Influence of online games traffic multiplexing and router buffer on subjective quality

This work presents a simulation study of the influence of a multiplexing method on the parameters that define the subjective quality for online games, mainly delay, jitter and packet loss. The results for an available subjective quality estimator from the literature are also shown. Two buffer implementations, each one with two buffer sizes, are tested in order to study the mutual influences of the router buffer and multiplexing on subjective quality. The results show that small buffers are more adequate to maintain delay and jitter in acceptable levels, but they increase packet loss. Multiplexing shows a clear advantage when using a buffer which size is measured in packets. A buffer with a limit in packets per second is also tested.
