RSVP refers to Resource Reservation Protocol. As the name suggests, it is used to reserve resources across a network, so when we look into the working of the RSVP. In the RSVP, the host’s request is carried throughout the network and then visits each node. It has two local modules for reservation of resources: the admission control module and the policy module. The admission module checks whether there are sufficient available resources, whereas the policy module checks the permission to make a reservation. After these two checks are performed, the RSVP uses the packet classifier and the packet scheduler for desired QoS requests.
