Abstract

UN FALLO POTENCIAL DE ACCESO-TRANSMISION EN EL PROTOCOLO IEEE 802.6 SE SOLUCIONA POR EL USO DE TERMINALES QUE DETERMINAN EL NIVEL DE ACTIVIDAD EN LAS LINEAS QUE INTERCONECTAN COMUNICACIONES. EN RESPUESTAS A CONDICIONES QUE PUEDAN HACER SURGIR TAL FALLO, CADA TERMINAL MODERA SU TASA DE TRANSMISION PARA MEJORAR LA ASIGNACION DE CAPACIDAD DE TRANSMISION DE PROTOCOLO. EN UNA REALIZACION, EL TERMINAL QUE TRANSMITE A TRAVES DE MAS DE LA MITAD DE LAS RANURAS EN LA SEGUNDA VUELTA SIMPLEMENTE SE MODERA HASTA LA MITAD DE LAS RANURAS CUANDO DETECTA QUE OTRO ESTA TRANSMITIENDO O DESEA TRANSMITIR. EN OTRA REALIZACION INCLUSO UN TERMINAL QUE ESTA TRANSMITIENDO A TRAVES DE MENOS DE LA MITAD DE LAS RANURAS EN LA DEMORA DE SEGUNDA VUELTA DETERMINA EL NUMERO DE RANURAS SIN OCUPAR Y SE MODERA HASTA TRANSMITIR A TRAVES DE NO MAS DE LA MITAD DEL NUMERO DE RANURAS DISPONIBLES. EN OTRA REALIZACION, UN TERMINAL DESEOSO DE TRANSMITIR MUCHOS PAQUETES ENCAPSULA UN NUMERO DE BITS DE RESERVA SOBRE EL CANAL DE TRANSMISION PARA ASEGURARSE ALGUNA CAPACIDAD DE TRANSMISION. EL NUMERO DE BITS DE RESERVA ENVIADO ES IGUAL A UNA FRACCION DE LAS RANURAS DISPONIBLES. Y AUN EN OTRA REALIZACION, CADA TERMINAL SE MODERA PARA NO TOMAR MAS DE UNA FRACCION ESPECIFICA DE LA CAPACIDAD DE TRANSMISION QUE QUEDA.
