RESUMO

Since its creation, Linux has brought attention to the open-source movement, and to the concrete possibility of using low cost solutions in critical mission systems. In the last years, this possibility has become real due to the creation of several high availability clusters. Today there are at least 10 open-source solutions and more than 25 commercial ones. Each one of these projects had a different approach to the problem, altought all of them had faced similar difficulties. If there was a standard in this area, efforts could be shared, and not duplicated. In this context, the Open Clustering Framework (OCF) is an open-source project that aims to define a cluster standard for Linux. One of the more important services in a cluster is the membership service. It is responsible for creating and maintaing the group. For this reason, it is important for many applications: high availability systems rely on this service to garantee the execution of the resources provided by a cluster. This thesis aims to present several concepts related to clusters, high availability and membership services. Having the concepts been defined, we will implement a membership service based on the OCF framework, in order to be able to incorporate this implementation in any OCF compliant cluster.
