6.02 - Network: Reliable Transport and Congestion Control

- In fact, when a packet is lost due to timeout, TCP behaves differently: W = 1, then do slow-start until the last good window, and then start additive increase. - (See slide for diagram) - Reasoning: if there is a retransmission due to timeout, then there is significant loss in the network, and senders should back *way* off. 9.

wait a specific period (called retransmission-time-out (RTO)) to retransmit lost packets, attacking hosts can flood packets at the next RTO to disrupt retransmission. Thereby, attacking hosts can synchronize their flooding at the following RTOs and disable legitimate TCP connections as depicted in Figure 2.
