A network troubleshooting system based on software-defined network technology and its working method

Abstract

The invention discloses a network troubleshooting system based on software-defined network technology and a working method thereof. The system mainly includes a message interceptor, a monitoring platform, an interactive client, a fault detection application and a probe generator. The interceptor intercepts the OpenFlow message of the controller, and adds actions such as mirroring to the new flow table before sending it out. The data packets matching the table items will be mirrored to the monitoring platform for processing including journey assembly, hook triggering, and data statistics storage. In the process, the user queries and interprets the processing results through the client and the fault detection application, thereby completing the network monitoring and fault analysis functions. Under the existing network and hardware conditions, the present invention provides a seamless automatic troubleshooting solution including problem abstraction, query language, monitoring platform and fault detection application components, which is suitable for data center network environment and can Covers a variety of common network faults, and also provides a well-designed API interface for easy 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
