 #### Fast Retransmission
 
-   For example, the sender has sent packets 1,2,3,4,5, then got the ACK message from peer 1,3,4,5. When got ACK 1,3, KCP will notice the packet 2 maybe dropped; when got ACK 1,3,4, the packet 2 almost dropped and KCP will directly retransmit packet 2 without wait for timeout. This algorithm can improve the transport speed when network is not very good and dropping some packets.
