SDN (Software Defined Network) network fault analyzing method and device

Abstract

The invention provides a SDN (Software Defined Network) network fault analyzing method and a device. a detection message is built according to a SDN controller, and a detector is generated on an embodiment built on each SDN switch in a service flow path. The well-built detection message is transmitted to a service flow test ending point according to the service flow path to execute fault detection on the service flow path starting from a test starting point. The SDN controller further receives detection results reported by the detectors and a service flow path fault analyzing network topology and / or a result list is generated according to the detection results. Thus, fault analysis of the service flow path in the SDN network environment can be well realized.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for fault analysis of a service flow path in an SDN (Software Defined Network, software-defined network) network and a corresponding device. Background technique [0002] With the continuous development of Internet services, the time required for Internet services to be deployed on the Internet is getting shorter and shorter. For example, a few years ago, a service deployment often took several months and required a lot of manpower. Now an Internet business may require deployment within a few days with a small amount of manpower. How to quickly deploy an Internet service involves some new technologies, such as SDN technology. Under the model defined by SDN, service deployment can be realized through software, thereby reducing manpower input and shortening the construction period. [0003] A typical SDN network such as figure 1 As shown, in addition t...
