Abstract

UNA RED DE COMUNICACIONES DISTRIBUTIVA COMPRENDE GRUPOS DE NODOS (11 - 22, 31 - 36, 41 - 43, 51) A DIFERENTES NIVELES (1, 2, 3, 4). CADA GRUPO DE NODOS A UN NIVEL ESTA CONECTADO A UN NODO ASOCIADO EN EL NIVEL SUPERIOR PARA LA TRANSMISION Y RECEPCION DE TRAFICO. EL TRAFICO SE ASIGNA A UNO DE UN NUMERO DE BANDAS O LONGITUDES DE BANDA DE ACUERDO A SI ES UN TRAFICO DE AREA LOCAL O MAS EXTENSO. EN EL PRIMER NIVEL DE NODOS (11 - 22) EL TRAFICO DE AREA LOCAL EN LA BANDA CORRESPONDIENTE DE LONGITUDES DE ONDA SE RECICLA Y SE RETRANSMITE A TODOS LOS TERMINALES (A - X) QUE ESTAN CONECTADOS A ESE NODO. EN CADA NIVEL DE NODOS, EL TRAFICO SE PASA ASI A OTRO NIVEL SUPERIOR O SE RECICLA DE ACUERDO A LA BANDA DE LONGITUDES DE ONDAS A LAS CUAL ESTA ASIGNADO. ASI, LA BANDA DE LONGITUDES DE ONDA DETERMINA EL NIVEL DEL NODO EN EL QUE EL TRAFICO SE RECICLA, Y LA TOLERANCIA DE LOS TERMINALES EXPUESTOS ULTIMAMENTE A ESTE TRAFICO. ES POSIBLE REUTILIZAR BANDAS DE LONGITUDES DE ONDA PARA COMUNICACION ENTRE LOS TERMINALES.
