Multiplexing gains in bit stream multiplexors

Temporal Multiplexing Gains

Effective Bandwidth is a powerful tool in modeling bandwidth and buffer requirements for multiplexed data sources. It is often approximated that an additional service capacity equal to the effective bandwidth of the source is required for every additional data source added to the multiplexed stream given a fixed buffer size and maximum blocking probability. This implies that a multiplexing gain...

Distributed spatial multiplexing with 1-bit feedback

We analyze the feasibility of distributed spatial multiplexing with limited feedback in a slow-fading interference network with MN non-cooperating single-antenna sources and M non-cooperating single-antenna destinations. In particular, we assume that the sources are divided into M mutually exclusive groups of N sources each, every group is dedicated to transmit a common message to a unique dest...

Statistical Multiplexing of Homogeneous Streams Results in Linear Bandwidth Gains

Statistical multiplexing of traffic streams results in reduced network bandwidth requirement. The resulting gain increases with the increase in the number of streams being multiplexed together. However, the exact shape of the gain curve, as more and more streams are multiplexed together, is not known. In this paper, we first present the generalized result that the statistical gain of combining ...

Optimal Video Stream Multiplexing through Linear Programming

This paper presents a new optimal multiplexing scheme for compressed video streams based on their individual ePCRTT transmission schedules. A linear programming algorithm is proffered, which takes into account the different constraints of each client. The algorithm simultaneously finds the optimum total multiplexed and individual stream schedules that minimize the peak transmission rate. Since ...
