A Simpler and Faster NIC Driver Model for Network Functions

George Candea, Solal Vincenzo Pirelli

The advent of software network functions calls for stronger correctness guarantees and higher performance at every level of the stack. Current network stacks trade simplicity for performance and flexibility, especially in their driver model. We show that p ...

Prediction of the Inter-Node Communication Costs of a New Gyrokinetic Code with Toroidal Domain

Laurent Villard, Stephan Brunner, Emmanuel Lanti, Noé Thomas Elie Ohana, Claudio Gheller, Aaron Lewis Scheinberg

We consider the communication costs of gyrokinetic plasma physics simulations running at large scale. For this we apply virtual decompositions of the toroidal domain in three dimensions and additional domain cloning to existing simulations done with the OR ...

Automated Synthesis of Adversarial Workloads for Network Functions

Aikaterini Argyraki, Luis David Figueiredo Mascarenhas Moreira Pedrosa, Arseniy Zaostrovnykh, Rishabh Ramesh Iyer, Jonas Fietz

Software network functions promise to simplify the deployment of network services and reduce network operation cost. However, they face the challenge of unpredictable performance. Given this performance variability, it is imperative that during deployment, ...

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

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

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 ...

Game Theory Meets Network Security and Privacy

Jean-Pierre Hubaux

This survey provides a structured and comprehensive overview of research on security and privacy in computer and communication networks that use game-theoretic approaches. We present a selected set of works to highlight the application of game theory in ad ...

Energy-Proportional and Scalable Networks

Nedeljko Vasic

The power consumption of the Internet and datacenter networks is already significant due to a large degree of redundancy and high idle power consumption of the network elements. Therefore, dynamically matching network resources to the actual load is highly ...

OREN: Optimal Revocations in Ephemeral Networks

Jean-Pierre Hubaux, Igor Bilogrevic

Public-key certificates allow a multitude of entities to securely exchange and verify the authenticity of data. However, the ability to effectively revoke compromised or untrustworthy certificates is of great importance when coping with misbehavior. In thi ...

Optimal Revocations in Ephemeral Networks: A Game-Theoretic Framework

Jean-Pierre Hubaux, Igor Bilogrevic

Revocation of public-key certificates is an important security primitive. In this paper, we design a fully distributed local certificate revocation scheme for ephemeral networks - a class of extremely volatile wireless networks with short-duration and shor ...

Data-centric trust in ephemeral networks

New network types require new security concepts. Surprisingly, trust – the ultimate goal of security – has not evolved as much as other concepts. In particular, the traditional notion of building trust in entities seems inadequate in an ephemeral environme ...

Revocation Games in Ephemeral Networks

Jean-Pierre Hubaux, Mark Felegyhazi

A frequently proposed solution to node misbehavior in mobile ad hoc networks is to use reputation systems. But in ephemeral networks - a new breed of mobile networks where contact times between nodes are short and neighbors change frequently - reputations ...

ProtoPeer: from Simulation to Live Deployment in One Step

Karl Aberer, Zoran Despotovic, Wojciech Galuba

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 ...
