WebNov 5, 2024 · Retransmission is needed to recover a missing packet that is assumed to have been dropped by a router due to congestion. Retransmission can occur in one of two cases: when the RTO timer times out or when three duplicate ACKs are received. Case 1 : Retransmission due to Timeout – In this case congestion possibility is high. http://intronetworks.cs.luc.edu/current/html/reno.html
