IPVS
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.
The IP Virtual Server Netfilter module for kernel 2.6
Status: The ipvs 1.2.1 is the latest stable version, it is
in the official kernel 2.6.10 released on December 24, 2004.
IPv6 support for IPVS was included in the Linux kernel 2.6.28-rc3 on November 2, 2008. See the wiki page of IPv6 load balancing for the status of IPv6 support.
Go to http://kernel.org/ to get a
clean copy of kernel 2.6.10 or later, and download the ipvsadm utility
at https://www.kernel.org/pub/linux/utils/kernel/ipvsadm/ to administer the IP Virtual Server inside the Linux
kernel. See the article Compiling ipvsadm on different Linux distributions at wiki.
Your testings, comments and bug report/fixes are very welcome. The

Status: The ipvs 1.1.x is development version for kernel 2.5.
Your testings, comments and bug report/fixes are very welcome. The
ChangeLog is available here.
If you like a single kernel patch, you don't need to download the
tar ball, just download a kernel patch and a separate ipvsadm srpm
here.

Source code via Subversion
What's Subversion? Subversion is a system for revision control, and
is designed to be a modern replacement of CVS. Start at
subversion.tigris.org to
learn more and read the Subversion Book.
The ipvs kernel code was already included in kernel 2.4 and
2.6. The source code of ipvsadm is available via Subversion. Anyone
can check out the sources via Subversion, but only certain people have
the ability to check in.
To browse around or download a few individual files, click
http://svn.linuxvirtualserver.org/repos/ipvsadm/.
To check out the sources, you need to be running Subversion client. For example, you can enter the following commands for checking out the latest source code of ipvsadm:
svn co http://svn.linuxvirtualserver.org/repos/ipvsadm/trunk/ ipvsadm
To check out ipvsadm source code for kernel 2.4, need to use the branch "ipvs-1-0-stable" in the Subversion checkout command.svn co http://svn.linuxvirtualserver.org/repos/ipvsadm/branches/ipvs-1-0-stable/ ipvsadm
Once you've checked out a copy of the source tree, you can update
your source tree at any time so it is in sync with the latest one by
running the command:
svn update
If you make some changes of the source code, please generate the
diff file and submit it to the mailing
list or me for inclusion.svn diff
