Localizing Traffic Differentiation

Pavlos Nikolopoulos, Muhammad Abdullah, Aikaterini Argyraki, 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 ...

Scalable and Privacy-Preserving Federated Principal Component Analysis

Jean-Pierre Hubaux, Juan Ramón Troncoso-Pastoriza, Apostolos Pyrgelis, David Jules Froelicher, Joao André Gomes de Sá e Sousa, Jean-Philippe Léonard Bossuat

Principal component analysis (PCA) is an essential algorithm for dimensionality reduction in many data science domains. We address the problem of performing a federated PCA on private data distributed among multiple data providers while ensuring data confi ...

QUIC: Opportunities and threats in SATCOM

Ludovic Bernard Gérard Thomas, Emmanuel Qays Dubois

This article proposes a discussion on the strengths, weaknesses, opportunities and threats related to the deployment of QUIC end-to-end from a satellite-operator point-of-view. The deployment of QUIC is an opportunity for improving the quality of experienc ...

Operating System and Network Co-Design for Latency-Critical Datacenter Applications

Evangelos Marios Kogias

Datacenters are the heart of our digital lives. Online applications, such as social-networking and e-commerce, run inside datacenters under strict Service Level Objectives for their tail latency. Tight latency SLOs are necessary for such services to remain ...

R2P2: Making RPCs first-class datacenter citizens

Edouard Bugnion, Evangelos Marios Kogias, Adrien Ghosn, Georgios Prekas, Jonas Fietz

Remote Procedure Calls are widely used to connect datacenter applications with strict tail-latency service level objectives in the scale of µs. Existing solutions utilize streaming or datagram-based transport protocols for RPCs that impose overheads and li ...

Bridging the gap between dataplanes and commodity operating systems

Georgios Prekas

The conventional wisdom is that aggressive networking requirements, such as high packet rates for small messages and microsecond-scale tail latency, are best addressed outside the kernel, in a user-level networking stack. In particular, dataplanes borrow d ...

Metadata Protection Considerations for TLS Present and Future

Bryan Alexander Ford

TLS 1.3 takes important steps to improve both performance and security, so far offers little protection against traffic analysis or fingerprinting using unencrypted metadata or other side-channels such as transmission lengths and timings. This paper explor ...

MPTCP Is Not Pareto-Optimal: Performance Issues and a Possible Solution

Jean-Yves Le Boudec, Ramin Khalili, Nicolas Gabriel Gast, Miroslav Popovic

Multipath TCP (MPTCP) has been proposed recently as a mechanism for transparently supporting multiple connections to the application layer. It is under discussion at the IETF. We nevertheless demonstrate that the current MPTCP suffers from two problems: P1 ...

Low cost security for sensor networks

Christina Fragouli, Lorenzo Keller, Iris Safaka, Emre Atsan

We design and evaluate a lightweight encryption protocol suitable for sensor networks, that enables weak security in the presence of passive eavesdroppers. At every communication round, our protocol creates a key between each sensor node and the sink, by a ...

Adaptive Multiview Video Streaming: Challenges and Opportunities

Delivering multiview video content over present packet networks poses multiple challenges. First, the best effort nature of the Internet exposes media packets to variable bandwidth, loss, and delay as they traverse the network. Second, the prediction depen ...

Empirical Performance Evaluation of Data Dissemination Mechanisms for Spot Applications

Jean-Yves Le Boudec, Alaeddine El Fawal, Adel Aziz

We evaluate, by measurements on a real testbed, the performance of networking services required for spot applications. We call a “spot application” an application for smartphones (such as “Ad-hoc Flash Sales”) that disseminates information in a local neigh ...

Relational network-service clustering analysis with set evidences

Boi Faltings, Li Pu

Network administrators are faced with a large amount of network data that they need to sift through to analyze user behaviors and detect anomalies. Through a network monitoring tool, we obtained TCP and UDP connection records together with additional infor ...

One Bit Is Enough: a Framework for Deploying Explicit Feedback Congestion Control Protocols

Dejan Kostic, Nedeljko Vasic

Since the bandwidth-delay products of Internet links keep increasing, issues with TCP's convergence time, throughput, and amount of queuing in these environments are becoming more pressing. As we move toward the next-generation Internet, it is important to ...

ProtoPeer: from Simulation to Live Deployment in One Step

Karl Aberer, Wojciech Galuba, Zoran Despotovic

We present ProtoPeer, a peer-to-peer systems prototyping toolkit that allows for switching between the event driven simulation and live network deployment without changing any of the application code. ProtoPeer exports a set of APIs for message passing, me ...

Optimizing TCP Receive Performance

Willy Zwaenepoel, Aravind Menon

The performance of the networking stack in an operating system depends on the overhead incurred by two of its components: the per-byte overhead incurred in data-touching operations, and the per-packet overhead of protocol processing and other operating sys ...
