Abstract

Para proporcionar una corriente saliente correcta de paquetes de datos para cada conexión establecida (que tienen números de identificación vc/vp) en un conmutador de paquete de datos (1), que comprende varios planos de conmutación paralelos, que son idénticos entre sí, hay cuatro portillos de salida (5) para cada plano de conmutación (No. 1 y 2) y cada conexión establecida incluye una memoria intermedia (29) dispuesta para almacenar por lo menos un paquete de datos. Cuando un primer paquete de datos llega a un portillo de salida (5) éste se prueba inmediatamente mediante un dispositivo control (26, 35) para este portillo de salida, si este primer paquete de datos es el siguiente paquete de datos, que a su vez va a enviarse desde el conmutador (1). En un primer caso, cuando esa condición se satisface, el paquete de datos es enviado desde el conmutador (1). En un segundo caso, cuando esta condición no se satisface, el paquete de datos se almacena en la memoria intermedia (29) que se dispone para conectarse al paquete de datos que pertenece, y para el plano de conmutación a través del cual ha viajado el paquete de datos.
