Abstract

Un sistema y método para la distribución de datos a través de una pluralidad de nodos de almacenamiento remoto. Los datos se dividen en segmentos y cada segmento se codifica en una serie de fragmentos de palabras de código. Ninguno de los fragmentos de palabras de código contiene alguno de los segmentos. Cada fragmento de palabra de código esta empaquetado con al menos un parámetro de codificación y el identificador, y los metadatos se generan para al menos un archivo y para los segmentos relacionados de por lo menos un archivo. Los metadatos contienen información para reconstruir a partir de los segmentos, y la información para la reconstrucción de los paquetes correspondientes. Además, los metadatos se codifican en paquetes, y corresponden a un nivel de seguridad respectivo y una protección contra el fallo del nodo de almacenamiento. Una pluralidad de paquetes está asignada a nodos de almacenamiento remotos para optimizar la distribución de carga de trabajo. Cada uno de los paquetes se transmite a por lo menos un nodo de almacenamiento respectivo como una función de acceso iterativo y recuperación de los paquetes de metadatos y datos de archivo.
