Network troubleshooting system based on software defined network technology and working method thereof

Abstract

The invention discloses a network troubleshooting system based on a software defined network technology and a working method thereof. The system mainly comprises a message interceptor, a monitoring platform, an interactive client, a fault detection application and a probe generator. The interceptor intercepts an OpenFlow message of the controller; and after mirror image and other actions are addedto the new flow table, the data packet matched with the table item is mirrored to a monitoring platform to carry out processing processes including journey assembly, hook triggering, data statisticalstorage and the like, and a user inquires and interprets a processing result through a client and a fault detection application, so that the network monitoring and fault analysis functions are completed. According to the invention, under the existing network and hardware conditions; a solution for seamless automatic troubleshooting including a problem abstraction component, a query language component, a monitoring platform component, a fault detection application component and the like is provided, the method is suitable for a data center network environment, various common network faults canbe covered, and an API interface with good design is further provided to facilitate function expansion.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a network troubleshooting system based on software-defined network technology and a working method thereof. Background technique [0002] With the continuous expansion of the scale of the data center network, the structure and function are becoming more and more complex, and the traffic is increasing rapidly. New network applications such as cloud computing, cloud storage and streaming media services are emerging in an endless stream, which undoubtedly poses more severe challenges to the configuration, operation and management of the current network. challenge. In this context, a new type of network architecture called Software Defined Networking (SDN) emerged as the times require, and through its core ideas of numerical control separation, software-based and centralized control, it fully meets the needs of centralized management and control of data center servers , which incre...

AI Technical Summary

Problems solved by technology

[0005] The current data center network troubleshooting system often decouples the flow collection and fault analysis process. It often uses different tools and systems to complete their respective functions, and then manually intervenes to achieve series connection, which cannot achieve seamless automatic troubleshooting. This also means longer fault duration, higher operation and maintenance costs, and a slowdown in the deployment of new network applications
