Opnet Simulator Project
                                 Spring 2001
  Midterm Presentation

  Student: Avi Yadgar
  Supervisor: Yoram Yihyie
Project Goals

   Implementation of a simulation environment
    for a known protocol, using as many of the
    simulator’s features as possible, according
    to the modeling paradigm.

   Composition of a detailed user guide in
    Hebrew, on the basis of the implemented
    environment.
Project Goals, cont’

   Modification of the simulated protocol
    using the software’s low level features.

   Comparative performance evaluation.
What is Opnet?
   A simulation and analysis software for:
    – Applications
    – Protocols
    – Architecture                            Hierarchy
                                             is the key!
    – Devices

                        Hierarchy
                        is the key!
A quick review

 Various probing
  possibilities
 Various output
  methods
Are you trying to sell something?

   Not really, just to present
    the tool and the modeling
    paradigm.
Where are we heading next?
 Completion of an environment for
  simulating multi server video on
  demand movies library based on the
  common TCP/IP protocol
 Modification of the TCP/IP protocol in
  order to achieve better results for
  this specific application
