This In the near future there will be demand for seamless service across different types of network, so it‟s a significant issue of how to guarantee the quality of service (QoS) and support a variety of services. The challenges of new communication architecture are to offer better quality of service (QoS) in internet Network. A large diversity of services based on packet switching in 3G network and beyond 3G leads dramatic changes in the characteristics and parameter of data traffic. In this paper we propose uses of RSVP protocol for real-time services to guarantee the QoS in heterogeneous networks. The uses of RSVP protocol in a different internetworking scenario and mobility management have been extensively discussed over the last decade [1]. As a resource reservation mechanism, the Resource Reservation Protocol (RSVP) faces a lot of challenges when applying it to wired, wireless, and Mobile Network. Through this paper packet end to end delay and packet delay variation is evaluated over variable bandwidth through simulation. Results are compared with and without using RSVP. Result shows with the uses of RSVP, it has better quality of service in a voice based and Video based services. Simulation is done using OPNET.
