Network line codes have been used, called signaling system 7 (ss7) that is associated with the earliest U.S. selection, due to the underlying investment is huge, and the evolution of the long-term evolution, also proved the selection is correct, so the bottom layer of network development and investment has been the telecoms giant and the international telecommunication union rot, also accord with the interests of all parties,
It is difficult to change in the pattern under the premise of the development of network mainly concentrated in the function layer and application layer,
In most cases, the general developers really is not necessary to understand the various complex underlying protocol, as long as do the network connection and link the code, will do the trick,

Network links, generally refers to the network connection is stable and reliable, to establish a network link, usually need to follow with the network provider and to access the site between some of the agreement, is not that they do they do it,
