Vectored-DSL method and system, board, and DSLAM device

The present invention discloses a method for transmitting data. In the embodiments of the present invention, whether to send blocking information used to block low priority data sent by an upper layer is determined through monitoring a delay of data during transmission, so as to prevent data overflow in a retransmission buffer of the sending end, thus achieving higher INP protection for the low priority data. Meanwhile, only the low priority data is blocked at this time, therefore, a sending end may further continue receiving high priority data, and mark the high priority data with a flag indicating retransmission is not needed when encapsulating the high priority data, so that a receiving end does not apply for retransmission of the high priority data when receiving the high priority data, thus ensuring the short delay requirement of the high priority data.

Method and apparatus for transmitting data, and communication system

The present invention provides a method, an apparatus, and a system for time synchronization of an xDigital Subscriber Line (xDSL). The method includes: transmitting, by a customer premises equipment (CPE), a first symbol to a central office (CO) equipment, and obtaining time Tsindicating the moment that the first symbol is transmitted; receiving, by the CPE, a second symbol transmitted by the CO, and obtaining time Tsindicating the moment that the second symbol is received; obtaining, by the CPE obtains time Tmindicating the moment that the first symbol is received by the CO and time Tmindicating the moment that the second symbol is transmitted by the CO; the CPE calculates an offset between a clock of the CPE and a clock of the CO according to Ts, Ts, Tm, Tmand a delay of the CPE; and the CPE adjusts the clock of the CPE according to the offset to achieve synchronization. According to the present invention, by adjusting the time of the clock of the CPE and the time of the clock of the CO, the offset between the clock of the CPE and the clock of the CO can be obtained accurately to effectively achieve time synchronization between the CPE and the CO.
