Abstract

"MéTODO PARA RECONSTRUçãO DE PACOTES PERDIDOS E DISPOSITIVO PARA REALIZAR O DITO MéTODO". A invenção proporciona um método para assegurar um fluxo de pacotes de dados, o dito método compreendendo as etapas de ordenar os pacotes para transmissão em uma matriz de D linhas e L colunas, aplicar uma função de correção de erro para cada linha e coluna, cujo resultado é um pacote de correção, e transmitir os pacotes de correção resultantes em adição aos pacotes de dados. A dita invenção também se relaciona com um método para a reconstrução de pacotes perdidos em um fluxo de pacotes de dados, o dito método compreendendo as etapas de ordenar os pacotes recebidos em uma matriz de D linhas e L colunas, de acordo com o número de seqüência dos mesmos, e aplicar uma função de reconstrução de pacotes perdidos para cada linha e coluna da matriz contendo pelo menos um pacote perdido, a dita função utilizando os pacotes recebidos e os pacotes de correção correspondendo a linha ou coluna. A invenção também se relaciona com dispositivos para realizar os ditos métodos.
