Abstract

Abstract: This paper presents the Decoupled Class Based Scheduling, a CBQ-derived scheduling algorithm. Main advantages of D-CBQ are a new set of rules for distributing excess bandwidth and the ability to guarantee bandwidth and delay in a separate way, whence the name "decoupled"; moreover D-CBQ guarantees better delay bounds and more precise bandwidth assignment. This paper presents D-CBQ main points and discusses the choices for the implementation of the algorithm.
