This chapter describes how to configure Resource Reservation Protocol (RSVP), which is an IP service that allows end systems or hosts on either side of a router network to establish a reserved-bandwidth path between them to predetermine and ensure QoS for their data transmission.

RSVP allows end systems to request QoS guarantees from the network. The need for network resource reservations differs for data traffic versus for real-time traffic, as follows:
Data traffic seldom needs reserved bandwidth because internetworks provide datagram services for data traffic. This asynchronous packet switching may not need guarantees of service ...
