Abstract

Conmutador de paquetes para una red con modo de transferencia asíncrono. El conmutador de paquetes para una red con modo de transferencia asíncrono es el elemento básico de una matriz de conmutación ATM, cuya misión es conmutar paquetes de 8, 12 ó 20 palabras de 4 bits, denominados microcélulas, organizados en tramas. Posee ocho entradas y cuatro salidas, por lo que para construir un elemento básico de conmutación de ocho entradas y ocho salidas se puentean las entradas de dos circuitos conmutadores de paquetes. Para la conmutación, en función de la cabecera de las microcélulas a la entrada, se encaminan a una salida determinada. Además evita pérdidas de información y problemas de contención de dichas microcélulas mediante un algoritmo de selección y colas a la salida del circuito conmutador. Posee también sincronización automática entre el reloj de los datos y el del sistema y detección de errores.
