The impossibility of boosting distributed service resilience

Rachid Guerraoui

We study f -resilient services, which are guaranteed to operate as long as no more than f of the associated processes fail. We prove three theorems asserting the impossibility of boosting the resilience of such services. Our ﬁrst theorem allows any connect ...

Quantitative Analysis of Consensus Algorithms

André Schiper, Martin Hutle, Fatemeh Borran, Nuno Filipe de Sousa Santos

Consensus is one of the key problems in fault-tolerant distributed computing. Although the solvability of consensus is now a well-understood problem, comparing different algorithms in terms of efficiency is still an open problem. In this paper, we address ...

Detection and Recovery From Pollution Attacks in Coding Based Distributed Storage Schemes

László Czap, Levente Buttyan

We address the problem of pollution attacks in coding based distributed storage systems. In a pollution attack, the adversary maliciously alters some of the stored encoded packets, which results in the incorrect decoding of a large part of the original dat ...

How Efficient Can Gossip Be? (On the Cost of Resilient Information Exchange)

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Morteza Zadimoghaddam

Gossip, also known as epidemic dissemination, is becoming an in- creasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural ex- tension of the random phone-call ...

PaxosInside

Rachid Guerraoui, Maysam Yabandeh

Amodernmanycore architecture can be viewed as a distributed system with explicit message passing to communicate between cores. Ensuring the consistency of shared state replicated over several cores is the key to the well functioning of such a system. Yet, ...

How Efficient Can Gossip Be? (On the Cost of Resilient Information Exchange)

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Morteza Zadimoghaddam

Gossip, also known as epidemic dissemination, is becoming an increasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural extension of the random phone-call mode ...

In search of lost time

Martin Hutle

Dwork, Lynch, and Stockmeyer [3] and Lamport [4] showed that, in order to solve Consensus in a distributed system, it is sufficient that the system behaves well during a finite period of time. In sharp contrast, Chandra. Hadzilacos, and Toueg [6] proved th ...

Routing Attacks as a Viable Threat: Can Software Systems Protect Themselves?

Dan Alistarh

In this paper, we show that distributed systems are vul- nerable to routing attacks and propose an architecture to obviate this vulnerability. A somewhat surprising finding is that even a small-scale routing attack can completely dis- rupt the operation of ...

A Leader-Free Byzantine Consensus Algorithm

André Schiper, Fatemeh Borran

The paper considers the consensus problem in a partially synchronous system with Byzantine faults. It turns out that, in the partially synchronous system, all deterministic algorithms that solve consensus with Byzantine faults are leader-based. This is not ...
