Hello, My apologies for the specialists and and experienced OM. I don't understand : - What's the connection between Amprgw, Caida and USCD/NT? - Where can I find information about the structure of Amprgw

We've identified the problem ... when amprgw is rebooted, ... the Ethernet switch it's plugged into crashes.
Hello Brian,
1. What is the exact current network configuration for Amprgw/NT?[1][2] 2. Which make/model of switch exhibiting the problem?
Cheers, -Paul
[1] Reviewing the diagram at:
https://www.caida.org/funding/stardust/stardust_proposal.xml#tth_sEc4.1
shows 'amprgw' ("Non-profit Router", on diagram) and 'seaport' ("Capture Server", on diagram) being optically paralleled from the same ethernet switch. Where an outage of the switch should affect both equally. (ie. is the diagram up-to-date?)
[2] Reviewing the UCSD/CAIDA Network Telescope bandwidth graphs at:
http://www.caida.org/data//realtime/telescope/?monitor=telescope_attack&...
does not appear to show an outage/interruption in the in-flow of packets being captured.
