The efficiency of the DPI system for identifying traffic and providing the quality of OTT services

摘要

In this article, the authors introduce a definition of the term OTT service, describe the attendance of these services and compare them with traditional attendance. Also here is shown the classification of services provided by OTT-services. In this article, the authors identify the problems related with the data transfer through the telecom operator networks. Authors show different classes of traffic priority, based on the requirements and behavior of certain types of applications, allowing maximum flexibility in the transmission of user information. Due to this for the necessary correction of the network's work, the authors give perspective approaches and DPI-technology procedures which provide the necessary requirements for QualityofService when they make provision of services of its network for OTT-services. The authors review the possibilities of using the DPI-system on the network and its interaction with OTT-services based on open solutions. In this paper, we obtained graphs of the results of the experiment and reviewed the efficiency of signatures, derived formulas for estimating the probability of events, and applied them to the suitable statistical analysis.
