Caching and Neutrality
Pavlos Nikolopoulos, Muhammad Abdullah
We are used to defining network neutrality as absence of traffic differentiation, like policing or shaping. These mechanisms, however, are often not what determines end-users’ quality of experience (QoE). Most content today is accessed through edge caches, ...
ACM Association for Computing Machinery2023Localizing Traffic Differentiation
Pavlos Nikolopoulos, Muhammad Abdullah, Zeinab Shmeis
Network neutrality is important for users, content providers, policymakers, and regulators interested in understanding how network providers differentiate performance. When determining whether a network differentiates against certain traffic, it is importa ...
2023Dynamic Personalized Ranking
Personalized ranking methods are at the core of many systems that learn to produce recommendations from user feedbacks. Their primary objective is to identify relevant items from very large vocabularies and to assist users in discovering new content. These ...
EPFL2022Oracular Byzantine Reliable Broadcast
Rachid Guerraoui, Manuel José Ribeiro Vidigueira, Martina Camaioni, Matteo Monti
Byzantine Reliable Broadcast (BRB) is a fundamental distributed computing primitive, with applications ranging from notifications to asynchronous payment systems. Motivated by practical consideration, we study Client-Server Byzantine Reliable Broadcast (CS ...
Schloss Dagstuhl - Leibniz-Zentrum für Informatik2022Recommendation on Live-Streaming Platforms: Dynamic Availability and Repeat Consumption
Live-streaming platforms broadcast user-generated video in real-time. Recommendation on these platforms shares similarities with traditional settings, such as a large volume of heterogeneous content and highly skewed interaction distributions. However, sev ...
ASSOC COMPUTING MACHINERY2021The Impact of Collaborative Scheduling and Routing for Interconnected Logistics: A European Case Study
Michel Bierlaire, Shadi Sharif Azadeh, Mohammad Yousef Maknoon, Jianghang Chen
Interconnected logistics system can play an important role towards having a more sustainable green freight transport. Recently, after introducing the concept of Physical Internet (PI), researchers have started to explore the opportunities and challenges th ...
Springer, Cham2021Break-even Distance for MVDC Electricity Networks According to Power Loss Criteria
The medium voltage direct current (MVDC) technology is emerging in electricity networks includingpoint-to-point transmission, distribution networks and collection networks for renewable energysources. In this article the MVDC break-even distance (with resp ...
IEEE2021Solid State Bus Tie Switch for Shipboard Power Distribution Networks
Recent trends in shipboard power distribution network design, such as the transition from AC to DC result in new challenges on the issue of distribution network protection. Devices such as a solid state bus tie switch provide a first line of defence agains ...
2020Privacy-preserving photo sharing based on blockchain
Touradj Ebrahimi, Pablo Pfister
Sharing photos online has become an extremely popular activity, raising a wide concern on privacy issues related to the shared content. ProShare, a photo-sharing solution developed by Multimedia Signal Processing Group of EPFL addresses some of these priva ...
SPIE-INT SOC OPTICAL ENGINEERING2020Caching (Bivariate) Gaussians
Michael Christoph Gastpar, Guillaume Jean Op 't Veld
Caching is a technique that alleviates networks during peak hours by transmitting partial information before a request for any is made. In a lossy setting of Gaussian databases, we study a single-user model in which good caching strategies minimize the dat ...
