[ns] Starting Trouble with SACK


Hi all,
 
I am new to NS. Hence any help is appreciated. I am trying to understand
the implementation of SACK on NS. I believe tcp-sack1.cc is the file I
have to look into. Can someone please help me with the basic
implementation detail - like how is the starting and ending seq numbers of
the SACK blocks sent and extracted etc. 

Thanks a lot!
