In many Internet scale replicated system, not all
replicas can be dealt with in the same way, since some will
be in greater demand than others. In the case of weak
consistency algorithms, we have observed that updating
first ...

Communication latencies have been identified as one of the
performance limiting factors of message passing applications in clusters of
workstations/multiprocessors. On the receiver side, message-copying operations
contribute ...

Web caching is a technology that has demonstrated to
improve traffic on the Internet. To find out how to
implement a Web caching architecture that assures
improvements is not an easy task. The problem is more
difficult ...
Decentralized resource allocation in application layer networks

Application-layer networks (ALN) are software
architectures that allow the provisioning of services
requiring a huge amount of resources by connecting large
numbers of individual computers. The ALN simulation
project ...
