Abstract

En un sistema de conmutacion de banda amplia para la conmutacion de celdas asíncronamente de datos, un controlador de ancho de banda dinámico (DBC) controla la aplicacion de celdas de datos a una puerta de entrada del sistema, las celdas de datos que son suministradas por un numero de sistema de terminacion de transmision. Cuando un sistema de terminacion empieza a transnmitir celdas de datos, el DBC detecta la presencia de celdas entrantes y solicita el ancho de banda desde un control de admision de conexion (CAC) que forma parte del sistema. El sistema de conmutacion almacena una tabla que asocia un numero de fuentes de señal conectadas a la puerta de entrada con tiempos de transmision máximo predeterminados y relaciones de transmision máximas para las fuentes. Cuando la llegada de celdas en la puerta de entrada desde una de la fuente es detectada, los DBC y CAC operan juntos para asignar suficiente ancho de banda en el sistema de conmutacion para permitir que el tamaño de mensaje respectivo sea transmitido dentro del tiempo de transmision máximo respecyivo. Una relacion mínima garantizada de transmision se garantiza también
