Abstract

método de notificação de erro de bit e dispositivos associados. a presente invenção refere-se a método de notificação de erro de bit e dispositivos associados (nós; e produto de computador). o método compreende: um nó intermediário em um primeiro terminal detecta que uma taxa de erro de bit de um pacote enviado através do primeiro túnel excede um limite; o nó intermediário envia um primeiro pacote para um nó de saída do primeiro túnel através do primeiro terminal, e o primeiro pacote é usado também para indicar que um erro de bit ocorreu no primeiro túnel, no qual o primeiro pacote é ainda usado para instruir o nó de saída para enviar um segundo pacote a um nó de entrada do primeiro túnel, no qual o segundo pacote é usado para indicar que um erro de bit ocorreu no primeiro túnel. o presente método pode transferir informações de erro de bit e implantar comutação de ligação de serviço ponto-a-ponto.
