  Abstract

Load balancers, which distribute traffic to multiple servers, perform health checks on connected servers to prevent service disruptions caused by server failures. So far the health check methods have used health check packets that are transmitted at a certain interval to determine the status of the server. Depending on the user"s settings, various types of packets such as ARP, ICMP, TCP, Script, etc. are supported, and the load balancer supports uninterrupted service by identifying the status of the server and excluding equipment that has failed without user intervention in the event of a failure. However, the health check method currently provided by the road balancer has a problem of having a long disability detection time. Therefore, in this paper, a health check method is proposed that can detect the failure situation quickly using packet statistics received from the interface connected to the server.
