What Is a Service Business Model?

The main feature of the integrated service model is resource reservation, which uses RSVP (Resource Reservation Protocol) as a signaling protocol to establish channels and make resource reservations. Int-Serv uses an ATM-like SVC (switched virtual circuit) method, using RSVP as the signalling of each data stream between the sender and receiver, and every network along the way from receiver to sender Units must support QoS control mechanisms and reserve resources for each data flow that requires QoS. At the same time, the protocol also recommends the use of end-to-end signaling, so that QoS control information can be passed between network elements. ^[1]
