Silly window syndrome is a problem in computer networking caused by poorly implemented TCP flow control. A serious problem can arise in the sliding window.[image] NEW: Check out our TCP Optimization Guide: Nagle Delays and Beyond Silly Window Syndrome (SWS) is a problem that can arise in poor.Silly window syndrome is defined as small amounts of TCP data (instead of maximum segment sized) packets being sent. This is avoided by: The receiver not.delay important data. ○ If TCP waits for a timer, then bad behavior can result. ○ Lots of small packets get sent anyway. ○ Silly Window Syndrome.SILLY WINDOW SYNDROME In order to understand SWS, we must first define two new terms.
