Abstract:

The Next Generation Network (NGN) based on softswitch is the trend of the network in the future due to its characteristics of packetizational, open and hierarchical network architecture. The dynamic QoS model of NGN based on traffic identifications in Guizhou University is proposed in this paper. The network model of the next generation campus network of Guizhou University is  established and the QoS performances of the relevant services are simulated in OPNET as well. It is proved that better QoS performance is achieved by the methods of traffic identifications.
