Multiple Heterogeneous Ant Colonies with Information Exchange

Arash Arami, Bijan Rahimzadeh Rofoee

The method of multiple heterogeneous ant colonies with information exchange (MHACIE) is presented in this paper with emphasis on the speed of finding the optimal solution and the corresponding computational complexity. The proposed method which is inspired ...

Modeling and validating the performance of atomic broadcast algorithms in high-latency networks

André Schiper, Nils Richard Ekwall

The performance of consensus and atomic broadcast algorithms using failure detectors is often affected by a trade-off between the number of communication steps and the number of messages needed to reach a decision. In this paper, we model the performance o ...

Atomic broadcast

Nils Richard Ekwall

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 ...

A Formal Analysis of the Deferred Update Technique

Rodrigo Malta Schmidt, Fernando Pedone

The deferred update technique is a widely used approach for building replicated database systems. Its fame stems from the fact that read-only transactions can execute locally to any single database replica, providing good performance for workloads where tr ...

A Primary-Backup Protocol for In-Memory Database Replication

Rodrigo Malta Schmidt, Fernando Pedone

The paper presents a primary-backup protocol to manage replicated in-memory database systems (IMDBs). The protocol exploits two features of IMDBs: coarse-grain concurrency control and deferred disk writes. Primary crashes are quickly detected by backups an ...

Network Correlated Data Gathering with Explicit Communication: NP-Completeness and Algorithms

Martin Vetterli, Razvan Cristescu

We consider the problem of correlated data gathering by a network with a sink node and a tree based communication structure, where the goal is to minimize the total trans- mission cost of transporting the information collected by the nodes, to the sink nod ...

Comparing Atomic Broadcast Algorithms in High Latency Networks

André Schiper, Nils Richard Ekwall

Since the introduction of the concept of failure detectors, several consensus and atomic broadcast algorithms based on these detectors have been published. The performance of these algorithms is often affected by a trade-off between the number of communica ...

Multicoordinated Paxos

Rodrigo Malta Schmidt, Fernando Pedone

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 ...
