Abstract
Provided are techniques related generally to computer communication and, more specifically, to techniques that provide legacy applications with access to a cluster infrastructure. A pseudo interface layer provides applications with internet protocol (IP) family sockets access to cluster awareness protocols in a manner that may be transparent to both the application and the cluster awareness layer of a kernel.
