Bounding Superposed On-Off Sources -- Variability Ordering and Majorization to the Rescue
Abstract
This report considers the problem of bounding the loss rate of the aggregation of independent on-off sources in a bufferless model by the loss rate resulting from the aggregation of i.i.d. on-off sources. This is done through a unified framework based on the interplay of well-known results from the theory of variability orderings with the concept of majorization ordering. The author uses a basic comparison result to readily derive a bound of Rasmussen et al. for heterogeneous sources and an upper bound of Mao and Habibi for homogeneous sources. He also discusses a second upper bound proposed by these authors, and argues that this conjectured upper bound is too tight and should be replaced by a new and provably correct upper bound.
