Hi All,
I am sorry if this is kinda newbie question.

I am implementing the RFC 2001 and I want to know whether SACK and Fast 
Retransmit can coexist. Reading the RFCs has only landed me up in 
confusion. While fast retransmit will send the packet when it sees the 
third duplicate ACK, SACK will retransmit the all the packets after a 
retransmission timeout. If my fast retransmit packet is not ACKed 
before the retransmission timer times out, the same packet gets sent 
two times. That is my problem.

Any help is greatly appreciated.
Thanks for the patience.
