Abstract

Patente de Invenção. "SISTEMA DE DUTO DE COMUNICAçãO DE MULTIESTAçõES E ESTAçãO MESTRE PARA USO NO MESMO". Um sistema de duto de comunicação de multiestações acomodar estações mestre e estações escravo, e arbitragem baseada em quadro entre estações mestre . O quadro é formatado mediante um resultado favorável da arbitragem transmitindo um mensagem organizada em quadros inclusive sinalizações de bloqueio e desbloqueio para bloquear e desbloquear respectivamente, uma estação escravo endereçada por uma duração de múltiplos quadros da mensagem. Isto bloqueia uma estação mestre diferente contra o acesso a uma estação escravo bloqueada durante esta duração. Além disso, a estação mestre diferente ao detectar a condição bloqueada executa um primeira seq³ência de ações de reenvio relativamente freq³entes em um período de tempo combinado que é substancialmente menor que um valor máximo padrão da dita duração. A seguir segue-se, se requerida, uma segunda seq³ência de ações de reenvio relativamente infreq³entes num período de tempo combinado que é maior que o valor máximo padrão da duração.
