With a window size of 1, a misbehaving receiver might be able to anticipate packets injected into the network by the sender. The receiver could aggressively generate ACKs before data is actually received (bypassing typical delayed ACK mechanisms). This may be more of a problem for the sender if the rate of 1-byte ACKs is high. If the connection and receiver's address could be spoofed, bursts of 1-byte segments from the sender can be sent to an innocent victim as part of a tinygram DoS attack. John
