1. 1 Third Frontier Network Measurement Project Mark Cain, Cincinnati State Prasad Calyam, OARnet Joint Techs Workshops, Columbus, OH, July 19 th, 2004

2. 2 Overview History Project Motivations Goals and Partners Work in Progress… End-to-End Performance Case Study Conclusion

3. 3 History Concept paper “Learning on Demand for All Ohio Citizens: Building Ohio’s Video Intranet” http://www.oln.org/conferences/OLI2000/pdf/OVI_vision.pdf

4. 4 Project Motivations The Third Frontier Network (TFN) funded by the Ohio Board of Regents A dedicated high-speed fiber-optic network linking Ohio colleges and universities with research facilities to promote research and economic development Over 1,600 miles of fiber have been purchased to create the network backbone in Ohio to connect colleges and universities, K-12 schools, and communities together

5. 5 Project Motivations (Contd.) “TFN Measurement Project” was proposed in late 2003 To ensure that University campuses can effectively use the advanced networking services the new network provides Project funding from the Ohio Board of Regents

6. 6 Partnering Institutions OARnet (Project Lead and Co-ordination) University of Cincinnati Cincinnati State The Ohio State University Kent State University Southern State Community College University of Toledo Wright State University

7. 7 Project Goals Identify end-to-end performance bottlenecks in TFN by building a comprehensive Network Measurement Infrastructure (NMI) Test new and advanced technologies and equipment before wide-scale adoption in the TFN Higher Education communities Technologies: H.323/SIP based Voice and Videoconferencing, MPEG3, HDTV, Multicast, Bulk FTP Equipment: Video streaming Caches, Firewalls, Intrusion Detection Systems, Traffic shapers Bring awareness and train campus-networking professionals to make optimum use of the capabilities of TFN so that their campus network infrastructures can be upgraded suitably

8. 8 Work in Progress… Most of the equipment required for the testing has been procured by various partners Commercial network monitoring packages appareNet, NetQoS Other Equipment Starbak video streaming servers and caching appliances Polycom Viewstations, Via Video, etc… Cisco PIX firewall blades, etc… Vector Packet Shaper Measurement Servers and Praecis Ct time sources

9. 9 Work in Progress… (Contd.) Video and Voice over IP Testing Traffic performance characterization studies Using various codecs: audio and video Via various intermediate devices (Firewalls, Packet Shapers, …) Under various network conditions (delay, jitter and loss) Testing both in LAN and Internet Portions of the results of above studies presented at the Passive and Active Measurement Workshop, France, April 2004 http://www.cl.cam.ac.uk/Research/SRG/netos/pam2004/papers/222.pdf

10. 10 Work in Progress… (Contd.) Case studies and best practices for H.323 Videoconferencing Using H.323 Beacon tool features Paper to be presented at the ACM SIGCOMM Network Troubleshooting Workshop, Portland, Oct 2004 http://www.itecohio.org/beacon/h323beacon_sig.pdf Planning currently underway for: Evaluating video streaming cache performance Bulk FTP transfer performance

11. 11 Work in Progress… (Contd.) Network Measurement Infrastructure Comprehensive toolkit for measuring various network performance parameters Using open-source and commercial measurement tools Enhancing H.323 Beacon tool, developed by OARnet and supported in part by Internet2 Deploying Netflow tools developed at OSU and OARnet at various campus and network backbone locations Building a weather map for routine TFN monitoring Pilot deployment of a measurement testbed at UC and OSU via OARnet backbone End-to-End Performance Case Study To be expanded to cover entire TFN backbone
