Campus NDT Server

Rich Carlson (ANL) has written a wonderful web100-based network diagnostic tester (NDT).

We've recently deployed a UF-based NDT server, which is available at

Use it to test the speed of your broadband or UF Internet connection, or check for a duplex mismatch -- it even identifies faulty NICs and network cables.

Information on IPv6 at the University of Florida.

UF recently hosted an Internet2 IPv6 Workshop (which I helped coordinate) in April of 2002.

Network Monitoring at UF

I am in charge of distributing rackmount Linux boxes around UF's core network in order to record various
network statistics. We currently record ping and nttcp stats at regular intervals, but would like to see iperf
stats in the near future. See the qlog page for more info.

We were invited to join Network World's Test Alliance in June of 2002.

SC Global

In November 2001, I was the network monitoring coordinator for SC Global.

SC Global is back for 2003, and I am participating as an at-large committee member concentrating on network-related issues.
