Dave Mills has been seeing asymmetric routing for traffic between the
University of Delaware and the fuzzball NTP server in Norway.  Dave,
please correct me if I'm wrong but I believe you said that traffic
from UDel goes to Princeton and then to Stockholm, while traffic from
the fuzzball in Norway goes down a link to Amsterdam and over the
UUNet link to Maryland.

Can anybody verify this?  Explain it?  Justify it?  Asymmetric routes
aren't necessarily bad, but we should know why they are happening
because they are often indicative of problem areas in routing.

						Thanks ... Scott
