Дослідження впливу таймерів у протоколі GLBP на відмовостійкість мережі

Abstract

The paper investigated the impact of timers in the GLBP protocol on network fault tolerance. GLBP uses Hello and Hold timer to track the status of devices. The GNS3 package was used for the experiment. In order to investigate the network fault tolerance, the timer values were changed. When sending packets from one network to another, the failure of one of the routers was artificially organized in order to estimate how many packets will be lost before the network resumes its work. The experiment reduced the number of lost packets from 5% to 1% and accelerated the restoration of the network after the failure of one of the routers.
