TTM plots NCC->SARA for oct'99, may & aug 2000
Hi,
While working on the software for our upcoming TTM plots-on-demand
service, I created some plots covering three 7 day periods in Oct'99,
May'00 and Aug'00 for the connection RIPE NCC -> SARA (surfnet)
The results are in /home/wilhelm/TestTraffic/NCC-SARA:

/home/wilhelm/TestTraffic/NCC-SARA/tt01.tt13.may2000.gif
/home/wilhelm/TestTraffic/NCC-SARA/tt01.tt13.aug2000.gif
(and corresponding .ps files).
It is clear to see the situation in May (just before things started
to collapse) had already detoriated with respect to half
a year before.
Also, as far as delays are concerned, the present situation is as
good as we've never seen before in the past 12 months.
The only thing which seems a bit worrying, is the ~1% packet loss
we now detect. The bottom left graph in the aug2000 plot, clearly
shows this started after the maintenance in the evening of July27,
when our service LAN @nikhef got reconnected to pampus.
Hmm, time to bring in faster Ciscos? :-)
