Windowing technique

____________________________________________

Windowing refers to the amout of data that a data sender is allowed to transmit without waiting for an ack. In this case, the size of the window is 2400 bytes, meaning that the data seder can transmit 2400 bytes before it has to stop and wait for an ack,

The data recipient decides the size of the window, not the sender. This gives the recipient some control over how much data is sent ("flow control").



The term sliding window refers to this dynamic adjustment of the window size.
UDP does not have windowing capabilities.
