Abstract

um método e um sistema de transmissão de arquivo. o método inclui as etapas de: estabelecer pelo menos duas conexões para uma extremidade de recepção, cada conexão incluindo pelo menos uma janela de envio (s101); dividir um arquivo a ser enviado em pelo menos dois blocos de dados, preenchendo um bloco de dados correspondente em uma janela de envio de cada conexão, e enviar o bloco de dados à extremidade de recepção usando a janela de envio (s102); adquirir informações de confirmação retornadas, após a extremidade de recepção receber o bloco de dados, pela extremidade de recepção, as informações de confirmação incluindo informações de bloco de dados recebido no momento e informações de bloco de dados que a extremidade de recepção espera receber (s103); e limpar, de acordo com as informações de confirmação, uma janela de envio correspondente à informação de bloco de dados que é recebida no momento usando a conexão, preencher, na janela de envio limpa, um bloco de dados que a extremidade de recepção espera receber, e enviar o bloco de dados à extremidade de recepção, utilizando a janela de envio (s104). a utilização de largura de banda é melhorada e um tempo de transmissão de arquivo é reduzido por meio de simultaneidade de multijanela e multiconexão e distribuição bloco de dados adequada.a method and a file transmission system. The method includes the steps of: Establishing at least two connections to a receive end, each connection including at least one send window (s101); dividing a file to be sent into at least two data blocks by filling a corresponding data block in a send window of each connection, and send the data block to the receiving end using the send window (s102); acquire acknowledgment information returned after the receiving end receives the data block, by the receiving end the acknowledgment information including currently received data block information and data block information that the receiving end expects to receive (s103) ); and clearing, according to the confirmation information, a send window corresponding to the data block information that is currently received using the connection, fill in the clean send window a data block that the receiving end expects to receive , and send the data block to the receiving end using the send window (s104). Bandwidth utilization is improved and file transmission time is reduced through multi-window and multi-connection concurrency and proper block data distribution.
