Technical Summary
HighSpeed TCP modifies the congestion control mechanisms of TCP to accommodate
large congestion windows tailored to high-speed networks. Standard TCP constrains
the congestion window that can be achieved by TCP in realistic multi-gigabit
environments. Accordingly, HighSpeed TCP adapts the congestion window much more
appropriately to achieve an optimal steady-state for very rapid data transfer,
and does so in a way that can co-exist with standard TCP deployments on the
Internet.
Working Group Summary
The TSVWG Working Group supports the advancement of this Experimental protocol.
Several proposals to address the use of TCP in high-speed networks have arisen
outside the IETF (largely in academic communities); it is believed that the
experimental deployment of HighSpeed TCP will aid significantly in determining
the direction of ongoing research in this area.
