Abstract

<B>MéTODO E APARELHO PARA PROCESSAMENTO DE CHAMADA COM TOLERâNCIA DE FALHA<D> Um método e aparelho para processar dados de chamada. Um primeiro servidor no modo ativo replica dados de chamada para um segundo servidor de modo reserva. O primeiro servidor é monitorado para uma condição de falha pelo segundo servidor, bem como outros dispositivos de rede. Caso seja detectada uma condição de falha, o primeiro servidor é comutado para o modo reserva e o segundo servidor para o modo ativo.
