social networks, mobile Internet, and the Internet of Things, Big Data is increasingly becoming the current focus, and its massive data processing also puts forward higher requirements for the network. Big data applications rely on a pre-defined computing model, run under a centralized management structure, and there are a large number of batch data transfers and related aggregation / division operations. Aggregation and division of data usually occurs between a server and a server group with many servers, which is also the most typical network traffic pattern in big data applications. Every aggregation in the process of big data processing will lead to massive data exchange between a large number of servers, which requires ext...
