In this paper, we enhance our previous work regarding optimal resource allocation of next generation network services under a flat pricing scheme and quality of service policies. We present a complete framework that makes our model to dynamically allocate the resources whenever required. In order to do that, we apply an online traffic estimator and we monitor traffic changes using an Exponentially Weighted Moving Average control chart. Hence, the profit maximization of the provider is done efficiently. Finally, the performance of our framework is investigated through various simulation scenarios.
