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 ...
A distributed algorithm comprises a collection of sequential-code entities, which are spread over different computers connected to a network. The process of designing a distributed algorithm is influenced by the assumptions we make on the computational env ...
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 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 ...
This paper extends the failures detector approach from crash-stop failures to muteness failures. Muteness failures are malicious failures in which a process stops sending algorithm messages, but might continue to send other messages, e.g. 'I-am-alive' mess ...
Distributed computing is one of the major trends in the computer industry. As systems become more distributed, they also become more complex and have to deal with new kinds of problems, such as partial crashes and link failures. To answer the growing deman ...
Consensus is one of the most fundamental problems in the context of fault-tolerant distributed computing. The problem consists, given a set P of processes having each an initial value vi, in deciding among P on a common value v. In 1985, Fischer, Lynch and ...
Due to their nature, distributed systems are vulnerable to failures of some of their parts. Conversely, distribution also provides a way to increase the fault tolerance of the overall system. However, achieving fault tolerance is not a simple problem and r ...
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 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 ...
