Research Of IP/DWDM Network

The exploding increase of Internet Protocol service and the rapid advance of Dense Wavelength Division Multiplexing have create qualification for the directly bearing IP service in the new DWDM network. Relying on its two penny network whole cost, upper network efficiency , providing more bandwidth and direct over All Optical Network high efficient structure, IP/DWDM grows up rapidly and becomes the furthest cost-efficient 3G optical internet framework. Many countries are researching the next generation broadband high-speed optical internetworking facing IP service. The reappear several IP/DWDM integrated schemes. For the sake of breaking through the bottle neck limit of mismatching between high speed optical signal in optical layer and low speed electronic switching in traditional core router, IP/DWDM optical network synthesizes the advantage of controlling capability of MPLS and large-capacity switching and transmitting of optical switching device. It is the developing direction of future optical network and the hotspot in optical communication field research. The research of IP /DWDM takes on important scientific signification.This text proceeded from development trend of the network, successively introduced two kinds of key technology schemes while IP/DWDM network merges: GMPLS technological scheme and OBS technological scheme, and the scheme combined to GMPLS with OBS on this basis carries on research, on the basis of summarizing others' research results, have proposed low QoS guarantee of losing the bag rate with high efficiency that one is named Smart QoS resources reserving the mechanism to realize by the author, and use this technology, this text has proposed a kind of Smart LOBS network scheme. According to this kind of thinking, this text has four chapter contents in all: Chapter one,...
