Research of fast and safe large files transmission based on Socket

In the large files transmission based on Socket, in order to improve the transmission speed and enhance the content safety, this paper puts forward the thinking of fast and safe large files transmission based on Socket, it makes use of the Socket asynchronous communication and multi thread, file compression and decompression, self-adaptive file segmentation and resume broken transfer, and realizes the fast and safe files transmission. The experiment shows that, the thinking of fast and safe large files transmission receives the well effect and has upper pragmatic value.
