+  IPVS (IP Virtual Server) implements transport-layer load balancing
+  inside the Linux kernel, so called Layer-4 switching. The command line tool
+  ipvsadm is used to set up, maintain or inspect the virtual server table
+  in the Linux kernel. The Linux Virtual Server can be used to build scalable
+  network services based on a cluster of two or more nodes.
