Modeling arrival rate and service rate for next generation network as an open queue using M/M/1 queue model

The challenges of new communication architecture are to offer better quality of service (QoS) in the Interne. A large diversity of services based on packet switching in 3G network and beyond 3G leads dramatic changes in the characteristics of the data traffic. As many real time services and multimedia application becomes popular, providing guaranteed quality of service to Internet user is an important issue for next generation of traffic management. Efficient content delivery of multimedia services is one of the major concerns for next generation network. Deployment of application server and resource database 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 that the network can be viewed as a queue or a waiting line. 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 are shared. In this paper, NGN reference architecture have been considered as the M/M/1 queue model which has been analyzed with exponential interarrival times with mean 1/λ, exponential service times with mean 1/μ and a single server or facility being represented by the NGN itself. Customers which for example can be a request for a web page, a message received for transmission from other networks or media broadcast. Customers are served in the order of arrival.
