Fast retransmit and fast recovery

WebIn TCP/IP, fast retransmit and recovery (FRR) is a congestion control algorithm that makes it possible to quickly recover lost data packets. Without FRR, the TCP uses a timer that requires a retransmission timeout if a packet is lost. What causes TCP fast retransmission? TCP Analyze Sequence Numbers. … WebMar 22, 2024 · 5. TCP fast retransmit/fast recovery If a sender receives several acknowledgements for the same packet, this is due to a gap in received packets at the receiver or missing acknowledgements The sender can now retransmit the missing packet(s) before the timer expires. This behavior is called fast retransmit. It is an early …
