Description of the illustration netag107.eps
This illustration shows a client/server application connection using Oracle Net. The client shows a communication stack. From the top down, the stack is constructed with the following layers:
- 
                  Application 
- 
                  Oracle Net 
The database server also shows a communication stack. From the top down, the stack is constructed with the following layers.
- 
                  RDBMS 
- 
                  Oracle Net 
The TCP/IP network protocol resides between the client and the database server.
During the connection, the client application communicates with the Oracle Net layer. In turn, Oracle Net communicates with the TCP/IP protocol, which passes the connection to the Oracle Net layer on the database server.
