Abstract:The communication network and the inter-net are made up of the transmission and switching. At present, the revolutionary transformation of the transmission has been completed from electricity to light , but the switching is still operated in electricity. According to the theory of the distributed network designing, this paper presents a structure of next generation network structure with great information flow based on the new distributed wavelength division multiplexing and fiber division multiplexing optical circuit switching technology. The security problem will be solved on the network structure itself.
