ROUTING METHODS FOR ENSURE QUALITY OF NETWORK SERVICE

Abstract

Relevance. The relevance of routing methods to ensure the quality of network service remains high in today's digital world. A significant increase in the volume of data transmission in networks is due to the growth of the number of connected devices and the development of the Internet of Things. This requires more efficientmanagement of bandwidth and latency to ensure adequate quality of service. Today's networks are used for a wide range of applications, from web browsing and e-mail to video conferencing, online gaming, and highdefinition video streaming. Each application has its own unique requirements for quality of service, which leads to the need for various routing methods to ensure optimal performance. It should also be noted that the increasing popularity of streaming multimedia services, such as Netflix, YouTube, and Spotify, requires high bandwidth. and low latency to ensure a satisfactory level of service. Given these factors, routing methods to ensure the quality of network service remain a key element in the design and management of network infrastructure, and their development and optimization are an integral part of ensuring high performance and reliability of network services. The purpose is a study of existing routing methods to ensure the quality of network service. The object of the study is the evolution of FPGA accelerators for data center (DC) and cloud computing. The subject are methods of multithreaded routing of computer networks. Results. An analysis of the existing methods of multithreaded routing was carried out. The existing works on the analysis of the effectiveness of multithreaded routing are analyzed. Multipath TCP and Flow Distribution Management Protocol protocols were selected for comparative analysis as representatives of static and dynamic methods. The main research methodology is a combination of simulation modeling and statistical tests. The main hypothesis is that dynamic methods will outperform static methods in multithreaded routing. This hypothesis is tested on the basis of modeling the behavior of multithreaded routing methods from the considered SDN controller operation strategies. A description of the method of controlling controllers in software-configured networks for the implementation of built routes of a multi-flow connection is given.
