Quality of Service Oriented Power Communication Network Test Mechanism

SDN technology realizes the separation of network control and data forwarding, and improves the efficiency and resource utilization of network communication. However, the current research lacks the research on network testing mechanism in SDN environment from the perspective of service quality, resulting in higher probability of network service problems and longer service repair time. In order to solve this problem, this paper first designs a network test architecture oriented to service quality under SDN environment. Secondly, the power communication network test mechanism oriented to service quality under SDN environment is designed. This mechanism includes six steps: the business management system discovers business exceptions, the test management global center triggers the test, the test management global center sends the test task to the test domain management center, the test domain management center sends the test request to the SDN domain controller, the SDN domain controller sends the flow table and feeds back the results to the test domain management center, and the test management global center collects the test domain management center results and analyzes them. Finally, the test mechanism proposed in this paper is analyzed from the two dimensions of usability and enforceability, which verifies that this mechanism has good performance.
