since in first link 954 bytes are transferred,why are we considering only 920 for next link??
and while you are calculating last fragment,you are writing that last fragment is 440+20+12 in which data is (440+20) =460 bytes,but data part here is just 440 (i am confused that whether it should be 460 or 440)and while calculating offset,you took just 480 not (480 + 20).pls explain this
and one more doubt i have,when divind further i should consider data + header into consideration or just data part??
Thanks for the help
