The era of information technology is currently developing rapidly, so people need a stable internet connection and able to support data and information exchange activities quickly. To support these needs, the network must be supported with backup links to minimize downtime and also so that high availability networks can be maintained. When there are many requests from network users, network devices will be burdened because they have to do a lot of service processes for requests from these users. this causes the connection to be slow and the connection to be lost if the network device cannot serve all the requests. The solution is to divide the traffic load that comes to network devices. The Load Balancing method can be used in dividing the traffic load that enters the network through several available network links so that it is not centered on one ISP (Internet Service Provider). The purpose of this study is to increase the throughput value so that traffic can run optimally. So that it can maintain network stability with the Load Balancing method and reduce the occurrence of downtime due to one ISP (Internet Service Provider) experiencing network problems by applying the Autofailover technology method. The results showed an increase in the throughput value after using the load balancing method, The measurement of the throughput value based on the TIPHON index has an average value of “4 (excellent)”. By maximizing the throughput value, it is expected to increase the upload speed and download speed of an ethernet link network. Furthermore, by applying the Autofailover method as a backup link when one connection is problematic or experiencing downtime, the backup link will automatically run to support all network traffic.
