In Differentiated Services (DiffServ) architecture, we define the per-hop QoS as the throughput, delay, jitter, and loss rate experienced by traffic crossing a Per-Hop Behavior (PHB). In this paper, we use a statistical approach that is based on experiments on a real network testbed to characterize the per-hop QoS of a given PHB. Specifically, we employ a full factorial statistical design of experiments to study the effects of different PHB configurations and input traffic scenarios on perhop QoS. We use Analysis of Variance (ANOVA) to identify the input and PHB configuration parameters that have the most significant influence on per-hop QoS. Then, multiple regression analysis is applied to construct models for the per-hop QoS with respect to these parameters. The overall approach is shown to be effective and capable of characterizing any given PHB, within the ranges of the experiments, and for construction of functional relationships for the PHB output parameters. The approach in this paper forms a "fundamental" step towards achieving predictable end-to-end QoS when applying statistical QoS control at intermediate nodes. |
