This document advances the F-RTO algorithm previously published in
RFC 4138 from Experimental to Proposed Standard. The changes from
RFC 4138 are described in an appendix, but mainly consist of
clarifications. This document only upgrades F-RTO for TCP from
Experimental to Standards Track; F-RTO for SCTP remains an
