This thesis presents different Internet Protocol (IP) multicasting design models and together with their
implementation methods in OPNET Modeler 14.5. The models presented in this report are designed
for handling various types of advanced multimedia applications and services when using the multicast
communication paradigm. The architectural models presented in this thesis are independent of the
routing protocols used as well as of the underlying networking environment.
Several exiting challenges related to high bandwidth requirements, low network delay, and jitter are
discussed together with these design models, and are simulated using the OPNET Modeler. The
emerging demands for new multicast capable applications, for both real-time and non real-time traffic
are considered together in this report in order to better evaluate multicast traffic requirements.
Efficient routing methods, group management policies, and shortest path algorithms are also discussed
in the proposed models. The pros and cons of IP multicasting are described using the Protocol
Independent Multicast Sparse Mode (PIM-SM) method, in the highlight of the proposed design
Several results related to link utilization, end-to-end delay, packet loss, PIM control traffic, Internet
Group Management Protocol (IGMP), and network convergence are obtained by using already
available statistical methods and modules from OPNET Modeler. Our major contribution with this
thesis work relates to components associated with network convergence, routing delay, and processing
delay. These components are illustrated in this thesis using various OPNET metrics. Moreover, several
issues related to protocol scalability, supportability, performance optimization and efficiency are also
presented by using OPNET’s build in reports, i.e., executive flow and survivability analysis reports.
