Abstract
Sistema, dispositivo y método para compartir miniintervalos de contención entre clases múltiples de prioridad que determina un estado de realimentación global para cada una de las clases de prioridad, determina una asignación preferida de miniintervalos de contención para cada una de la pluralidad de las clases de prioridad utilizando un estado de realimentación global, y determinar una asignación real de miniintervalos de contención para cada una de la pluralidad de clases de prioridad empleando la asignación preferida. La asignación real de miniintervalos de contención se determina haciendo un asignación preliminar para cada una de las clases de prioridad en base de la asignación preferida y asignando después los miniintervalos de contención restantes entre las clases de prioridad.
