Abstract
METODO PARA REGULAR EL TRAFICO DE CONTRAPRESION EN UNA RED DE CONMUTACION DE PAQUETES, COMPUESTO DE UNA PLURALIDAD DE ELEMENTOS CONMUTADORES, CADA UNO DE LOS CUALES TIENE UNA MEMORIA BUFFER LOCAL, QUE IDENTIFICA AL MENOS UN ELEMENTO DE CONMUTADOR, QUE SUCEDE A AL MENOS A OTRO ELEMENTO DE CONMUTADOR EN UNA TRAYECTORIA DE TRANSMISION. COMO MINIMO UNO DE LOS ELEMENTOS CONMUTADORES SUCESIVOS TIENE UNA MEMORIA BUFFER LOCAL CONGESTIONADA. SE TRANSMITE UNA SEÑAL DE CONTRAPRESION A AL MENOS OTRO DE LOS ELEMENTOS DE CONMUTADORES. LOS PAQUETES DESTINADOS AL ELEMENTO CONMUTADOR SUCESIVO HACEN COLA EN LA MEMORIA BUFFER LOCAL DE AL MENOS UNO DE LOS ELEMENTOS CONMUTADORES. A CONTINUACION, SE DETERMINA CUANDO LA OCUPACION DE LA MEMORIA BUFFER LOCAL, PARA EL OTRO ELEMENTO DE CONMUTACION, HA EXCEDIDO UN UMBRAL PREDETERMINADO. EN RESPUESTA AL UMBRAL PREDETERMINADO EXCEDIDO, EL OTRO ELEMENTO CONMUTADOR IGNORA LA SEÑAL DE CONTRAPRESION TRANSMITIDA DESDE EL ELEMENTO DE CONMUTACION SUCESIVO, Y TRANSMITE LOS PAQUETES DE LA COLA AL ELEMENTO DE CONMUTACION SUCESIVO.
