Silly Window Syndrome

Posted by AJ × 10:20

Situation:

v Transmitter sends large amount of data

v Receiver buffer depleted slowly, so buffer fills

v Every time a few bytes read from buffer, a new advertisement to transmitter is generated

v Sender immediately sends data & fills buffer

v Many small, inefficient segments are transmitted

Solution:

v Receiver does not advertise window until window is at least ½ of receiver buffer or maximum segment size

v Transmitter refrains from sending small segments.
