  • receivers are responsible for requesting resource reservation
  • hosts and routers run RSVP software (daemons) to be capable of participating in resource reservation
  • RSVP protocol is used to pass the QoS request to all nodes (routers and hosts) along the reverse data path to the data source
  • at each node, the RSVP program applies a local decision procedure (called admission control) to determine whether it can supply the requested QoS
  • if admission control succeeds, the RSVP program sets the parameters to the packet classifier and scheduler to obtain the desired QoS
