The scale of data in correlative applications system is greatly improved along with the business volume extended in the distribution network each year. Since the lack of supervision and inspection method

it's difficult to get the information from the system which has already been in operation. In that case

it also cannot analyze the information security for business. Message flow supervision and conformance testing based on IEC 61968 series standard are studied through the bypass monitoring technology. The online conformance testing method of information interaction for distributed system is proposed to support the collection

integration and analysis of the business data for the large area of production control and information management. The use of switch port mirroring bypass and IEC 61968 message comparison technologies can realize the collection of sample data and the correctness judgment of test result

covering the standard interface test

interactive scene test and performance test. The overall plan aims to satisfy distribution network's basic requirements of the information interaction consistency test. Integrating with the detection module of project development

the consistence of the test sample data with IEC 61968 series standard is verified. Finally

the test result is given.
