Annotation:  The investigation results of using guaranteed quality of service models with real time traffic in the secure corporate multiservice communication networks are presented in this paper. First of all the authors measured the peak and the mean data transmit speed, packet lengths and time between packets after terminal equipment using in secure corporate multiservice communication networks. These data were included in mathematical apparatus of deterministic network calculus theory for the real-time data streams modelling. The application results are witnessed about the inability to provide a specified delay-processing package in a border router, using guaranteed quality of service models, when grouping voice over IP data streams. More than that, in this paper the authors proved that application these models to description the speed parameters of video telephone data streams group, the real QoS complies with desired service, but only thanks to bandwidth over reserve. This paper consists of the introduction where the authors paid much attention to the relevance of the study, the theoretical analysis of existing mathematical network calculus models that supplies the readers by common definitions and terms of its applying, the experimental study of the adequacy of existing math models, the investigation results and conclusion

Keywords:  secure corporate multiservice communication networks, quality of service, criptotunnel, deterministic network calculus theory, bandwidth
