WebJul 11, 2024 · GBN protocol dictates that a sender should respond to 3 unique events: Application data received from the above layer (Application process); ACK received from the receiver; Timeout event for a previously transmitted packet The mechanics of GB are somewhat simple: a sender transmits a number of packets and waits on ACKs from the … WebThe sender maintains a timeout clock for each of the unacknowledged frame number and retransmit that frame after timeout. Acknowledgement will be piggybacked to the sender. But when there is no traffic in the reverse direction, piggyback is impossible, a special timer will time out for the ACK, so that the ACK is sent back as an independent packet. tree spa fig tree farm
