Structural Synthesis of an Interface Center for Corporate Networks
Abstract
Purpose: The functions of combining and harmonizing heterogeneous networks in the structure of a corporate network are performed in interface centers of various levels: bridges, switches, routers and gateways. These interface centers are based on processors with typical architectures: I386, PowerPC, ARM, RISC, etc. The architecture is rigidly anchored to the functionality, making it difficult to flexibly manage the resources and distribute the load. On fixed tasks, the performance of an interface center is used only by 10-20%. An alternative is a dynamic adjustment of the interface center structure, depending on the task and on the ambient conditions. The purpose of this work is developing methods for building interface centers for heterogeneous information networks with a given set of properties. Results: А model is proposed for an interface center of corporate information networks, with a minimally complete set of structural elements common for all kinds of interface centers. This model is versatile for many problems of interface center structure synthesis. A structural synthesis technique is developed, different from the existing ones, as it jointly uses the stages of automatic generation of many alternative structures for an interface center using a genetic algorithm and "manual" selection of the preferred option for multicriteria synthesis of the interface center structure under conditions close to real ones. Practical relevance: The technique of interface center structure synthesis may find application in solving the problems of developing corporate information systems and choosing network equipment.Published
