Nowadays, networked computers are present in most aspects of everyday life. Moreover, essential parts of society come to depend on distributed systems formed of networked computers, thus making such systems secure and fault tolerant is a top priority. If t ...
It is noticeable that our society is increasingly relying on computer systems. Nowadays, computer networks can be found at places where it would have been unthinkable a few decades ago, supporting in some cases critical applications on which human lives ma ...
This paper presents a mechanism allowing an ODP compliant distributed system, ANSA, to access OSI network management objects as if they were ANSA objects. It defines a mapping from the OSI object model to the ANSA object model, and it specifies how an adap ...
Directory services are a genuine constituent of any distributed architecture which facilitate binding attributes to names and then querying this information, i.e., announcing and discovering resources. In the web services domain this functionality is provi ...
It has been widely recognised that matchmaking is an important component of heterogeneous multiagent systems. Several researchers have developed powerful techniques for the matchmaking problem in general. There are also specific representation of agent cap ...
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 ...
This paper presents x-ability (Exactly-once-ability): a correctness criteria for replicated services. X-ability provides the illusion that the actions executed by a replicated service are executed exactly-once, even if these actions have been actually exec ...
Replication is a key mechanism for developing fault-tolerant and highly available applications. In this paper, we present a replication framework for replicating CORBA objects, that combines the active and passive replication techniques. We show how we hav ...
The Swiss Exchange system (SWX system) was the first stock exchange system in service to be fully computerised. For high availability, the trading system is built as a replicated service based on Isis. For portability reasons, the SWX team has considered b ...
Directory services are a genuine constituent of any distributed architecture which facilitate binding attributes to names and then querying this information, that is, announcing and discovering resources. In such contexts, especially in a business environm ...
