Abstract

L'invention concerne des réseaux en anneau fonctionnant selon la norme de transmission par réseau optique synchrone (SONET), qui partagent au moins une ligne de protection. L'information d'identification et de disponibilité de la ligne de protection partagée est répartie entre les commutateurs des réseaux en anneau de la norme SONET, via des données à octet K qui sont incorporées aux bits de service de cette norme.
