TLDR
The study indicates that, by selective packet discarding, one can properly change the distribution of the overall loss rate spectrum among the multiplexed traffic streams, which can significantly improve the transmission quality of individual services.Abstract:
Uses the well known technique of power spectral representation to characterize the second order statistics of packet loss during congestion at a statistical multiplexer. Unlike the steady state statistics, the second order statistics measures the time correlation behavior of loss. Typically, the low frequency loss power is associated with long periods of highly consecutive loss. The effect of the loss rate power spectrum on transmission qualities is service dependent. The study indicates that, by selective packet discarding, one can properly change the distribution of the overall loss rate spectrum among the multiplexed traffic streams, which can significantly improve the transmission quality of individual services. Moreover, with the design of multi-level buffer overload control, one can tune the loss rate steady state distribution of different priority streams to a piece-wise step function, which minimizes the packet loss impact on service qualities. >read more

Stochastic theory of a data-handling system with multiple sources
TL;DR: In this article, the authors considered a physical model in which a buffer receives messages from a finite number of statistically independent and identical information sources that asynchronously alternate between exponentially distributed periods in the ‘on’ and ‘off' states.

TL;DR: This demonstrates that statistical or asynchronous time-division multiplexing (TDM) can efficiently absorb temporal variations of the bit rate of individual sources without the significant variations in reception quality exhibited by multimode videocoders for synchronous TDM or circuit-switched transmission.

N. Yin,San-Qi Li,T.E. Stern +2 more
TL;DR: In order to reduce the time delays as well as multiplexer memory requirements in packet voice systems, a family of congestion control schemes is proposed based on the selective discarding of packets whose loss will produce the least degradation in quality of the reconstructed voice signal.
