Overview • History • Project Motivations • Goals and Partners • Work in Progress… • End-to-End Performance Case Study • Conclusion
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
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
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
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
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
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
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
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
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
Network Measurement Toolkit • Tools used for network performance data collection • Ping(Delay) Open Source • Traceroute(Topology) Open Source • appareNet (Hop-by-Hop Performance) Commercial • Iperf(TCP/UDP Bandwidth Performance) Open Source • Pathchar(Hop-by-Hop performance) Open Source • Pathload(Available Bandwidth) Open Source • Pathrate(Bottleneck Bandwidth) Open Source • OWAMP(Precise Delay) Open Source • H.323 Beacon (Voice/Video Performance) Open Source • NetQoS(Application Response Time)Commercial
