analyse tcpdump output

Hi,

I wonder if someone knows a tool to use a tcpdump output for anomaly 
dedection. It is sometimes really time consuming when looking for identical 
patterns in the tcpdump output.

It would be helpful to get  a diff between SYN and ACK's e.g. Or look for  a 
pattern in a URL. Or just get some timediffs e.g. when an ACK is send but 
client is waiting for data etc.

We would like to decrease time to investigate the cause for an unusual network 
behaviour.

Best Stefan
