CORBA Transport Protocol: IIOP
The IIOP specification defines a set of data formatting rules, called CDR (Common Data Representation), which is tailored to the data types supported in the CORBA Interface Definition Language (IDL)
Using the CDR data formatting rules, the IIOP specification also defines a set of message types that support all of the ORB semantics defined in the CORBA core specification
The messaging formats and the CDR constitute the General Inter-ORB Protocol (GIOP).
IIOP is the GIOP message format sent over the Transmission Control Protocol/ Internet Protocol (TCP/IP).
- Using IIOP any CORBA client can speak to any other CORBA Object.The architecture states that CORBA objects are location transparent.
