At present, along with popularizing of 802.11.ac agreement, transmission speed between distinct device will there will be very large difference, when the sending ending equipment of a such as 11.ac (1Gbps) gives the receiving device transmitting file of a 11.g (54Mbps), owing to being limited to the transmission speed of receiving device, the transmission speed of sending ending equipment is 54Mbps at the soonest, for the sending ending equipment of 11.ac, its bandwidth availability ratio only has 5.4%, and need transmission time of growing very much, do not reach expection far away.
In order to solve the problems of the technologies described above, disclosure embodiment provides a kind of data transmission method, and the method can be used in data distributing program, system or device, as shown in Figure 1, and the method comprising the steps of S101-S103:
In step S101, determine whether the first local network interface card speed is greater than the second network interface card speed of data receiver, when determining whether the first local network interface card speed is greater than the second network interface card speed of data receiver, the local second network interface card speed that independently can detect the first network interface card speed and data receiver, then independently determine whether the first network interface card speed is greater than the second network interface card speed of data receiver according to testing result, whether the first network interface card speed that can certainly receive this locality that data forwarding device sends is greater than the judged result of the second network interface card speed of data receiver, then determine whether the first local network interface card speed is greater than the second network interface card speed of data receiver according to this judged result.

When the first network interface card speed is greater than the second network interface card speed, illustrate that data receiver is high-speed network appliance, data receiver is slow network equipment, the maximum data transfer rate of data receiver is greater than the maximum data transfer rate of data receiver, therefore, when outgoing data is sent to data receiver by data receiver, if outgoing data is directly all sent to data receiver by means of only single wire transmission passage, the message transmission rate of data receiver can because be limited to the second network interface card speed of data receiver, and reduce the utilance in local broadband and increase the data transmission period of data receiver, therefore, while send the first data in outgoing data to data receiver, if local network bandwidth has residue, the second data in outgoing data then can be sent to data forwarding device, to be completed the transmission of outgoing data by Double wire transmission passage, thus improve the utilance of local bandwidth, shorten the data transmission period of data receiver and extend service time of battery and the useful life of data receiver.
In step s 103, do not send to second data retransmission of data receiver to data receiver data receiver by data forwarding device.
To directly not send to second data retransmission of data receiver to data receiver by data forwarding device, the complete outgoing data that data receiver can receive data receiver and sends can be guaranteed, certainly, if the message transmission rate of data forwarding device support is greater than the first network interface card speed, now the first data also can be empty, namely outgoing data is all transmitted to data forwarding device by data receiver, still outgoing data is sent to data receiver indirectly by single channel, in this case, message transmission rate due to data forwarding device support is greater than the first network interface card speed, therefore, still the data transmission period of data receiver can be shortened, improve the bandwidth availability ratio of data receiver.
As shown in Figure 2, in one embodiment, above-mentioned steps S102 can be performed as:
