The advent of the Internet/intranet has led to the formalization and categorization of the various types of intercommunications among the different architectural entities.

The Internet/intranet—from the perspective of the CIF—is the line of communication along which data flows and the different components interact with each other. Figure 11.1 shows that the Internet/intranet handles those communications that occur within the confines of the CIF.

The purpose of this communications fabric is to:
