NGN test strategy: Evaluating Next Generation Networks in a realistic environment

Telecommunication networks are inevitably subject to a great migration from what they are now to what is a converged network in which various services with different or even contrast entities are delivered in an integrated way. Next generation network (NGN) is a manifest example of such networks. Examining and evaluating a new networking technology is a challenging work due to the sensibility of matter. In this paper a test strategy is proposed for testing NGN. This strategy has been applied in a nationwide NGN test environment and will be elaborated in this paper.
