The retransmit timer was only stopped when all in flight data was acknowledged and never updated on individual acknowledgements. This caused a lot of erroneous retransmits whenever the buffer was filled fast enough so that the acknowledgements never caught up, i.e. whenever uploading or streaming data. Move setting of the initial retransmit timer inside the send loop so it is closer to the actual time the segment is sent out and simplify the logic a bit. Limit the minimal retransmit timeout to 200 msecs to avoid spurious retransmit in the face of delayed acknowledgements. This is lower than the 1 second minimum the RFCs suggest. Other stacks use various other sub-second timeouts, the 200 msecs follows what Linux does. Also add the exponential back off of the retransmit timeout when retransmits are triggered. This is bounded by a 60 seconds maximum according to RFC6298.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
