Study of network flow timeout strategy

Firstly discussed the state-of-art of flow timeout strategies, and pointed out where they were applicable and their shortcomings. Presented a two-level self-adaptive timeout (TSAT) strategy which handles flows with different timeout strategy according to its feature. This method could improve the performances of network measurement and the efficiency of the resource usage of measurement systems. Some experiments were employed to show the rationality of TSAT strategy. Then the fitness area of strategy was anatomized as well.
