Rama.annareddy@gmail.com Abstract RSVP is a receiver oriented reservation protocol being an Internet standard approved by Internet Engineering Task Force [IETF].The goal of the Resource ReSerVation Protocol (RSVP) is to establish Quality of Service information within routers and host computers of the Internet. High speed networks support use of dedicated resources through Resource Reservation Protocol (RSVP). With RSVP, the network resources are reserved and released there by providing a mechanism to achieve a good quality of service (QoS). This requests to reserve a path are transmitted in the network b/w the data senders and receivers. This paper provides an analysis of the RSVP protocol used in peer- to-peer networks where each system works simultaneously as client and server. This experimentation for Audio and video conferencing application in various scenarios implemented in OPNET software. This RSVP protocol reduces the packet end-to-end delay. KEY WORDS: - RSVP, QoS, OPNET. I. INTRODUCTION Resource ReSerVation Protocol (RSVP) is a receiver oriented resource reservation setup protocol designed for Integrated Services Internet. RSVP has a number of attributes that make it be adopted as an Internet standard approved by Internet Engineering Task Force (IETF) [1]. These attributes include scalability, robustness, flexibility, dynamic group membership, and stability for multi cast sessions, support for heterogeneous receivers, and varieties of reservation styles. However, the RSVP designed for fixed network has been facing a great challenge due to the participation of mobile hosts. An inter network[2] is a collection of individual networks, connected by intermediate networking devices, that functions as a single large network. Internetworking refers to the industry, products, and procedures that meet the challenge of creating and administering internetworks. Fig:1 illustrates some different kinds of network technologies that can be interconnected by routers and other networking devices to create an internetwork. Implementing a functional internetwork is no simple task. In this paper, we perform a comparative analysis of the working of RSVP protocol in conjunction with multimedia applications including audio and video conferencing. We use a peer-to-peer based network in which each system acts as a client and a server. The reservation messages are generated by the hosts and depending upon the flow of data, some of the requests are accepted. Consequent to the reservation of network bandwidth, the network performance of the considered application improves. For the analysis of RSVP protocol, we use the metrics of the RSVP control traffic generated and the packet end-to-end delay. Our simulation has been performed using the OPNET IT Guru Academic Edition v 9.1 (OPNET, 2011). 60 INTERNATIONAL ASSOCIATION OF ENGINEERING & TECHNOLOGY FOR SKILL DEVELOPMENT 2nd INTERNATIONAL CONFERENCE ON CURRENT TRENDS IN ENGINEERING RESEARCH ISBN : 378 - 26 - 138420 - 6 www.iaetsd.in
