[e2e] Question about RFC 2581

Correction to the previous posting -

Equation 4 should be 
      cwnd += min(bytes_acked, SMSS)* SMSS / cwnd          (4)

This is (almost) equivalent to the byte-counting method described in RFC
2581.

Equation (3) remains unchanged -

      cwnd += bytes_acked * SMSS / cwnd                     (3)

Also, with equations (3) or (4), the rate of growth of cwnd is (slightly)
smaller, when there are more (partial) ACKs per segment, which is probably a
good thing.

Regards,
Anil
