We revisit the well-known group membership problem, and show how it can be considered a special case of a simpler problem, the set membership problem. In the set membership problem, processes maintain a set whose elements are drawn from an arbitrary univer ...
Group communication is the basic infrastructure for implementing fault-tolerant replicated servers. While group communication is well understood in the context of static systems (in which all processes are created at the start of the computation), current ...
This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring agreement on a primary (usually done using a membership service). Passive replicati ...
Peter Urban, Ilya Shnayderman and Andre Schiper Comparison of Failure Detectors and Group Membership: Performance Study of Two Atomic Broadcast Algorithms In Proc. of the 2003 International Conference on Dependable Systems and Networks (DSN), pages 645-654 ...
Agreement problems, such as consensus, atomic broadcast, and group membership, are central to the implementation of fault-tolerant distributed systems. Despite the diversity of algorithms that have been proposed for solving agreement problems in the past y ...
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. While many middleware archi ...
Fault tolerance can be achieved in distributed systems by replication. However, Fischer, Lynch and Paterson have proven an impossibility result about consensus in the asynchronous system model. Similar impossibility results have been established for atomic ...
The paper presents a model for end-user directed access control to services in Internet service centres that, beside the classical Internet services (e.g., e-mail), offer a multitude of new services (e.g., on-line conferencing and auctioning) over the Inte ...
This paper presents the semi-passive replication technique -- a variant of passive replication -- that can be implemented in the asynchronous system model without requiring a membership service to agree on a primary. Passive replication is a popular replic ...
Failure detection and group membership are two important components of fault-tolerant distributed systems. Understanding their role is essential when developing efficient solutions, not only in failure-free runs, but also in runs in which processes do cras ...
