Abstract

ESTA INVENCION SE REFIERE A UN METODO Y APARATO PARA TRANSMITIR TRAFICOS DE NIVEL DE BITS CONSTANTES Y VARIABLES EN UN CONMUTADOR ISDN DE BANDA ANCHA. LOS DATOS DE FUENTES DE NIVEL DE BITS CONSTANTES TALES COMO CAMARAS DE TELEVISION, SE INTRODUCEN EN UN GRUPO DE COLAS (134, 136, 138, 139). CADA MIEMBRO DEL GRUPO PARA QUE PONGA EN LINEA LOS DATOS DE UNA DIFERENTE BANDA DE NIVELES DE BITS. LOS DATOS SE TRANSMITEN DESDE ESTAS COLAS CON LA MAS ALTA PRIORIDAD DESDE LA COLA QUE ALMACENA LOS DATOS DE LA BANDA MAS ALTA DE NIVELES DE BITS. SI LA ENTIDAD ALINEADA MAS LARGA DE DATOS EN UNA DE LAS OTRAS COLAS HA SIDO ALINEADA PARA MAS DE UN PERIODO PRE-ESPECIFICADO, SU PRIORIDAD AUMENTA. ESTUDIOS ANALITICOS HAN DEMOSTRADO QUE LA UTILIZACION DE TRES COLAS PARA EL TRAFICO CONSTANTE DE NIVEL DE BITS Y UNA CUARTA COLA PARA EL TRAFICO VARIABLE DE NIVELES DE BITS, PERMITE UNA ALTA OCUPACION DE LOS CANALES DE SALIDA PARA QUE SE MANTENGA CON UN NUMERO INSIGNIFICANTE DE ENTIDADES DE DATOS EXCESIVAMENTE RETRASADOS.
