Abstract: Network traffic monitoring and analysis are useful and crucial because they allow networks to be better understood, more efficiently used, and more accurately evaluated. Heterogeneous networks are widely used because they enable public networks with improved coverage, capacity, and communication. This paper proposes a system design using both sFlow and NetStream technologies for traffic performance analysis in heterogeneous networks. This sFlow+NetStream design should enable the system to obtain network traffic data more comprehensively and accurately (compared with a system that uses only one of the two technologies) and to largely reduce the pressure on the monitoring and analysis system (compared with a system that uses traditional port mirroring technology). To verify the design objects, we built a test environment with an H3C router and an eNSP simulator and conducted experimental tests in it. The test results proved the aforementioned system design to be valid and feasible.
