The article is devoted to the development of a new approach of simulation models of network systems with IP-traffic. Emphasis is placed on methods for assessing the performance and quality of service in IP- based networks, and they distributed network systems. The principles of integrated architectures, IntServ and differential , DiffServ QoS in computer networks is done . A method for calculating the characteristics of the system with a guaranteed service architecture services IntServ is provided. An approach to the development of mathematical models of network systems with guaranteed service on the basis of (min, +) algebraic structures is proposed. Methods of «network calculus», the development of an algebraic approach to the description of service systems to estimate their performance are presented. The characteristics of the algebraic structure dioid is adequate representation of the model (min, +) filtering of network traffic is done. A simulation model of the network system (min, +) filtering is presented. Operators and programming construction on functional programming language for the implementation of the proposed simulation model are described. A software implementation of the network balance equation on functional programming language is implemented.
