NNStat statistics.

I'd like to have at least the following statistics from the packets
coming from or going to nsf-gw and icm-gw. Statistics for intranordic
traffic would be only partial and not very usefull to be mixed with
outside traffic except for special cases like broadcasts and
multicasts for routing and vitalink managements.  For DECNET/HEP/SPAN
statistics you could count packets to and from SEGBOX and for IXI
packets to and from SeMega. Similar hourly and monthly periods would
be best for all of these so that they are comparable.

VMNET is a special case in which you really can make also intranordic
statistics by watching traffic in and out searn. This could be used to
see the real byte counts instead of missleading record counts you get
from RSCS. Fluctuation per hour could also be nice.

Distribution between different protocols above IP
like smtp, ftp, telnet, rlogin, Xwindows, nntp, vmnet,
ntp, igrp, snmp, irc, rfc1006, wais,ICMP (source quench and
unreachables separately?) etc.  A total packet and byte count for
these each month as well as by hour (or 15minute) average for working
days and holidays (weekends is enough) to see the changing patterns
and directions versus time of day.

Packet size distribution in general and as a special case for some protocols
could be of some interest too.

Top ten lists of hosts for the IP applications would also be nice but they
should also have in and out separately. The percentage of the total traffic
and capacity would help evaluating the significance.

Top hunred pairs of IP hosts is of less interest but might reveal something
usefull for some protocols like telnet or ftp.

The setup should be easy to port to other nnstats if we would like to set
up something in FUNET to monitor our NORDUnet traffic for example.
