Optimal Decision Making in Active Queue Management
Sounak Kar, Bastian Alt, Heinz Koeppl +1
Active Queue Management (AQM) aims to prevent bufferbloat and serial drops in router and switch FIFO packet buffers that usually employ drop-tail queueing. AQM describes methods to…
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…
Collaborative Uploading in Heterogeneous Networks: Optimal and Adaptive Strategies
Wasiur R. KhudaBukhsh, Bastian Alt, Sounak Kar +2
Collaborative uploading describes a type of crowdsourcing scenario in networked environments where a device utilizes multiple paths over neighboring devices to upload content to a…
A Generalized Performance Evaluation Framework for Parallel Systems with Output Synchronization
Wasiur R. KhudaBukhsh, Sounak Kar, Amr Rizk +1
Frameworks, such as MapReduce and Hadoop are abundant nowadays. They seek to reap benefits of parallelization, albeit subject to a synchronization constraint at the output. Fork-Jo…
Optimizing Stochastic Scheduling in Fork-Join Queueing Models: Bounds and Applications
Wasiur R. KhudaBukhsh, Amr Rizk, Alexander Frömmgen +1
Fork-Join (FJ) queueing models capture the dynamics of system parallelization under synchronization constraints, for example, for applications such as MapReduce, multipath transmis…
