Multiplexing models are common in resource sharing communication media such as buses, crossbars and networks. While sending packets over a multiplexing node, the packet delay bound can be computed using network calculus models. The tightness of such delay bound remains an open problem. This paper studies the multiplexing models for weighted round robin scheduling with different traffic arrival curves, and analyzes per-flow packet delay bounds with different service properties. We empirically evaluate the tightness of the delay bounds. Our results show the quality of different analysis models, and how influential each parameter is to tightness.
