+What is Keepalived ?
+
+The main goal of the keepalived project is to add a strong & robust
+keepalive facility to the Linux Virtual Server project. 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.
