Traffic Analysis in the Intelligent Network
The fundamental aspect of the intelligent network (IN) is the ability to support the creation of services for the end customer in a rapid manner. Traditional telephone services are not growing much, and to survive in the marketplace, many services providers are looking for new services that will meet the customers’ needs and bring in revenue. The advanced IN network provides the multimedia communications include the videophone, video teleconferencing and remote access to multimedia databases. The IN network basic call model is done. This model describes the operations that the service switching point (SSP) and service control point (SCP) executes. The two type data packets of each call arrive according to a Poisson process with rates λ1, λ2 and are served by two separate channels with exponentially distributed transmission time. Using the Markov chains exact analytical queueing model was created for IN network call service process. The Markov chains state transition diagram is taken. A careful IN network performance analysis effort is taken by accurate analytical model. IN network queueing performance measures such as mean queue lengths, the mean waiting times, call loss probabilities in finite buffers system is taken. An exact system analytic model is very complicated when the buffer sizes in SSP and SCP are large, because Markov chains has a large number of states and more general study of system may be achieved via simulation.
