Dear all,
The client uploaded the file to a server, and I see there are many TCP Dup ACK from server to client. The SLE number is the same, but the SRE number is increasing. But I did not see retransmission in the client to server's packets. Please advise what does it mean?
And will dup ack also reduce the congestion window on the client-side? Please advise. Thank you!
