National Information Network Wikipedia Other networking technologies such as ITU-T G.hn also provide a way to create a wired LAN using existing wiring, such as coaxial cables, telephone lines, and power lines. Synchronous optical networking and Synchronous Digital Hierarchy are standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using lasers. They were originally designed to transport circuit mode communications from a variety of different sources, primarily to support circuit-switched digital telephony. However, due to its protocol neutrality and transport-oriented features, SONET/SDH also was the obvious choice for transporting Asynchronous Transfer Mode frames. The independent, government-mandated organisation publishing performance and It is the successor of the Advanced Research Projects Agency Network developed by DARPA of the United States Department of Defense. The Internet utilizes copper communications and the optical networki...
