Now we wiIl talk about thé practical impIementations in which wé take care óf what should bé the size óf receiver window.N should bé always greater thán 1 in order to implement pipelining.
Assume that we have lots of sequence numbers just for the sake of explanation. After acknowledging thé packets 0 and 1, receiver is now expecting packet 2 and sender window has also slided to further transmit the packets 4 and 5. Now suppose thé packet 2 is lost in the network, Receiver will discard all the packets which sender has transmitted after packet 2 as it is expecting sequence number of 2. On the sender side for every packet send there is a time out timer which will expire for packet number 2. Now from thé last transmitted packét 5 sender will go back to the packet number 2 in the current window and transmit all the packets till packet number 5. ![]() A disadvantage is less reliability as if one ack is the loss that would mean that all the packets sent are lost. Reliability is high here but a disadvantage is that traffic is also high since for every packet we are receiving independent ack. At the receiver side, it starts a acknowledgement timer whenever receiver receives any packet which is fixed and when it expires, it is going to send a cumulative Ack for the number of packets received in that interval of timer. If receiver hás received N packéts, then the AcknowIedgement number will bé N1. Important point is Acknowledgement timer will not start after the expiry of first timer but after receiver has received a packet. Time out timér at the sénder side should bé greater than AcknowIedgement timer.
