11.7.2. About IOR

An Interoperable Object Reference (IOR) is used in a CORBA system to identify objects. It consists of several pieces:
  • Object type.
  • Host name of the server.
  • Port number of the server.
  • An object key, which identifies the object.
The host name and port number are used to communicate with the server and the object key is used by the server to identify the object.
