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 ...
Distributed systems are the basis of widespread computing facilities enabling many of our daily life activities. Telebanking, electronic commerce, online booking-reservation, and telecommunication are examples of common services that rely on distributed sy ...
A distributed algorithm comprises a collection of sequential-code entities, which are spread over different computers connected to a network. The process of designing a distributed algorithm is influenced by the assumptions we make on the computational env ...
Concurrency and failures are fundamental problems in distributed computing. One likes to think that the mechanisms needed to address these problems can be separated from the rest of the distributed application: in modern words, these mechanisms could be as ...
The well-known Fusion object-oriented methodology is restricted to the development of sequential systems and certain restricted kinds of concurrency systems. Consequently, the development of distributed systems is only possible wiht additions and fixes to ...
A few years ago, a perceptually-tuned grayscale character generation technique was developed in order to automatically synthesize grayscale characters looking like manually-tuned pixmap characters. Weight and contrast controlled grayscale characters are ob ...
It is now recognized that the Consensus problem is a fundamental problem when one has to design and implement reliable asynchronous distributed systems. This chapter is on the Consensus problem. It studies Consensus in two failure models, namely, the Crash ...
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 ...
The following dissertation addresses one aspect of cooperative editing which has not been well examined until now : the consideration of hardware limitations imposed by a large scale distributed system (namely the Internet). This system model implies heter ...
