Performance bounds for priority-based stochastic coflow scheduling
Olivier Brun, Balakrishna J. Prabhu
We consider the coflow scheduling problem in the non-clairvoyant setting, assuming that flow sizes are realized on-line according to given probability distributions. The goal is to…
Weighted Scheduling of Time-Sensitive Coflows
Olivier Brun, Rachid El-Azouzi, Quang-Trung Luu +3
Datacenter networks commonly facilitate the transmission of data in distributed computing frameworks through coflows, which are collections of parallel flows associated with a comm…
Markovian queues with Poisson control
R. Núñez-Queija, B. J. Prabhu, J. A. C. Resing
We investigate Markovian queues that are examined by a controller at random times determined by a Poisson process. Upon examination, the controller sets the service speed to be equ…
DCoflow: Deadline-Aware Scheduling Algorithm for Coflows in Datacenter Networks
Quang-Trung Luu, Olivier Brun, Rachid El-Azouzi +3
Datacenter networks routinely support the data transfers of distributed computing frameworks in the form of coflows, i.e., sets of concurrent flows related to a common task. The va…
Partial Server Pooling in Redundancy Systems
Akshay Mete, D. Manjunath, Jayakrishnan Nair +1
Partial sharing allows providers to possibly pool a fraction of their resources when full pooling is not beneficial to them. Recent work in systems without sharing has shown that r…
Sharing within limits: Partial resource pooling in loss systems
Anvitha Nandigam, Suraj Jog, D. Manjunath +2
Fragmentation of expensive resources, e.g., spectrum for wireless services, between providers can introduce inefficiencies in resource utilisation and worsen overall system perform…
Incentive-rewarding mechanisms to stimulate participation in heterogeneous DTNs
Rachid El-Azouzi, Ahmed El Ouadrhiri, Balakrishna Prabhu +2
Delay Tolerant Networks (DTNs) rely on the cooperation of nodes in a network to forward a message from its source to its destination. Most of previous studies on DTNs have focused…
Asymptotics of Insensitive Load Balancing and Blocking Phases
Matthieu Jonckheere, Balakrishna Prabhu
We address the problem of giving robust performance bounds based on the study of the asymptotic behavior of the insensitive load balancing schemes when the number of servers and th…
Information dissemination processes in directed social networks
Konstantin Avrachenkov, Koen De Turck, Dieter Fiems +1
Social networks can have asymmetric relationships. In the online social network Twitter, a follower receives tweets from a followed person but the followed person is not obliged to…
Bandwidth sharing networks with priority scaling
Mathieu Feuillet, Matthieu Jonckheere, Balakrishna J. Prabhu
In multi-class communication networks, traffic surges due to one class of users can significantly degrade the performance for other classes. During these transient periods, it is t…
