Applications with time restrictions are becoming common in our daily lives. These applications range from games to applications for controlling air traffic. Applications with time restrictions that use the Internet / Intranet as a mean of communication (e.g. streaming audio and video, VoIP and messaging PRC-RT), require that their packets be delivered before the end of its deadline. In these cases prioritize traffic from the packets generated by these applications in relation to the other packets is a way of trying to minimize the loss of deadlines. Thus this work presents an architecture of gateway with QoS and traffic forecasting that aims to focus on requests from time-restricted applications. Gateway classifies traffic based on the IEEE 802.1q standard, in six classes with different priorities and uses the Box-Jenkins mathematical model to predict the amount of traffic for each class of service and provide resources to meet the classes according to their priority.
