Abstract
In this paper we propose a method of evaluating the performance of a Softswitch that provides call control to voice services in NGN (next generation network). First, we describe the architecture for voice services in NGN and anatomize the call control processes such as call initiation, call re-initiation and call release of a voice connection. kiter that we propose a method of estimating appropriate server capacity of the Softswitch using approximate queuing model. Via numerical experiments we illustrate the implication of the work
