Abstract

Procedimiento y dispositivo de dirección para una red de comunicaciones conmutadas en paquetes, consistente en m nodos controlados por un ordenador, en base de la inspección de la longitud de las filas de espera y, de un modo más particular de la estimación derivativa de un flujo de paquetes con respecto al retardo presentado por dichos paquetes en las filas de espera, caracterizado el procedimiento porque el encauzamiento o dirección óptimo de los paquetes se obtiene por las operaciones siguiente en secuencia-actualización de las tablas de itinerarios del nodo simple, en base de la estimación de retardo en las n+1 filas de espera del nodo, y en base también de la información en el estado de la red, almacenada en el ordenador de dicho nodo.
