RSVP: Resource Reservation Protocol
Resource Reservation Protocol (RSVP) is a resource reservation setup protocol designed for quality integrated services over the Internet. RSVP is used by a host to request specific qualities of service from the network for particular application data streams or flows. RSVP is also used by routers to deliver quality-of-service (QoS) requests to all nodes along the path(s) of the flows and to establish and maintain state to provide the requested service. RSVP requests will generally result in resources being reserved in each node along the data path.
