A while ago we looked at our spine and got an average size of 144
in one case, 153 in another. I have the cunts for each protocol, etc
by host, so if you wnat more info, I got it...

For example, the traffic going out to the ARPAnet was 141 bytes (23%
of the total packets counted). 

For telnet, the average was 60, 
for FTP control 55, for FTP data was 293 (average of data plus ack,
remember) 

for mail, 101. (Either its silly transfer mode, or the control swamps
the data phase.) 

This spine on that day did not carry NFS. That would skew it a great
deal. There was a block oriented disk access protocol running that day
with an average size of 299. 

But none of these are up near 700.
