It would be interesting to see how one could use <a href="https://amarisoft.com/" class="external-link" target="_blank" rel="noopener">Amarisoft</a> to validate L4S efficiency in emulated environments.</p> <p> <img class="glightbox" src="https://qsysarch.com/images/resilient-networking/l4s.webp" alt="" /> (image source: <a href="https://www.nokia.com/bell-labs/research/l4s/" class="external-link" target="_blank" rel="noopener">Nokia Bell Labs</a>)</p>
