> TCP protocol will restart over with single packet when a packet gets lost rather than optimising for throughput. It will back off to an earlier window size. It won't just jump to 1 packet. As of 2010, the default initial window size is 10 packets across OSen, so it's unlikely to ever get to 1 packet unless you're on a really lossy network.
