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.
Who Can Benefit
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.
