Atomic broadcast primitives are often proposed as a mechanism to allow fault-tolerant cooperation between sites in a distributed system. Unfortunately, the delay incurred before a message can be delivered makes it difficult to implement high performance, s ...
This paper addresses the problem of atomic multicasting messages in asynchronous distributed systems. Firstly, we give a characterization of the notion of ``genuine atomic multicast''. This characterization leads to a better understanding of the difference ...
Agreement problems constitute a fundamental class of problems in the context of distributed systems. All agreement problems follow a common pattern: all processes must agree on some common decision, the nature of which depends on the specific problem. This ...
Distributed systems are the basis of widespread computing facilities enabling many of our daily life activities. Telebanking, electronic commerce, online booking-reservation, and telecommunication are examples of common services that rely on distributed sy ...
The consensus problem is a fundamental paradigm for fault-tolerant distributed computing. It abstracts a family of problems known as agreement problems, e.g., atomic broadcast, atomic commitment, group membership, and leader election. Any solution to Conse ...
This paper presents the abstraction of lazy consensus and argues for its use as an effective component for building distributed agreement protocols in practical asynchronous systems where processes and links can crash and recover. Lazy consensus looks like ...
Contention-Aware Metrics for Distributed Algorithms: Comparison of Atomic Broadcast Algorithms Peter Urban, Xavier Defago and Andre Schiper Resource contention is widely recognized as having a major impact on the performance of distributed algorithms. Neve ...
This paper describes a modular approach for the construction of fault-tolerant agreement protocols. The approach is based on a generic consensus service. Fault-tolerant agreement protocols are built using a client-server interaction, where the clients are ...
Replication is a powerful technique for increasing availability of a distributed service. Algorithms for replicating distributed services do however face a dilemma: they should be (1) efficient (low latency), while (2) ensuring consistency of the replicas, ...
In network (e.g., Web) servers, it is often desirable to isolatethe performance of different classes of requests from each other. That is, one seeks to achieve that a certain minimalproportion of server resources are available for a class ofrequests, indep ...
