This document proposes an experiment to increase the permitted TCP
initial window (IW) from between 2 and 4 segments, as specified in
RFC 3390, to 10 segments with a fallback to the existing
recommendation when performance issues are detected.  It discusses the
motivation behind the increase, the advantages and disadvantages of
the higher initial window, and presents results from several large-scale
experiments showing that the higher initial window improves the
overall performance of many web services without resulting in a
congestion collapse.  The document closes with a discussion of usage
and deployment for further experimental purposes recommended by the
IETF TCP Maintenance and Minor Extensions (TCPM) working group.

This document is a product of the TCP Maintenance and Minor Extensions Working Group of the IETF.
