Chapter 10 Network Communication This chapter describes how: • TIBCO iProcess Workspace communicates with the iProcess Engine. See TIBCO iProcess Workspace and TIBCO iProcess Engine Network Communication. • TIBCO iProcess Engines communicate when they are in a node cluster. See TIBCO iProcess Engine to TIBCO iProcess Engine Network Communication in a Node Cluster. • The iProcess Engine works when a firewall is implemented on your network. See Using the TIBCO iProcess Engine in a Firewalled Environment.
