Foil 9 RSVP Operational Principles (Continued)

From Reservation Protocol Large Web Application Class, CPS600/640 Fall 1997 -- Fall Semester 97. by Marek Podgorny * See also color IMAGE
At each node, RSVP applies a local decision procedure (admission control) to the QoS request.
  • If admission control succeeds, it sets the parameters to the Classifier and Packet Scheduler to obtain the desired QoS. If admission control fails at any node, RSVP returns an error indication to the application.
Each router in the path capable of resource reservation will pass incoming data packets to a Packet Classifier and then queue them in a Packet Scheduler.
  • The Packet Classifier determines the route and the QoS class for each packet. The Scheduler allocates a particular outgoing link for packet transmission.
