By looking at captured traffic that contains the condition in question and examining the datagram sizes. Certain types of traffic (malicious and legitimate) have certain minimum and/or maximum size characteristics, which are what you're after. Create the condition (or capture it in the wild), and look for a pattern. This is basically what you do any time you want to create a new signature.
