The challenges of new communication architecture are to offer better Quality of Service (QoS) in internet network. A large diversity of services based on packet switching in 3G network and beyond 3G leads dramatic changes in the characteristics and parameter of data traffic. Deployment of application server and resource server has been proposed to support both high data rates and Quality of Service (QoS) for Next Generation Network (NGN).One important generalization of the Next Generation Network is, it's a queue of network. It is expected that traffic in NGN will undergo both quantitative and qualitative changes. Such networks can model problems of contention that arise when a set of resources is shared.
