... Because all packets are lost, we only detect loss through a timeout. This causes the sender's window to be reduced to a single MSS (1000 bytes / RTT), at which time it enters "slow-start restart". Namely, it will perform slowstart until half of its prior cwnd (16,000 bytes/second), then do additive- ...
