Re: Identifying submarine links via traceroute

[Mehmet Akcin <mehmet () akcin net>]

Nice challenge.

Check out infrapedia.com where you can see length of cables and this may
help you “guess” latency but given so many cables are within 5-10ms in some
paths there may be  false positives

A very good topic to work on.
