Oracle Internet Directory and the Oracle Technology Stack

Figure 26-1 gives an overview of the various components of the Oracle Internet Directory stack. Stack communication between separate computers occurs by passing information from one node to the other through several layers of code. Information descends through layers on the client side. It is then packaged for transport across a network medium. The information then proceeds up the stack on the server side where it is translated and understood by the corresponding layers.
