Abstract

UNA DISPOSICION DE RED DE COMUNICACION DE DATOS. LA BASE DE DATOS EMPLEADA INCLUYE AL MENOS DOS UNIDADES BASE DE DATOS, SEPARADAS GEOGRAFICAMENTE Y CONECTADAS A TERMINALES DE DATOS POR UNA RED DE TELECOMUNICACIONES. CADA UNIDAD BASE, ESTA CONECTADA AL MENOS A UNO DE LOS NUDOS DE CONEXION DE LA RED, PROVISTOS DE SELECTORES DE VIA DE TRANSMISION, E INCLUYE UN TRANSMISOR/RECEPTOR DE ACTUALIZACION CONECTADO A TRAVES DE CONEXIONES PERMANENTES ESTABLECIDAS AL TRANSMISOR/RECEPTOR DE ACTUALIZACION DE OTRAS UNIDADES BASE DE DATOS. LAS UNIDADES BASE INCLUYEN MEDIOS SELECTORES QUE GENERAN SEÑALES DE IDENTIFICACION PARA SELECCIONAR COMO UNIDAD EJECUTIVA UNA DE LAS UNIDADES BASE INDIVIDUALMENTE. LA SEÑAL DE IDENTIFICACION GENERADA ALEATORIAMENTE ES TRANSMITIDA AL MENOS A LA UNIDAD BASE DE DATOS SELECCIONADA COMO EJECUTIVA PARA INICIAR EL FUNCIONAMIENTO DE SUS MEDIOS SELECTORES Y DEL TRANSMISOR DE ACTUALIZACION Y A TODOS LOS SELECTORES DE VIA DE TRANSMISION DE LA RED QUE ESTAN CONTROLANDO EL TRAFICO DE LLAMADAS DESDE LOS TERMINALES DE DATOS HASTA LA UNIDAD EJECUTIVA.
