The term distributed Consensus denotes the problem of getting a certain number of processes, that could be far away from each other and that exchange messages through some communication means, to all agree on the same value. This problem has been proved im ...
Within only a couple of generations, the so-called digital revolution has taken the world by storm: today, almost all human beings interact, directly or indirectly, at some point in their life, with a computer system. Computers are present on our desks, co ...
Improving the dependability of computer systems is a critical and essential task. In this context, the paper surveys techniques that allow to achieve fault tolerance in distributed systems by replication. The main replication techniques are first explained ...
In this paper, we present a novel architecture to support large scale stream processing services in a widely distributed environment. The proposed system, COSMOS, distinguishes itself by its loose coupling and communication efficiency. To exploit the shari ...
Classic Paxos is a round-based distributed consensus algorithm. Normally, proposals are sent to the round leader and decided in two communication steps more. Fast Paxos extends Classic Paxos by allowing also fast rounds, in which a decision can be learned ...
Nowadays, computers are the indispensable part of our life. They evolve rapidly and are more and more versatile. Computer networks made the remote corners of the world just a click away. But unavoidably, any software and hardware component is subject to fa ...
We consider the problem of correlated data gathering by a network with a sink node and a tree communication structure, where the goal is to minimize the total transmission cost of transporting the information collected by the nodes, to the sink node. Two c ...

The communication between avatar and agent has already been treated from different but specialized perspectives. In contrast, this paper gives a balanced view of every key architectural aspect: from text analysis to computer graphics, the chatting system a ...
Composability and deadlock-freedom are important properties that are stated for transactional memory (TM). Commonly, the Semantics of TM requires linearization of transactions. It turns out that linearization of transactions that have cyclic communication ...
An indulgent algorithm is a distributed algorithm that, besides tolerating process failures, also tolerates unreliable information about the interleaving of the processes. This article presents a general characterization of indulgence in an abstract comput ...
