Abstract

Disclosed are a method, device and system for transmitting data in a coaxial network. The method comprises: in a current transmission cycle, obtaining the total length of data to be sent cached by a head end device; determining, according to sending duration of the total length of the data to be sent cached by the head end device, a downlink time slot length; when a next transmission cycle arrives, sending to a terminal device time slot indication information at least comprising the determined downlink time slot length; sending, according to the determined downlink time slot length, the data to be sent cached by the head end device to each terminal, and receiving terminal cached data sent by the terminal device. In the solution provided by the embodiments of the present invention, the head end device determines, according to the sending duration of the length of data thereof to be sent in the current transmission cycle, the downlink time slot length of the next transmission cycle, thereby dynamically adjusting, according to the size of the current downlink service stream, the downlink time slot length, so that the downlink time slot length matches the service traffic to the greatest degree, thus improving the bandwidth utilization ratio.
