IIOP(Internet Inter-ORB Protocol) The CORBA message protocol used on a TCP/IP network (Internet, intranet, etc.). CORBA is the industry standard for distributed objects, which allows programs (objects) to be run remotely in a network. IIOP links TCP/IP to CORBA's General Inter-ORB protocol (GIOP), which specifies how CORBA's Object Request Brokers (ORBs) communicate with each other.
IIOP was built into Netscape's browser starting with Version 4.0. When a user accesses a Web page that uses a CORBA object, a small Java applet is downloaded into Netscape, which invokes the ORB to pass data to the object, execute the object and get the results back. See CORBA.
