Data Processing Method, Communications Board and Device

摘要

Embodiments of the present invention provide a data processing method, a communications board and a device. 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.

主权项

1. A data processing method, applied in a data switching device comprising a first communications board, a second communications board and a time division multiplexing (TDM) service switching module, comprising:
acquiring, by the 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 slices of ODU data; encapsulating, by the first communications board, each slice of the ODU data into an Ethernet frame, wherein the Ethernet frame carries a destination Media Access Control (MAC) address and a payload area, wherein the destination MAC address directs to the second communications board and the payload area is used to store a slice of the ODU data and a serial number of the slice of the ODU data; and sending, by the first communications board, each Ethernet frame to the TDM service switching module.
