| 摘要 |
Embodiments of the present invention provide a data processing method, a communications board and a device, which relate to the field of communications technologies and can reduce a transmission delay of a TDM service. The method includes: acquiring, by a first communications board, an optical channel data unit ODU data flow; performing, by the first communications board, slicing processing on the ODU data flow according to a fixed frame frequency, so as to obtain various slices, where each slice includes a section of continuous ODU data in the ODU data flow; separately encapsulating, by the first communications board, each slice into an Ethernet frame; and sending, by the first communications board, each Ethernet frame to a time division multiplexing TDM service switching module in an Ethernet switching chip, so that the TDM service switching module sends each Ethernet frame to a second communications board to which a destination MAC address carried in the Ethernet frame directs. |
