RESUMO

The aim of this work has been the implementation of a group communication system, that will be the base for development of other subsystems of the Xchart Environment. The Xchart Environment provides a set of tools for specification and implementation of concurrent human-computer interfaces, interfaces that may be divided in many sub-interfaces. Each sub-interface may be run in a different computer of a distributed system. Thus, an environment to control the distributed execution of the sub-interfaces, named Distribution Manager, is needed. This work implements the lowest level subsystem of the Distribution Manager, and it is composed of the following modules: Communication System (responsible for the exchange of messages with the distributed system), Failure Detection System (it detects failures in the communication and notifies the Communication System), Group Server (responsible for keeping groups and for multicast sending for a group of processes), and Name Server (it provides location transparency of shared resources of a distributed system)
