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

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

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 FTPEquipment: 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 TestingTraffic 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

Work in Progress… (Contd.)

Network Measurement InfrastructureComprehensive 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
