Abstract

ESTA INVENCION SE REFIERE A UN METODO PARA ESTABLECER UNA CONEXION DE CONFERENCIA ENTRE VARIOS NODOS DE CONFERENCIA (2, 4, 8) QUE SE ENCUENTRAN EN UNA RED DE TELECOMUNICACION (1); Y TAMBIEN SE REFIERE A UN DISEÑO DE NODO (30; FIG. 3) DE TAL NODO DE CONFERENCIA. SEGUN ESTA INVENCION LA CONFERENCIA SE ESTABLECE EN BASE A UNA POR LLAMADA. CADA UNO DE LOS NODOS DE CONFERENCIA (2, 4, 8) ACCEDERAN, CADA VEZ QUE SE ACTIVA, A UNA FUENTE DE INFORMACION LIBRE (11) DE ENTRE MUCHAS FUENTES (11, 12..., N) Y TRANSMITIRA SU MENSAJE A ESTA FUENTE; MIENTRAS QUE , TODOS LOS NODOS DE CONFERENCIA DURANTE TODO EL TIEMPO QUE DURE LA CONFERENCIA, ESTAN ESCUCHANDO LOS MENSAJES QUE SE ENCUENTRAN EN TODAS LAS FUENTES ACTIVADAS U OCUPADAS. EL NUMERO MAXIMO DE NODOS DE CONFERENCIA ACTIVOS (EJ. TRANSMITIENDO) CORRESPONDEN AL NUMERO TOTAL DE FUENTES DE INFORMACION. EL NUMERO MAXIMO DE NODOS PASIVOS (EJ. ESCUCHA) ES ILIMITADO. UN NODO SE MUEVE NORMALMENTE DE UN ESTADO PASIVO A UNO ACTIVO Y VUELVE AL ESTADO PASIVO DEJANDODESOCUPADA LA FUENTE. ES PREFERIBLE QUE CADA FUENTE ESTE A MODO DE CONEXION EN BUCLE A TRAVES DE LA CUAL ESTAN INTERCONECTADAS TODOS LOS NODOS DE CONFERENCIA YA QUE EL BUCLE PASA POR LOS NODOS DE CONFERENCIA PASIVA EN CONEXION DERIVADA, PERO DONDE CADA CONEXION EN BUCLE ACTIVADA SE ROMPE, SOLO EN UN SITIO, PERO A MODO DINAMICO, A LA ENTRADA DEL NODO ACTIVO ASOCIADO A ESTE BUCLE UNICAMENTE, CUYO NODO ACTIVO ACCEDE A ESTA FUENTE PARTICULAR DURANTE EL PERIODO DE TIEMPO ACTIVADO DE SOLO ESTE NODO. LA INVENCION ES APROPIADO PARA CONFERENCIAS CRIPTO DIGITALES PUESTO QUE LOS MENSAJES SE DECODIFICAN Y DESCRIPTOGRAFIAN EN CADA ENTRADA DE NODO DE CONFERENCIA, MIENTRAS QUE LA ESCRIPTACION Y CODIFICACION DEL MENSAJE TIENEN LUGAR EN CADA SALIDA DEL NODO DE CONFERENCIA. ADEMAS, LA INVENCION SE PUEDE ADAPTAR FACILMENTE A LA RED DE DATOS DE MANTENIMIENTO INTEGRADA (RDMI). SE EVITAN TOTALMENTE LA ELIMINACION DE ECOS, ASI COMO LA ADICION Y SUSTRACCION DE SEÑALES DE CONFERENCIA. LAS REDAS CRIPTOGRAFICAS A UTILIZAR EN UNA CRIPTO CONFERENCIA DE ESTE TIPO, PUEDEN SER DISTRIBUIDAS ENTRE LOS NODOS QUE PARTICIPAN EN LA CONFERENCIA ANTES DE QUE COMIENCE LA CONFERENCIA; Y/O SE PUEDEN ALTERAR DURANTE LA CONFERENCIA, EN PAUSAS DE POCA DURANCION DE LA CONFERENCIA, O EN UNA FUENTE LIBRE, O VIA EL CANAL-D DE LA EJECUCION.
