Hello! This is the sixth report for TCP UTO. * Short TCP UTO description UTO stands for User Timeout Option (it is described in RFC5482). TCP UTO specifies a peer should be allowed to advertise its chosen `User Timeout' for a connection. The wiki page for this project: http://wiki.freebsd.org/CatalinNicutar/TCPUTO * Work completed last week * Retransmits are being sent at regular intervals (TCPTV_REXMTMAX) until the timeout runs out. This will probably be adjusted as sending data continuously to a possibly uninterested peer should be avoided * I have added two captures on the wiki page, showing the behavior with and without UTO (see link above) * My goals for for this week * Write tests for tools/regression and look for possible boundary cases * Add more examples to the wiki page (including a scenario with a very short timeout) * Try to get the Linux patch by Hagen Paul Pfeifer and test it with the current FreeBSD implementation * Consider adjusting the API so it's similar to the Linux patch (it will help adoption by more applications) * I will start changing tcp.4 as the API is becoming stable If you have questions, suggestions or advices drop me an email to cnicutar@FreeBSD.org.
