  1. Available Bandwidth Measurement Using Real Time Operating Systems Dennis S. Knoop

  2. Proposal The goal of this project is to study the effectiveness of using a Real Time Operating System to improve the accuracy of network measurement.

  3. Historical Background • BPrope and Cprobe developed by • Tool uses ICMP echo request • UCCS students, under the supervision of Dr. Chow, have modified the available bandwidth tool • Sending time gaps are still a problem

  4. Project Plan • Analyze current ABWM Tool • Research Real-Time Operating Systems • Load Real-time operating system • Port current ABWM Tool to RTOS • Analyze results

  5. Real Time Operating Systems • Basic Concepts

  6. UC/II • Strengths • Weaknesses

  7. RTLinux • Strengths • Weakneses

  8. RTLinux • Basic Concept • Modules • Scheduling • Threads

  9. ABWM Tool • Original Tool • Analysis • Improvements needed • Timing of initial time gaps • Re-Engineering/Port needed

  10. RTABWM Tool • Modification Made • Critical Code • Accuracy of results

  11. Linux Schedulers • SCHED_OTHER • SCHED_RR • SCHED_FIFO

  12. Comparison of Results

  13. Current Status • Analyzed current ABW Tool • Research Real Time Operating Systems • Chose RTLinux as RTOS of choice • Loaded RTLinux on viva.uccs.edu server • Ran sample/example programs • Working on Port of ABW Tool to RTLinux

  14. Conclusion • Result of testing • Future Work • Questions?
