Exploiting virtual synchrony in distributed systems

K. Birman, T. Joseph
1987 ACM SIGOPS Operating Systems Review  
Virtual synchrony in distributed systems What makes the problems of synchronization, consistency and failure detection hard to tackle in a distributed setting is the asynchronous propagation of information  ...  Similarly, virtual synchrony can be exploited to determine the sequence of site and process failures that occurred while a site was down.  ...

A Study on Substrate Network Synchrony Demands to Support Hybrid Synchrony Virtual Networks

Rasha Hasan, Odorico Machado Mendizabal, Romulo Reis de Oliveira, Fernando Luis Dotti
2014 2014 Brazilian Symposium on Computer Networks and Distributed Systems  
In this sense, Hybrid Synchrony Virtual Networks (HSVN) has been proposed to fulfil specific synchrony requirements and better support a considerable class of distributed systems.  ...  Network virtualization has been proposed in the last years, and it received special attention from both networking and distributed systems communities.  ...  In that model the degree of synchrony varies over time. In [7] , Veríssimo presented the wormhole model, that also exploits the space dimension to provide hybrid synchrony.  ...

Building reliable distributed systems with CORBA

Sean Landis, Silvano Maffeis
1997 Theory and Practice of Object Systems  
CORBA mainly deals with pointto-point communication and o ers no support for the development of reliable applications that exhibit predictable behavior in distributed systems.  ...  In this paper we present extensions to CORBA which provide group communication, reliability, and fault-tolerance.  ...  This type of operation fully exploits the multiprocessing capabilities available in a distributed system.  ...

Support of Strong Consistency on Fog Applications

Diogo Lima, Hugo Miranda, François Taïani
2019 Proceedings of the 6th Workshop on Principles and Practice of Consistency for Distributed Data - PaPoC '19  
This paper addresses how virtual synchrony, in particular a technique named Light-Weight Group (LWG), can help supporting strong consistency for mobile applications in the Fog Computing environment.  ...  Providing scalability for mobile distributed applications often leads the applications to compromise their consistency requirements.  ...  To achieve such goal, we rely on virtual synchrony [1] . Virtual synchrony organizes processes into groups.  ...
