Questions about fast retransmit

Hi, two little questions:

1) What happens to twnd during fast recovery? From what I understood it stays at 1/2 of its original size and when fast retransmit is over cwnd is set again to twnd (thus decreases). Is this correct?

2) What happens when we reduce a window and for example all the packets in the window have already be sent (thus sent packets will be out of the window...)

Thanks for the help,

Christophe Gudin.

1) yes, look e.g. at figure 2.6 in cc.pdf
2) nothing special, the algo runs as before
