A Palm Calculus Approach to the Distribution of the Age of Information
Amr Rizk, Jean-Yves Le Boudec
A key metric to express the timeliness of status updates in latency-sensitive networked systems is the age of information (AoI), i.e., the time elapsed since the generation of the…
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…
