Subject: [tsvwg] Linux TCP RTO

For the fellows not constantly following the Linux kernel maillinglist: we are currently try to adjust Linux's TCP RTO behavior to implement a RFC 6298 compliant calculation[1]:

We wrote an small document where we highlighted the current Linux implementation, validated our 6298 compliant implementation and presented measurements comparing both mechanisms:

Yuchung tested the modification in large scale at Googles web servers (HTTP,
HTTP2) and first results looks promising:

[1] some aspects of Linux differs too much to implement a 100% compliant RFC
