Abstract

Disclosed is a method to bind UNIX domain sockets and FIFOs to a cluster wide namespace involving a managing cluster facility. The Problem Many business applications use Unix Domain Sockets and Named Pipes (FIFOs) for Inter-Process-Communication. They usually cannot run in a distributed manner through a network because the sockets of these communication methods are bound to the local system. Two obstacles are currently precluding running the threads of such an application in a distributed manner in a cluster environment: the namespace of these sockets is bound to the local node and the data to be transmitted is bound to the node holding the instance of the socket. IP sockets, as an alternate approach for Inter-Process-Communications, solve these problems but, due to their extensive dislocality, using them goes along with significant overhead in processing and disadvantages related to security. The Solution
