Keepalived for Linux

Keepalived for LVS aims to add a strong and robust keepalive facility to the Linux Virtual Server project. This project is written in C with multilayer TCP/IP stack checks. It implements a framework based on three family checks: Layer3, Layer4, and Layer5. This framework gives the daemon the ability of checking a LVS server pool states.When one of the servers in the LVS server pool is down, keepalived informs the Linux kernel via a setsockopt call to remove this server entry from the LVS topology. In addition, it implements a VRRPv2 stack to handle director failover.
