Subject: Query on Acking Out of sequence data

Hi,

When TCP receives out of sequence data,
its required to send an
Immediate ACK (this is a Duplicate ACK).
If The TCP has pending
data to be sent, Can this data go along
with this immediate ACK?
Thanks
Praveen

No. A DUPACK must also be a pure ACK.

HI Reiner,
Is the SACK also a pure ACK? (Without
data, even though TCP has the pending
data to transmit).
Thanks
