Poly-Exp Bounds in Tandem Queues
Florin Ciucu, Sima Mehri
When the arrival processes are Poisson, queueing networks are well-understood in terms of the product-form structure of the number of jobs at the individual queues; much less…
On the Throughput Optimization in Large-Scale Batch-Processing Systems
Sounak Kar, Robin Rehrmann, Arpan Mukhopadhyay +5
We analyze a data-processing system with clients producing jobs which are processed in \textit{batches} by parallel servers; the system throughput critically depends on the…
Contrasting Effects of Replication in Parallel Systems: From Overload to Underload and Back
Felix Poloczek, Florin Ciucu
Task replication has recently been advocated as a practical solution to reduce latencies in parallel systems. In addition to several convincing empirical studies, some others provi…
Exact Analysis of TTL Cache Networks: The Case of Caching Policies driven by Stopping Times
Daniel S. Berger, Philipp Gland, Sahil Singla +1
TTL caching models have recently regained significant research interest, largely due to their ability to fit popular caching policies such as LRU. This paper advances the state-of-…
Towards a System Theoretic Approach to Wireless Network Capacity in Finite Time and Space
Florin Ciucu, Ramin Khalili, Yuming Jiang +2
In asymptotic regimes, both in time and space (network size), the derivation of network capacity results is grossly simplified by brushing aside queueing behavior in non-Jackson ne…
On the Catalyzing Effect of Randomness on the Per-Flow Throughput in Wireless Networks
Florin Ciucu, Jens Schmitt
This paper investigates the throughput capacity of a flow crossing a multi-hop wireless network, whose geometry is characterized by general randomness laws including Uniform, Poiss…
Sharp Bounds in Stochastic Network Calculus
Florin Ciucu, Felix Poloczek, Jens Schmitt
The practicality of the stochastic network calculus (SNC) is often questioned on grounds of potential looseness of its performance bounds. In this paper it is uncovered that for bu…
Delay Bounds for Networks with Heavy-Tailed and Self-Similar Traffic
Jorg Liebeherr, Almut Burchard, Florin Ciucu
We provide upper bounds on the end-to-end backlog and delay in a network with heavy-tailed and self-similar traffic. The analysis follows a network calculus approach where traffic…
