Enabling ICN in IP networks via DNS Extensions: A Measurement Study
- Hilt V.
- Satzke K.
ICN promises benefits to users and service providers along several dimensions, including lower response time, nearest-replica routing, intrinsic content integrity without external network-level indicators, location-independent naming and improved support for mobility. However, these benefits come at non-trivial cost as many ICN proposals call for adding significant complexity to the network. ...

Future Cognitive Mobile Networks : Connecting Management and Orchestration
- Gruber M.
The goals when running a mobile network have remained the same over the years, namely reducing CAPEX/OPEX by decreasing the necessary level of manual intervention and increasing the network performance. However, the complexity has dramatically increased: 5G networks will have to be able to deal with dynamic slice management and ...

Go-Index: Applying supply networks principles as Internet robustness metrics
- Bachmann I.
- Bustos-Jimenez J.
- Morales F.
- Silva A.
Whether as telecommunications or power systems, networks are very important in everyday life. Maintaining these networks properly functional and connected, even under attacks or failures, is of special concern. This topic has been previously studied with a whole network robustness perspective. With this perspective, whenever a node is removed the ...
Opinion Manipulation in Social Networks
- Silva A.
In this work, we are interested in finding the most efficient use of a budget to promote an opinion by paying agents within a group to supplant their true opinions. We model opinions as continuous scalars ranging from 0 to 1 with 1 representing extremely positive opinion. We focus on ...
MIMO Equalization for Multi-Gbit/s Communication Under Channel Variability
- D. Vande Ginste
- Guenach M.
- Jacobs L.
- Jelle Bailleul
- Marc Moeneclae
- P. Manfredi
Multiple-input multiple-output (MIMO) equalization at the transmitter and/or receiver has been shown to enable multi-Gbit/s communication over lowcost electrical interconnects. Because of the high operating frequencies, however, the interconnects become susceptible to manufacturing tolerances and the equalization filters must be adjusted to the specific channel realization to achieve optimal performance. ...
On the Fundamental Characteristics of Ultra-Dense Small Cell Net
- Claussen H.
- Lopez-Perez D.
- Ming Ding
- Mohamed Ali Kaafarx
In order to cope with the forecasted 1000x increase in wireless capacity demands by 2030, network operators tend to aggressively densify the network infrastructure, so as to reuse the spectrum as much as possible. However, it is important to realise that these new ultra-dense small cell networks are fundamentally different ...
A Theory of Nonlinear Signal-Noise Interactions in Wavelength Division Multiplexed Coherent Systems
- Ghazisaeidi A.
a general theory of nonlinear signal-noise interactions for wavelength division multiplexed fiber-optic coherent transmission systems is presented. This theory is based on the regular perturbation treatment of the nonlinear Schrodinger equation, which governs the wave propagation in the optical fiber, and is exact up to the first order in the ...

With the explosion of the number and variety of connected objects, it is necessary to define a system of recommendation of IoT services to the users so that they better use the connected objects that are at their disposal. The purpose of this recommendation system is to provide the user ...
Non-Intrusive and Efficient Detection of Latent Reliability Bottlenecks within Cloud Storage Services
- Chen R.
- Zhai E.
Large-scale storage systems, common in cloud computing, employ replication techniques to ensure reliability. Along with the increasing scale of modern cloud platforms, however, replica servers may inadvertently depend on deep, common infrastructure components, e.g., switches and DNS servers. Such unexpected common dependencies are defined as Latent Reliability Bottlenecks (or LRBs), ...
Optimal Channel Allocation with Scalable TTI for Heterogeneous Services
- Fountoulakis E.
- Liao Q.
- Pappas N.
- Suryaprakash V.
- Yuan D.
The rapid growth in the number of varieties of connected devices requires 5G wireless systems to cope with a very heterogeneous traffic mix. As a consequence, the use of a fixed Transmission Time Interval (TTI) during transmission is not necessarily the most efficacious method for the simultaneous service of such ...

Repeated CTD -- Unleashing the Potential in Multiple Testing Iterations
- Segall I.
Test design is the process of planning and designing the tests to be performed on a software system. The time scale at which organizations perform and modify their test design is typically orders of magnitude larger than that of development, especially in modern agile development processes.

Multi-Objective Data Placement for Multi-Cloud Socially Aware Services
- Du W.
- Fu X.
- Jiao L.
- Li J.
Socially aware services are services where users form social relationships and interact with one another, which often have a large user base and every user's data have to be partitioned and replicated over multiple geographically distributed clouds. Choosing which cloud to place data, however, is difficult. Effective data placements entail ...
DualQ Coupled AQM for Low Latency, Low Loss and Scalable Throughput
- De Schepper K.

Data Centre TCP (DCTCP) was designed to provide predictably low queuing latency, near-zero loss, and throughput scalability using explicit congestion notification (ECN) and an extremely simple marking behaviour on switches. However, DCTCP does not co-exist with existing TCP traffic---throughput starves. So, until now, DCTCP could only be deployed where a ...
