Abstract
Se revelan varias modalidades para compensar la deriva del reloj entre nodos de una red síncrona en el tiempo. Un nodo recibe información de sincronización de tiempo de un nodo padre en la red. Se determina una deriva entre un reloj del nodo y un reloj del nodo padre, en base a la información de sincronización de tiempo. El nodo identifica un número de intervalos de tiempo de la red desde la ejecución de una última sincronización de tiempo, en base a información de sincronización de tiempo previa transmitida del nodo padre. Se calcula un intervalo de compensación que representa un número de intervalos de tiempo en los cuales el reloj del nodo se desvió, con respecto al nodo padre, por un valor de compensación predefinido. El nodo compensa, por el valor de compensación, uno de los intervalos de tiempo de acuerdo con el intervalo de compensación.
