    1. Implementation and simulation of Scheduling Algorithms in OPNET Project by: Itamar Cohen Supervisor: Nir Arad

    2. AGENDA Introduction Applications Algorithms: RR, WRR, WFQ Summary

    3. MOTIVATION Scheduling algorithms are used in: Computer networks, operating systems, real time applications.

    4. MOTIVATION (cont.) Uses for nowadays networks: Suppliers of services are committed to guarantee a fixed service level, which can be checked under a few pre-defined parameters. This is called SLA (Service Level Agreement). But the client would like to get much more A possibility to choose his favorite application, which will get a higher percentage of his bandwidth. This is called QoS (Quality of Service).

    5. SCHEDULING ALGORITHMS Plenty of algorithms try to solve in different ways the problem of one server, which has to choose in real time the next client to be served, among a few clients. Each algorithm is good for some case, but bad for other cases. No algorithm is good for all the possible scenarios. The OPNET modeler gives us an excellent ability to test each algorithm under plenty of different scenarios.
