Usually spoken on top of the Internet Protocol (legacy version 4 or version 6), it provides a reliable, ordered, and error-checked stream of octets. When an application uses TCP, they get these properties for free (in contrast to UDP).&lt;/p&gt;
&lt;p&gt;As common for Internet protocols, also TCP is specified in a series of so-called requests for comments (RFC), the latest revised version from August 2022 is &lt;a href=&quot;https://datatracker.ietf.org/doc/html/rfc9293&quot;&gt;RFC 9293&lt;/a&gt;, the initial one was &lt;a href=&quot;https://datatracker.ietf.org/doc/html/rfc793&quot;&gt;RFC 793&lt;/a&gt; from September 1981.&lt;/p&gt;

&lt;p&gt;We'll take some more time to investigate issues of µTCP in production, plan to write further documentation and blog posts, and hopefully soon are ready for an initial public release. In the meantime, you can follow our development repository.&lt;/p&gt;
&lt;p&gt;We at &lt;a href=&quot;https://robur.coop&quot;&gt;robur&lt;/a&gt; are working as a collective since 2018, on public funding, commercial contracts, and donations. Our mission is to get sustainable, robust and secure MirageOS unikernels developed and deployed. Running your own digital communication infrastructure should be easy, including trustworthy binaries and smooth upgrades. You can help us continuing our work by &lt;a href=&quot;https://aenderwerk.de/donate/&quot;&gt;donating&lt;/a&gt; (select robur from the drop-down, or put &amp;quot;donation robur&amp;quot; in the purpose of the bank transfer).&lt;/p&gt;
&lt;p&gt;If you have any questions, reach us best via eMail to team AT robur DOT coop.&lt;/p&gt;

&lt;h2 id=&quot;deploying-mirageos-unikernels&quot;&gt;Deploying MirageOS unikernels&lt;/h2&gt;
&lt;p&gt;More than five years ago, I posted &lt;a href=&quot;/Posts/VMM&quot;&gt;how to deploy MirageOS unikernels&lt;/a&gt;. My motivation to work on this topic is that I'm convinced of reduced complexity, improved security, and more sustainable resource footprint of MirageOS unikernels, and want to ease deployment thereof. More than one year ago, I described &lt;a href=&quot;/Posts/Deploy&quot;&gt;how to deploy reproducible unikernels&lt;/a&gt;.&lt;/p&gt;
