Abstract

To analyze scheduling algorithms in computer networks, two models have been proposed and widely used in the literature, namely the Guaranteed Rate (GR) server model and the Latency Rate (LR) server model. While a lot scheduling algorithms have been proved to belong to GR or LR or both, it is not clear what is the relationship between them. The purpose of this paper is to investigate this relationship. We prove that if a scheduling algorithm belongs to GR, it also belongs to LR and vice versa. In addition, we review several other models that are also used for analysis of scheduling algorithms and discuss their relationship with LR model and GR model.
