[OpenWrt-Devel] [PATCH v3] ipvs: Linux IP Virtual Server kernel modules (netfilter.mk patch)

[Mauro Mozzarelli]

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 at the front of 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.
