Hi all.
I have a question, not specifically related to LAN, but a little of all.. :-)
I was testing a WAN link today, by the means of different techniques.. One of 
them was to ping the IP address of the WAN interface of the remote router 
with different packet sizes, and measuring the round-trip time. We tested 
with compression ON and OFF on the WAN connection. Since we saw a great boost 
in response time between non-compressed WAN link and compressed WAN link, I 
just wondered if any of you know what kind of data is contained in a normal 
ping packet? Is it just zeroes, or ones, or a particulary compressable 
pattern?
Example: ping with 1018+44 bytes packets went round-trip on 54 ms on 
compression, and 301 ms on non-compressed link. This test was basically to 
test comression and delay of the link delivered by the PTT.
We also measured the time and quantity of data in a normal-use application, 
and saw improvements from non-compressed to compressed link.
