Abstract
UNA RED DE COMUNICACIONES COMPRENDE UNA PLUIRALIDAD DE ESTACIONES, LAS CUALES PUEDEN COMUNICAR A TRAVES DE UN ANILLO. LA INFORMACION ES TRANSMITIDA DESDE UNA ESTACION A OTRA EN BLOQUES DE MENSAJE, LOS CUALES CIRCULAN ALREDEDOR DEL ANILLO. LOS BLOQUES DE MENSAJE INCLUYEN BITS DE CONTROL Y UN PROTOCOLO ES EMPLEADO, EL CUAL ASEGURA QUE NINGUNA ESTACION PUEDE MONOPOLIZAR LOS BLOQUES DE MENSAJE DISPONIBLES. EN CUALQUIERA DE LAS ESTACIONES, UN BLOQUE VACIADO ES UTILIZADO POR LA ESTACION COMO UN HUECO DE PRUEBAS DE RECOLOCACION Y COLOCA SU PROPIA DIRECCION DENTRO, PARA PASAR ALREDEDOR DEL ANILLO. SOBRE SU REGRESO, UN SISTEMA RESTABLECE SU INSTIGACION, PARA PERMITIR QUE TODAS LAS ESTACIONES SEAN RECOLOCADAS EN BLOQUES "D".
