The Red Hat LVS cluster is based either directly on contributions from the Linux community, or on components that were inspired or enriched by various Linux community projects.
The primary source of the LVS cluster is Wensong Zhang's Linux Virtual Server (LVS) kernel routing algorithm (see http://www.linuxvirtualserver.org). The capabilities of the LVS project that the Red Hat LVS cluster currently supports are:
Building virtual servers: floating IP addresses where requests for service arrive from the public internet.
Routing service requests from virtual servers to a pool of real servers.
Load-balancing (see Table 8-1).
Packet-forwarding (see the section called Routing Methods).
Persistent connections.
The LVS innovations supported by the Red Hat LVS cluster are based on a number of technologies. For a good general discussion and index of the relevant HOWTOs on these and related topics, see http://www.linas.org/linux/load.html.
