Various applications and demands of network services keep emerging with the progress of Internet technologies. To serve customers well, a system, CQM (Customer QoS Management) System, is developed to manage the performance and quality of services. As new web applications continue skyrocketing, apart from knowing the quality of networks, customers would also like to master the usage of the services, the bandwidth usage of hosts, and the conversation of traffic between sites. Based on the above points, CQM uses NetFlow technique to achieve the above requirements. This article will introduce NetFlow technique and its functions and structure, and illustrate the implementation of NetFlow technique on CQM as well as the results.
