Abstract:

An improved adaptive sampling algorithms to improve the efficiency and flexibility of network load measurement is proposed after the detailed research on the theory of adaptive control and traffic characteristics. Performance comparison ,shows that there is improvement by 40% on the measurement precision. It can also provide several visual outputs with different granularity to support the measurement efficiency and flexibility. So the improved algorithm suits for the environments of measuring highspeed network load with high burst arrival rate.

Key words: packet sampling, link load measurement, adaptive control
