摘要:

基于软交换技术的下一代网络(NGN)具有分组化的、开放的、分层的网络体系结构,是未来网络的发展方向。本文通过研究当前软交换网络QoS的解决方案,提出了基于业务感知技术的贵州大学下一代校园网动态QoS模型。通过在OPNET中建立下一代校园网的网络模型,并对相关业务的QoS性能进行仿真,结果表明业务感知技术能为下一代校园网中的QoS提供一定的保障。

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.
