Abstract

"MéTODO E SISTEMA PARA ENCAPSULAMENTO DE PACOTES". O encapsulamento de pacotes compreende o recebimento de pacotes numa fila de um encapsulador. As operações subseq³entes são repetidas até que sejam satisfeitos determinados critérios. Um número de pacotes é acumulado na fila. Uma eficiência de encapsulamento corrente, associada aos pacotes acumulados, é determinada. Uma eficiência de próximo encapsulamento, associada aos pacotes acumulados e a uma previsão de próximo pacote, é determinada. Se o encapsulamento corrente satisfizer um limite mínimo de eficiência de encapsulamento e se a eficiência de encapsulamento corrente for maior do que a eficiência do próximo encapsulamento, os pacotes acumulados são encapsulados. Caso contrário, os pacotes continuam a ser acumulados na fila.
