Selective-Repeat has a small sending window but is more reliable Since the field that stores the sequence number of a packet is limited in size, the sequence number in a protocol needs to wrap around, which means that two packets may have the same sequence number. sango fighter download

WebTCP is similar to GBN because both protocols have a limit on the number of unACK'd packets that the sender can send into the network. However, TCP is different from GBN because GBN requires the re-transmission of every unACK'd packet when packets are lost, but TCP only retransmits the oldest unACK'd one. TCP is similar to selective repeat ... WebAug 5, 2024 · At N=1, Go Back N is effectively reduced to Stop and Wait, As Go Back N acknowledges the packed cumulatively, it rejects out-of-order packets, As Selective Repeat supports receiving out-of-order packets (it sorts the window after receiving the packets), it uses Independent Acknowledgement to acknowledge the packets. @Himanshikalra.
