LinkedIn Q&A: Hi everybody, could anyone explain me how High-Speed TCP works and what are the differences between HS-TCP and TCP standard?

Congestion control is much more aggressive in HS-TCP (RFC 3649, experimental) than in TCP.

Whenever congestion occurs on an HS-TCP connection, the window size is not halved like it would be with TCP: it is only reduced by a small amount and then increased again quickly.

This allows HS-TCP to deliver more stable and more consistent throughput on very high speed links.
