To help me make this paper more relevant to your needs, could you tell me:
) before needing an ACK. If a frame is lost, the receiver discards all subsequent frames, and the sender must retransmit all frames starting from the lost one. Better utilization than Stop-and-Wait. Cons: High retransmission overhead in poor channels. 3.3. Selective Repeat ARQ (SR) To help me make this paper more relevant
Low throughput on links with high propagation delay, as the channel remains idle while waiting for ACKs. 3.2. Go-Back-N ARQ (GBN) the receiver discards all subsequent frames
Requires complex buffering and ordering at the receiver. 4. Performance Considerations To help me make this paper more relevant
