Here in Go Back - N :

N  refers to the senders window size

So window size here  =  127 as it is Go back - 127..

But we know  number of distinct sequence numbers for Go back N  =   max senders window size + 1 

                                                                                                  =    128

And starting sequence number    =    0..

Hence range of sequence numbers     =      0   to   127

Sequence number >= sws+rws for any protocol.. If you go through gbn rws=1 Therefore seq n >= 127+1 Therefore the range would be from 0 to 127
