Training Course Summary:

The Network Programming course provides students with the information needed to apply network programming concepts and techniques, including the Open Systems Interconnection (OSI) seven-layer model. The course can also teach how to write network programs for both stream and datagram communications with both sockets and Transport Level Interface (TLI), how to use the client-server model in network programs, how to write RPC network programs, and how to implement network security. The course covers network programming facilities on the Solaris Operating Environment, including transmission control protocol/internetwork protocol (TCP/IP), UDP/IP, sockets, TLI, remote procedure call (RPC), UNIX, and Data Encryption Standard (DES) network security facilities.

Pre-Requisites:

To succeed fully in this course, students should be able to:

Understand basic Solaris UNIX commands
Use the Solaris symbolic debuggers: dbx or debugger

Who Should Attend:

Students who can benefit from this course are experienced C programmers who are proficient in system interface programming and want to be involved in network programming.
