The achievements of modern science and technology make the human organs in space has been greatly extended, if the telephone is the extension of human voice, television is the extension of human vision, the data center is the extension of the human brain, then the network is a variety of extensions, as well as between the extension and the subject exchange information between the transmission of the instructions of the nervous system. The normal nervous system is one of the basic signs of a healthy human being, similarly, the large bandwidth, the low time delay, the high reliable network system is also makes the human various organs to extend effectively, enters the cloud age the basic guarantee. Cloud business's challenge to the network as information services enter ...
