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 ...
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 ...
Database replication protocols based on group communication primitives have recently emerged as a promising technology to improve database fault-tolerance and performance. Roughly speaking, this approach consists in exploiting the order and atomicity prope ...
In a transactional system, an {\em atomic commitment} protocol ensures that for any transaction, all {\em Data Manager} processes agree on the same outcome {\em (commit} or {\em abort)}. A {\em non-blocking atomic commitment} protocol enables an outcome to ...
In a transactional system, an atomic commitment protocol ensures that for any transaction, all data managers agree on the same outcome: commit or abort. A non-blocking atomic commitment protocol enables an outcome to be decided at every correct data manage ...
Exploiting Atomic Broadcast in Replicated Databases F.Pedone, R.Guerraoui and A.Schiper Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distribute ...
This paper discusses the relationship between the {\em Non-\Blocking Atomic Commitment problem (NB-AC)} and the Consensus problem in asynchronous systems with {\em unreliable} failure detectors. We first confirm that NB-AC is harder than Consensus. In con ...
