A set of rules that defines how data is transported across networks. Protocols supported by Oracle Net Configuration Assistant include:
IPC
The Interprocess communication (IPC) protocol is used for client applications that are on the same computer as the listener. IPC can provide a faster local connection than TCP/IP.
Named Pipes
Named Pipes is used on PCs that are not using TCP/IP. Named Pipes is available only on Windows NT.
TCP/IP
The Transmission Control Protocol/Internet Protocol (TCP/IP) is the de facto standard Ethernet protocol used for client/database server conversation over a network. TCP/IP enables an Oracle application on a client to communicate with remote Oracle databases through TCP/IP (if the Oracle database is running on a host system that supports network communication using TCP/IP).
TCP/IP is the standard networking protocol. It is used overwhelmingly by both UNIX and PC based networks. It is also the protocol with which Internet connections are made.
TCP/IP with SSL
The TCP/IP with Secure Sockets Layer (SSL) protocol enables an Oracle application on a client to communicate with remote Oracle databases through TCP/IP and SSL (if the Oracle database is running on a host system that supports network communication using TCP/IP and SSL). TCP/IP with SSL is only for use with the SSL authentication method.
