This is not a typo. OSI stands for "Open Systems Interconnectioni"
which is broad suite of protocols for data transmission in computer
networks following a seven layer model. The other suite of protocols
normally used on NSFNET/Internet is called the Internet suite or
commonly as the TCP/IP suite.

ISO stands for "International Standards Organization" and is the
standards body under which the OSI suite of protocols is being
developed. However ISO is not limited to computer networking
standards.  The standards for the paper sizes used on your copier or
the nuts and bolts sizes on your furniture were probably developed
under ISO.

ISO CLNP referred above is one of the Layer 3 (Network Layer)
protocols in the OSI protocol suite. This set of standard
protocols(OSI) is available in products from most major computer
vendors including the ones made by my employer Sun Microsystems Inc.
