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. |
