METHOD APPARATUS AND COMPUTER PROGRAM FOR ANALYZING PERFORMANCE OF NETWORK APPLICATION IN SOFTWARE DEFINED NETWORKING ENVIRONMENT

摘要

The present invention relates to a method, apparatus and computer program for analyzing network application program performance. A method for analyzing performance of a network application program operating in a controller of a software defined networking environment according to an exemplary embodiment of the present invention includes: identifying information of an application program, flow information, and network setting information of a network controlled by the controller The method includes the steps of receiving an input, emulating a virtual network using the network configuration information, executing a virtual network using the flow information, measuring a time for the controller to process the flow, Extracting information corresponding to the identification information of the application program from the extracted information, and analyzing the performance degradation factor of the application program using the extracted information. According to the present invention, a network manager can automatically find a core path and a hot spot while using an existing profiling method, so that performance analysis can be simplified compared to the conventional method, and time required for performance analysis can be shortened It is effective.;
