In distributed computing, General Inter-ORB Protocol (GIOP) is the message protocol by which object request brokers (ORBs) communicate in CORBA. Standards associated with the protocol are maintained by the Object Management Group (OMG). The current version of GIOP is 2.0.2. The GIOP architecture provides several concrete protocols, including:

1. Internet InterORB Protocol^[1] (IIOP) — The Internet Inter-Orb Protocol is an implementation of the GIOP for use over the Internet, and provides a mapping between GIOP messages and the TCP/IP layer.^[2]
2. SSL InterORB Protocol (SSLIOP) — SSLIOP is IIOP over SSL, providing encryption and authentication.
3. HyperText InterORB Protocol (HTIOP) — HTIOP is IIOP over HTTP, providing transparent proxy bypassing.
4. Zipped InterORB Protocol (ZIOP) — A zipped version of GIOP that reduces the bandwidth usage
