What Is NDT?
NDT is the Network Diagnostic Tool, developed by Rich Carlson
of the Department of Energy's Argonne National Laboratory. It
can be accessed via: http://miranda.ctd.anl.gov:7123.
For a recent presentation on this tool, see: http://www.internet2.edu/presentations/spring03/20030410-Web100-Carlson.htm.

t
is a cakebox? It is a small, inexpensive PC
running Linux. It is configured such that, when you plug it
into a DHCP-enabled Ethernet port and give it power, it registers
its presence with an LDAP server where it logs its current
IP address so you can “find” it. You can then
connect to it remotely and run a series of network utilities
(like Iperf, traceroute, and pchar). Cakeboxes were developed
by Internet2 to test H.323 video conferencing capabilities
and have been used for a variety of other end-to-end performance
tests. Instructions on “building” a cakebox are
available to member institutions upon request.
