We study the problem of statistical multiplexing of cell streams which have correlations at multiple time-scales. Each stream is modeled by a singularly perturbed Markovmodulated process with some state transitions occurring much more infrequently than others. We develop a set of large deviations results to estimate the buffer overflow probabilities in various asymptotic regimes in the buffer s...

Greetings! As we enter the second quarter of year, are thrilled to present issue Policy Studies Journal (PSJ). This features 10 top-notch research articles that cover various topics related policy theory and substantive domains. Before diving into details articles, would like share some exciting news PSJ operations. First, in February, established a strategic partnership with Seoul National Uni...

In a heterogeneous network, layered multicast is useful which enables receivers to determine the rate of a stream adaptively to their various capacities. Previous rate control schemes for layered multicast, however, treat each stream independently and cannot allocate the requested bandwidth to each stream when receivers subscribe to multiple streams. In this paper, we propose an inter-stream ra...
