Precision Enhanced Active Queue Management Algorithm BLUE+
一种精确度加强的主动队列管理算法BLUE+*

Active queue management algorithm is an important mechanism of IP congestion control. As a kind of typical active queue management algorithm, BLUE uses packet loss and link idle events to manage congestion, but its performance is still unstable.This paper improved BLUE algorithm, proposed a precision enhanced active queue management algorithm BLUE+ and applied BLUE+ to the model of DiffServ. Simulations experiments show that BLUE+ improves the precision of queue management and the performance of BLUE algorithm,supports the DiffServ effectively.
