What Is NDT?

It is the Network Diagnostic Tool, developed and expanded under several government grants. The NDT is a component of the E2Epi's piPEs effort; it provides the 'last mile' diagnostic component to the suite of tools offered by the piPEs measurement infrastructure. For more information on NDT, see http://e2epi.internet2.edu/ndt/.

Back to Case Study

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.
