The main goal of the keepalived project is to add a strong & robust keepalive facility to the Linux Virtual Server project<\/a>. This project is written in C with multilayer TCP\/IP stack checks. Keepalived implements a framework based on three family checks : Layer3, Layer4 & Layer5\/7. This framework gives the daemon the ability of checking a LVS server pool states. When one of the server of the LVS server pool is down, keepalived informs the linux kernel via a setsockopt call to remove this server entrie from the LVS topology. In addition keepalived implements an independent VRRPv2 stack to handle director failover. So in short keepalived is a userspace daemon for LVS cluster nodes healthchecks and LVS directors failover.<\/p>\n
