Gbn ack
WebThe ACK number, like NAK (negative acknowledgement) number, shows the number of the frame, that receiver expects to be the next in sequence. The window size of the receiver is 1 as the data link layer only require the frame which it has to send next to the network layer. The sender window size is equal to ‘w’. WebGBN is resending ACK's for the discarded packets . Excerpt from what I can find: The receiver's actions in GBN are also simple. If a packet with sequence number n is …

Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively.
