silly window syndrome 


Silly window syndrome is a popular term for a computer networking problem caused by poorly implemented TCP flow control.

The problem can arise in sliding window operations when the transmitting program creates data slowly, or the receiving program consumes data slowly, or both. If a server with this problem cannot process the incoming data, it asks its clients to reduce the amount of data they send in a block (the “window” setting on a TCP packet). If the server still cannot process the incoming data, the window becomes smaller and smaller (shrinking to a “silly” small value), sometimes to the point that the data transmitted is smaller than the packet header, making data transmission extremely inefficient.

Obviously, this is not a real syndrome; nonetheless, it appears to fill a lexical void.
