IPVS (IP Virtual Server) implements transport-layer load balancing inside the Linux kernel, so called Layer-4 switching. IPVS running on a host acts as a load balancer before a cluster of real servers, it can direct requests for TCP/UDP based services to the real servers, and makes services of the real servers to appear as a virtual service on a single IP address.

IPVS On FreeBSD
The LVS On FreeBSD project was started by Li Wang, the goal is to port IPVS code to FreeBSD. Now, the LVS On FreeBSD module supports the LVS/DR and LVS/TUN ip load balancing technologies.
