Abstract

Un aparato conmutador para una disposicion de comunicaciones que emplea tecnología de Modo de transferencia Asincronico (ATM), un recurso de puesta en colade espera brinda una puesta en cola de espera centralizada para células ATM destinadas para ruteo a través del nucleo conmutador ATM a diversos enlaces desalida. Un método para operar dicho aparato, el nucleo conmutador ATM rutea una célula ATM destinada para cualquier enlace de salida que requiere puesta encola de espera al recurso de puestaen cola de espera centralizado. Células ATM para enlaces de salida que no requieren puesta en cola de espera no se dirigenal recurso de puesta en cola de espera. La puesta en cola de espera se realiza con respecto a las células ATM en el recurso depuesta de cola en esperacentralizado, y entonces las células ATM son ruteadas a través del nucleo conmutador ATM a un enlace de salida. El recurso de puesta en cola de espera tieneun multiplexor de enlace (280) para cada enlace de salida que maneja por el recurso de puesta en cola de espera. Cada multiplexor de enlace tiene tanto unaprimera etapa (304) como una segunda etapa (302). La segunda etapa comprende diversas colas de espera (312 para almacenar paquetes ATM y un multiplexor (314)de segunda etapa para seleccionar los paquetes ATM almacenados en las diversas colas de espera de la segunda etapa para su transmision a la primera etapa. Laprimera etapa comprende diversas colas de espera (320) para almacenar células ATM y un multiplexor(330) de primera etapa para seleccionar las células ATMmultiplexadas de la segunda etapa para descargar del recurso de puesta en cola de espera. El recurso de puesta de cola en espera centralizado y selectivo obviala necesidad de poner en cola de espera en cada tablero terminal conectado al nucleo conmutador ATM.A switching device for a communications arrangement employing Asynchronous Transfer Mode (ATM) technology, a queuing queuing resource provides centralized queuing for ATM cells intended for routing through the ATM switching core to various links desalida One method of operating said apparatus, the ATM switching core routes an ATM cell destined for any output link that requires queuing to the centralized queuing resource. ATM cells for outbound links that do not require queuing are not directed to the queuing resource. Queuing is performed with respect to the ATM cells in the queued de-centralized queue resource, and then the ATM cells are routed through the ATM switching core to an outbound link. The queuing resource has a link multiplexer (280) for each output link that it handles by the queuing resource. Each link multiplexer has both a first stage (304) and a second stage (302). The second stage comprises various queues (312 for storing ATM packets and a second stage multiplexer (314) for selecting the ATM packets stored in the various queues of the second stage for transmission to the first stage. The first stage comprises various queues (320) for storing ATM cells and a first stage multiplexer (330) for selecting the multiplexed ATM cells of the second stage for downloading from the queuing resource. The centralized queuing resource and Selectively obviates the need to queue on each terminal board connected to the ATM switching core.
