IPVS (IP Virtual Server) implements transport-layer load balancing, usually called Layer 4 LAN switching, as part of the Linux kernel. It's configured via the user-space utility tool.
IPVS is incorporated into the Linux Virtual Server (LVS), where it runs on a host and acts as a load balancer in front of a cluster of real servers. IPVS can direct requests for TCP- and UDP-based services to the real servers, and make services of the real servers appear as virtual services on a single IP address. IPVS is built on top of Netfilter.{{cite web | url = http://www.linuxvirtualserver.org/software/ipvs.html | title = IPVS Software - Advanced Layer-4 Switching | date = 2011-02-08 | accessdate = 2013-11-24 | publisher = linuxvirtualserver.org
IPVS is merged into versions 2.4.x and newer of the Linux kernel mainline.
