Professional Experience
Internet2 (University
Corporation for Advanced Internet Development), Ann
Arbor, Michigan (formerly
of Armonk, New York),
2001 – 2006
Internet Engineer/Network
Services Group. Provided engineering support and advanced Internet
services for
national projects, including Abilene,
Internet2’s 10Gbps national backbone network.
- Led technical planning and implementation for 36 highly-rated
hands-on advanced networking workshops over 5 years. Specified,
acquired, installed, configured and maintained traveling workshop lab
of Cisco router, Juniper routers, Digi terminal servers, and
Intel-based laptops running Linux. Prepared and presented IPv6
workshop content.
- Configured IP multicast access grid "beacon" environment in a
closed environment to support hands-on engineering workshops.
Installed and configured beacon clients in infrastructure of eight
Linux systems, reporting to a Linux-based beacon server.
- Coordinated demonostration of first North
American IPv6 multicast implementation on a production backbone network.
Implemented multi-platform and multi-operating system demonstration
with five end-points. Installed and configured dBeacon (open-source IPv4/IPv6
multicast network reachability tool), VLC
video clients, DVTS (Digital
Video Transport System) clients and Microsoft Research Conference XP
clients.
- Installed and configured Nagios/Netsaint
on Debian Linux system to
support accessibility monitoring of network systems.
- Configured and maintained IPv6-enabled
informational web server running Apache
version 2 on a Debian Linux
system. Maintained virtual web servers,
CGI and PHP scripts.
- Prepared responses to optical
fiber
acquisition RFPs from research
and education institutions as a member
of FiberCo, an Internet2 LLC that negotiated the sale of more than
10,000 fiber miles and set an aggressively low price point for fiber
acquisitions by the research and education community. Required
in-depth technical knowledged of long-reach optical fiber characteristics, optical
fiber infrastructure designs, and optical fiber network provider
support systems.
- Developed a network measurement analysis system using PHP and MySQL. System retrieved
measurement data stored in BML
format, made comparisons of network traffic and presented results on
HTML web pages.
- Evaluated network technology and
participated in the deployment of a 10Gbps nationwide backbone network. As a member of the Abilene Next Generation
planning team, evaluated network measurement equipment and prepared
test plans.
- Provided feedback to developers on open-source network
performance tools (such as iperf,
ssmping and access grid beacon).
- Facilitated IPv6 and IP Multicast
working groups.
- Acted as liaison for Internet2
Technical Evaluation Centers (ITECs) 2001 – 2003.
Advanced Network
& Services, Armonk,
NY, 1996 – 2001
Senior Internet
Engineer/Network Measurement Group.
Planned and supported a nationwide network measurement
infrastructure,
provided network analysis and planning for high-performance video
applications,
and supported research and education wide area network connectivity.
- Tested Quality of Service (QoS)
capabilities utilizing Cisco enterprise-class and campus-class routers
across a test network at the Internet2 Technology Evaluation Center
(ITEC) facilities in Research
Triangle Park, North Carolina.
Co-authored test plan, results document and summary document.
- Contributed to the planning of scope,
projects and focus of Internet2 Techology Evaluation Center (ITEC) in North Carolina.
- Executed end-to-end network throughput
tests, isolated defects in testing tools, identified campus network
problems and documented operating system network limitations and tuning
in support of a successful high-bandwidth, multi-site Tele-immersion
demonstration headed by virtual reality frontier Jaron Lanier.
- Participated in the design and
deployment of an infrastructure (called “Surveyor”) of computer
systems. Measured network one-way
delay and loss of the Internet among
universities and research institutions within the United States
and internationally.
- Coordinated, deployed and maintained
technical implementation of Advanced Network’s 155-Mbps POS connection to
the Abilene/Internet2 research and education network and the
“downstream” 45-Mbps connection to the research division of a large
computer company.
