Adaptando as Especificações FT-CORBA para Redes de Larga Escala

Lau Cheuk LungJoni da Silva FragaRicardo PadilhaLuciana Souza

This work presents a proposal to extend the Fault-Tolerant CORBA specifications [OMG00] to large-scale distributed systems. Our motivations for this proposal are that FT-CORBA does not assist, properly, to the requirements of fault-tolerant in large-scale networks, such as Internet. In this paper, we present a set of solutions (including failure detection, membership, group communication) that aim, mainly, to treat scalability aspects in large-scale network. The main contribution of this paper is the proposal of a model of hierarchy to fault tolerance domains, which facilitates the management and communication for inter-domain groups.
