Interaction of Call Setup and Resource Reservation Protocols in Internet Telephony

In the Internet, call signaling, security association and resource reservation are handled by separate protocols and likely traverse different paths. However, for reliable service, the three functions may need to be coupled during call setup. We describe and compare several approaches to coupling, based on either single-phase setup or two-phase setup mechanisms. Our discussion is based on the Session Initiation Protocol (SIP), but also applies to other signaling protocols with similar properties.
