Basic Architecture

The basic architecture of the system is as shown in the illustration below, all components run the rsvpd daemon, however only the router is responsible for making requests to the Operating System (OS) for resources. The presence of RSVP daemons on the hosts are to enable the communication with the RSVP on the router. The hosts can also use an application program RTAP supplied with the public domain implementation of RSVP from ISI.
