Abstract
The present invention is directed to a method, system, and computer program product for providing local load balancing for high-availability servers. In particular, the present invention is based on the use of an HACMP cluster of servers (for high availability) each running an instance of a TCP splitter (for load balancing). A cluster of servers is provided, wherein a Transport Control Protocol (TCP) splitter runs on each of the servers. Each TCP splitter is configured to split an incoming data stream to a respective server among a plurality of the servers for processing. Each server in the cluster has a different routable Internet Protocol (IP) address. Upon a failure of a server, the IP address of the failed server is reassigned to another server in the cluster.
