Abstract

ESTA RED LOCAL DE TRANSMISION COMPRENDE VARIAS ESTACIONES (S1...S4) CONSTITUIDAS CADA UNA POR UNA MAQUINA INFORMATICA (M) ACOPLADA A UN INTERFAZ (IR) DE EMISION-RECEPCION RADIO (IRP, IRE). CADA MAQUINA INFORMATICA COMPRENDE UN ACOPLADOR (CE) PARA EMITIR UN MENSAJE QUE CONTIENE UNA DIRECCION QUE REPRESENTA UNA ESTACION DESTINATARIA Y PARA RECIBIR MENSAJES QUE SE SON DIRIGIDOS. LA RED COMPRENDE ADEMAS UN REPETIDOR (R) QUE COMPRENDE UN INTERFAZ DE EMISION-RECEPCION RADIO (IRE'', IRR''), ACOPLADO A UN CABLE RADIANTE (CR) QUE PASA CERCA DE TODAS LAS ESTACIONES, PARA RECIBIR TODOS LOS MENSAJES EMITIDOS POR LAS ESTACIONES, MODIFICAR ESTOS MENSAJES, INDICANDO ESTA MODIFICACION QUE EL MENSAJE HA TRANSITADO POR EL REPETIDOR; Y A CONTINUACION REEMITIR ESTOSMENSAJES SOBRE EL CABLE RADIANTE. EL INTERFAZ DE EMISION RECEPCION RADIO (IRR, IRE) DE CADA ESTACION COMPRENDE MEDIOS (37) PARA NO TOMAR EN CUENTA MAS QUE LOS MENSAJES QUE HAN SIDO EMITIDOS POR EL REPETIDOR (R). APLICACION EN REDES LOCALES DE MAQUINASINFORMATICAS.
