ANALYSIS OF RESOURCE RESERVATION PROTOCOL (RSVP) FOR P2P NETWORKS

Abstract

High speed networks support use of dedicated resources through Resource Reservation Protocol (RSVP). With RSVP, the network resources are reserved and released thereby providing a mechanism to achieve a good quality of service (QoS). The requests to reserve a path are transmitted in the network b/w the data senders and receivers. The reservation request is then accepted depending upon the availability of resources. With dedicated resources for a data flow, the network performance improves especially for the communication sensitive to delay. This paper provides an analysis of the RSVP protocol used in peer-to-peer (P2P) networks where each system works simultaneously as a client and a server. We perform experimentation for Voice and Video Conferencing applications incorporated in various scenarios implemented using OPNET IT Guru Academic Edition v 9.1. Our experimentation results show that the RSVP protocol reduces the packet end-to-end delay, however, the impact is dependent upon the amount of data being transmitted along the reservation path.
