Abstract

First this paper described the great challenge from the new era and its impacts on networks and indicated the huge capacity pressure faced by networks. Then, the paper discussed implications, effects and technical limits for the three basic laws which guide network era such as Moored Law, Optical Fiber Law and Metcalfe´s Law. Finally, the paper presented capacity evolution strategies for transmission links, transport nodes and service nodes in backbone networks, respectively.
