An Enhanced RED-Based Scheme for Differentiated Loss Guarantees

Abstract. Recently, researchers have explored to provide a queue management scheme with differentiated loss guarantees for the future Internet. The Bounded Random Drop (BRD), known as the best existing scheme, is one of such efforts which guarantees strong loss differentiation to the level of traffic in the different service classes. Even though BRD has several benefits such as low complexities and good functionalities, we identify that it has some shortcomings such as low throughput, long queuing delays, and selection problem of optimal values of parameters. Specifically, the shortcomings stem from calculating drop probabilities based on the arrival rate estimation and dropping incoming packets randomly with calculated drop probabilities without considering the current buffer occupancy. A multiple queue management scheme based on differential drop probability, called MQDDP, is proposed to overcome BRD's shortcomings as well as support absolute loss differentiation. This scheme ex...
