Abstract

Providing guaranteed Quality of Service in the current internet has become extremely essential to fulfill the requirements of current internet services. With increase in the number of users and demand for real time applications like video streaming, VoIP, audio video conferencing there is high demand for larger bandwidth for these applications. Many schemes have already been put forth and implemented for such real time applications but with some disadvantages. The project proposes integrating of the IP multicast over MPLS with different Quality of Service QoS techniques to guarantee essential QoS parameters like the bandwidth, delay, and through put. The project implements a non-traffic engineered approach using Label Distribution Protocol (LDP) instead of Resource Reservation Protocol (RSVP) as RSVP has scalability issues when it comes to real time video conferencing application. The network so designed has been simulated using the simulation tool OPNET modeler. The results obtained from the simulation clearly show that use of IP multicast over MPLS while using different QoS techniques has better performance in terms of bandwidth, throughput and delay when compared with convention IP data transfer approach.
