Abstract

UN DISPOSITIVO DE RESECUENCIAMIENTO PARA UN NUDO DE UN SISTEMA DE CONMUTACION DE CELULAS INCLUYE EN PARTICULAR: UN GENERADOR (TSG) DE ETIQUETAS TEMPORALES, PARA ATRIBUIR UNA ETIQUETA TEMPORAL A CADA CELULA, UNA MEMORIA TAMPON (BM), UNA MEMORIA DE DIRECCIONES (FSAM) PARA MEMORIZAR LA DIRECCION DE LA PRIMERA SUBCELULA DE DIRECCION DE LA MEMORIA TAMPON QUE CONTIENE LA PRIMERA SUBCELULA DE UNA CELULA. ESTE CIRCUITO INCLUYE EN PARTICULAR: UNA MEMORIA ACCESIBLE POR EL CONTENIDO, PARA MEMORIZAR IDENTIFICADORES DE CELULAS EN ESPERA, CONSTITUIDOS CADA UNO POR LA IDENTIDAD DE UN INTERVALO DE TIEMPO DONDE EXPIRA EL PLAZO DE ESPERA DE LA CELULA, Y POR LA IDENTIDAD DE AL MENOS UNA SALIDA DONDE LA CELULA DEBE SER EMITIDA; Y UNA MEMORIA DE COLA PARA CADA SALIDA, DONDE ESTA INSCRITO UN NUMERO DE ORDEN CADA VEZ QUE UN PLAZO DE ESPERA EXPIRA PARA AL MENOS UNA CELULA QUE DEBE SER EMITIDA SOBRE ESTA SALIDA; CADA MEMORIA DE COLA ES DEL TIPO ACCESIBLE POR EL CONTENIDO, Y LOS NUMEROS ESTAN BUSCADOS EN EL ORDEN CRECIENTE, CUANDO ESTA SALIDA ESTA DISPONIBLE.
