Forward transmission network data processing device and method

The invention provides a forward transmission network data processing device and method, the device comprises a processor, at least one high-speed forward transmission interface and at least one low-speed forward transmission interface. The processor comprises a protocol frame processing module used for converging data uploaded by a plurality of low-speed forward transmission interfaces into a group of data as first target data; selecting one of the high-speed forward interfaces as a first target interface, and sending the first target data to forward network transmission equipment through thefirst target interface; and selecting one of the high-speed forward interfaces as a second target interface, receiving the data issued by the forward network transmission equipment through the secondtarget interface as second target data, and finally distributing the second target data to the corresponding low-speed forward interface. According to the method and the device, the interconnection problem of low-speed forwar
