Abstract

Flash crowds often make users suffer from long startup delays, high reject rate and bad service. A novel user access control algorithm based on capacity-aware is proposed to tackle the problems flash crowds bring. The algorithm controls users to enter at a proper rate to prevent the high user arrival rate to slow down the increase of system scale. Also, it gives high-bandwidth users the priority to enter the system to increase the system service capacity as quickly as possible. Moreover, it considers the waiting time of the low-bandwidth users and prevent these users from leaving the system for waiting too long. A model for evaluation of the new user access control algorithm is also given. The model analysis and related experiments reveal that the new algorithm can effectively deal with the flash crowd problems and improve the quality of service for users by reducing the startup delay and service reject rate.
