Abstract
Un método para sincronizar los nodos de una red de telecomunicaciones en la cual un nodo director se acopla a un Reloj de Referencia primaria (PRC) y multiples nodos subordinados se disponen para que sincronicen, cada uno, su reloj interno con el PRC, usando los datos recibidos en el enlace de datos entrante. El método comprende propagar los Mensajes de Estado de Sincronizacion a través de la red desde el nodo director, incorporando cada nodo a través del cual para un mensaje, su propia identidad dentro del mismo, generando así en cada mensaje una trayectoria seguida por él. En cada enlace entrante de cada nodo, se registra la trayectoria o longitud de trayectoria de una Mensaje de Estado de Sincronizacion recibido en ese enlace, como un atributo del mismo.
