Performance study of IP over SONET

One of the biggest opportunities for service providers today is to provide IP based internetworking services to meet the exponential growth in demand from both business and residential customers. IP is designed to be transparent to the topology of the underlying transport protocol. With this opportunity, come a number of issues that must be resolved in order to meet the capacity requirements and deliver services in cost effective and revenue generating manner. The Internet traditionally provides service that is commonly characterized as a best effort service. This architecture has been tremendously successful in supporting data application like WWW, e-mail, FTP and HTTP. Many application run very well using this service model but some new interactive applications as telephony or video conferencing impose stringent demands to the network. In this project the computer software package OPNET modeler has been used to examine the dynamic IP traffic over SONET using PPP (point to point protocol) and IP over ATM under the real time application and nonreal time application.
