Hi ,
       As per RFC 2961
         "Out of order messages SHOULD be ignored, i.e., silently dropped."
       If Epoch value of the message is same and new message id is less than
the old one , then message is out of order and hence
it should be dropped .
  For message Id wrap cases ::
"
if ((int) old_id - (int) new_id > 0) {
          new value is less than old value;
       } "
    How you will you differentiate between wrap case and normal out of order
case , since in both cases new message Id will be less than old message ID
and epoch is same .
