Abstract: The present disclosure provides example data transmission methods and apparatuses. One example method includes obtaining a radio signal by using an input port. Based on a correspondence between an input port and a bearer channel, a bearer channel corresponding to the radio signal is determined. Code Division Multiple Access (CDMA) modulation and carrier modulation on the radio signal are performed according to a codeword and a frequency sub-band corresponding to the bearer channel, to obtain a modulated electrical signal. The modulated electrical signal is then modulated to an optical wavelength corresponding to the bearer channel to obtain a modulated optical signal, and the modulated optical signal is sent to an optical network.

Abstract: An embodiment of the present invention discloses a co-processing acceleration method, including: receiving a co-processing request message which is sent by a compute node in a computer system and carries address information of to-be-processed data; according to the co-processing request message, obtaining the to-be-processed data, and storing the to-be-processed data in a public buffer card; and allocating the to-be-processed data stored in the public buffer card to an idle co-processor card in the computer system for processing. An added public buffer card is used as a public data buffer channel between a hard disk and each co-processor card of a computer system, and to-be-processed data does not need to be transferred by a memory of the compute node, which avoids overheads of the data in transmission through the memory of the compute node, and thereby breaks through a bottleneck of memory delay and bandwidth, and increases a co-processing speed.
