A simulation study of a new rate-and-queue-based active queue management algorithm

Nowadays, e-queues are built up everywhere where customer online service is necessary such as in banks’ e-service, enterprises’ e-business, etc. In order to enhance quality of service (QoS), active queue management (AQM) algorithms are frequently employed due to their efficiency in congestion avoida...
