How to stop sending data after received ack
Web– Sender cannot send packet i+N until it has received the ACK for packet i • Receiver operates just like in Stop and Wait – Receive packets in order – Receiver cannot accept packet out of sequence – Send RN = i + 1 => ACK for all packets up to and including i • Use of piggybacking WebMay 3, 2016 · However for some reason, I get a stop condition immediately after the read request (see below).

WebIn a pure cumulative acknowledgment protocol, the receiver can only send a cumulative ACK value of 2,000 (the sequence number immediately following the last sequence number of the received data) and cannot say that it received bytes 3,000 to 10,999 successfully. Thus the sender may then have to resend all data starting with sequence number 2,000. WebFeb 13, 2016 · The data frame is always 8 bits long, and sent with the most significant bit first. Each data frame is immediately followed by an ACK/NACK bit to verify that the frame has been received successfully.
