Analysis of a Model for Improving the Efficiency of Routing Control in Data Transmission Networks Based on Fuzzy Logic
Abstract
The article considers the principles and mechanisms of packet switching in data transmission networks based on virtual and datagram modes. The structure of the packet switching node and the description of the functioning of the block for receiving frames from the network path, the block for transmitting frames to the network path, the block for interaction with local subscribers and the routing block are given. The functional diagram of the router and the description of interface levels, network protocol and routing protocols are considered. The analysis of the traditional method of routing in a data transmission network with packet switching is carried out and the necessity of using intelligent adaptive technologies is substantiated. The possibility of applying the mathematical foundations of fuzzy logic in the process of routing packets in a data transmission network with packet switching is considered, the concepts of fuzzy and linguistic variables are given. An approach and a mechanism for estimating the route metric based on fuzzy logic are presented, its main input and output parameters are determined and analyzed. A model of a routing control system using a fuzzy logic apparatus has been developed to improve the efficiency of routing control in data transmission networks.
