Abstract

Un sistema (100) de red de comunicaciones, que comprende cuando menos tres nodos, los cuales se interconectan por enlace (110) de transmision, que llevan tráfico hacia y desde los nodos. Estos enlaces (110) de transmision se dividen en un anillo de trabajo (112) y un anillo de proteccion (114), donde el anillo de trabajo (112) y el anillo de proteccion (114) pueden transmitir el tráfico en direcciones opuestas. Un nodo es capaz de detectar cuando ocurre un error en el ambiente intermedio, los enlaces de transmision (110) o el nodo. Cada nodo puede por sí mismo desviar el tráfico desde el anillo de trabajo (112) al anillo de proteccion (114) y/o por sí mismo desviar el tráfico desde el anillo de proteccion (114) al anillo de trabajo (112). Se realiza una accion de recuperacion cuando se repara el error.
