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 ...

Given the increasing popularity of real-time video communication over enterprise wireless networks, ensuring good quality of experience is becoming critical. A common problem in such networks is that the clients typically adopt the strategy of associating ...

Designing and correctly implementing Group Communication Systems (GCSs) is notoriously difficult. Assuming that processes fail only by crashing provides a powerful means to simplify the theoretical development of these systems. When making this assumption, ...

Modularity is a desirable property of complex software systems, since it simplifies code reuse, verification, maintenance, etc. However, the use of loosely coupled modules introduces a performance overhead. This overhead is often considered negligible, but ...

Protocol composition frameworks provide off-the-shelf composable protocols to simplify the development of custom protocol stacks. All recent protocol frameworks use a general-purpose event-driven model to manage the interactions between protocols. In compl ...

Atomic broadcast in particular, and group communication in general, have mainly been specified and implemented in a system model where processes do not recover after a crash. The model is called crash-stop. The drawback of this model is its inability to ex ...

Atomic broadcast is a useful abstraction for implementing fault-tolerant distributed applications such as state-machine replication. Although a number of algorithms solving atomic broadcast have been published, the problem of bounding the memory used by th ...
