Shaporin R. Models and design techniques of enterprise computer networks communication systems

In a thesis the solution of the relevant scientific-practical problem, bound with automation of process of designing enterprise computer networks communication systems (ECNCS) is offered. The models, methods and tools of design, which provide construction ECNCS, optimal by criterion "productivity/cost", have small labour input and time of design are created. The object-oriented rules, which allow to select network non-blocking patterns of different levels of hierarchy ECNCS, minimum under the cost by formal means are offered. The mathematical model of a network transactions in а real communication channel is improved. The enterprise computer network object-oriented decomposition method is offered. The object-oriented information and mathematical models of switchs are designed. The object-oriented method of rising simulation ECNCS is offered. The method of an object-oriented design ECNCS, which provides obtaining optimal by criterion "productivity/cost" of the design solutions and allows to reduce timeof the design on 40% comparing with known structural methods of synthesizing ECNCS is developed.
