Re: [ippm] Testing TCP Throughput Capacity in Operator Networks

[Matthew J Zekauskas <matt at internet2.edu>]

My thoughts are similar to Henk's.  IPPM has always been interested in
the area (see the bulk transport capacity work), so I'd claim the area
is in-scope, but doing work would require AD discussion.

I think Matt Mathis' last message to the list is also worth thought;
it's hard to create a good metric.  In some sense what has been proposed
is documenting current practice (we do something similar for quality
control on the R&E networks, and NPAD is used for debugging).

I cannot be in Hiroshima do to a conflicting conference, but look
forward to the results of any discussion there.
