XTC: AN ACTIVE VIRTUAL QUEUE (AVQ) ALGORITHM FOR ACTIVE QUEUE MANAGEMENT

ABSTRACT
Virtual Queue-based marking schemes have been recently proposed for AQM (Active Queue Management) in Internet routers. We consider a particular scheme, which we call the Adaptive Virtual Queue (AVQ), and study its following properties: stability in the presence of feedback delays, its ability to maintain small queue lengths and its robustness in the presence of extremely short flows (the so-called web mice). Using a linearized model of the system dynamics, we present a simple rule to design the parameters of the AVQ algorithm. We then compare its performance through simulation with several well-known AQM schemes such as RED, REM, PI controller and a non-adaptive virtual queue algorithm. With a view towards implementation, we show that AVQ can be implemented as a simple token bucket using only a few lines of code. The work presents a design of an AVQ Algorithm for AQM for online payment of school fee. Online is direct communication between a user and a computer which allows the request to be processed and the result displayed immediately on the terminal screen. An AVQ algorithm for AQM for online payment of school fee are used for processing of student various fees like accommodation fee and school fee etc.
