STUDY OF RELIABILITY AND FAULT TOLERANCE MANAGEMENT IN INFORMATION AND COMMUNICATION NETWORKS: MODELING AND TESTING OF DEFAULT GATEWAY REDUNDANCY PROTOCOLS
The article is devoted to researching reliability and fault tolerance management mechanisms in infocommunication networks, focusing on modeling and testing of gateway redundancy protocols. The work considers the VRRP (Virtual Router Redundancy Protocol) and GLBP (Gateway Load Balancing Protocol) protocols, which ensure continuous network operation in the event of a primary gateway failure. The purpose of the study is to compare these protocols using the virtual environments EVE-NG and Containerlab, as well as to test them on physical and virtual devices.
