CGI: Common Gateway Interface. Note: This page is no longer maintained. It is left here for historical purposes. Unfortunately, over time, some links may break that are not maintained by the entities managing those resources. An HTTP server is often used as a gateway to a legacy information system; for example, an existing body of documents or an existing database application. The Common Gateway Interface is an agreement between HTTP server implementors about how to integrate such gateway scripts and programs. It is typically used in conjunction with HTML forms to build database applications.
On the interconnect side, the SBC maps to the IBCF, IWF at the signaling plane and TrGW (Transition Gateway) at the media plane. From an IMS/ TISPAN architecture perspective, the SBC is the integration of the P-CSCF and C-BGF functions on the access side, and the IBCF, IWF, THIG, and I-BGF functions on the peering side.
