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
4
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
5
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
7
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
8
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

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

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
