Ngn Commercial Trial Network Design And Performance Testing

The thesis through the research to NGN trial network,it studies NGN and its the essential technical principle,it analyzes the mechanism of the NGN network design,it explores each kind of question which NGN commercial center possibly appears,and it seeks suits the existing network condition the plan,the paper research content belongs to one of current correspondence domain research hot spots,has the widespread practical application prospect.The paper unified the existing telecommunication network evolution,the theoretical analysis and the system constructs actually unifies,elaborated NGN and its the essential technical principle,through the NGN experiment network exploration telecommunication network evolution,confirms the Softswitch network way the feasibility,the research multilayer system overhead construction nimble network,the enhancement network security,how discusses realizes IP the load bearing network QoS service quality guarantee and the network and the user safety mechanism,discusses when the large-scale network the network and the equipment exchange,the network management realization,the IP allocation question.Carry on the evolution strategy by the NGN network organizational structure and the technology to the existing network the research as well as the plan,seeks the experience in the actual design and in the application for the next step of NGN development tendency.In the Softswitch platform of the trial nework to develop the new service,at the same time the service platform which presently hangs the PSTN net on migrates to the Softswitch platform in,unifies to the service platform movement maintenance management,at the same time may combine the existing service in the unified service platform,has the new service type.The paper returned to give back to the service test and the application example,by proved these technical and the measure validity,the feasibility and the usability.
