<div dir="ltr"><div>Hello,</div><div><br></div><div>If you can estimate the packet loss on a link, you could use network coding to cover any % of packet loss, at a similar % increase in data usage and slight increase in latency. Let me know if you need more info, and I can dig up the info on the algorithm. It works great, for example, to get stable video over 3G networks that are notorious for packet dropping.</div><div><br></div><div>Paul.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, 6 Apr 2020 at 12:34, Aaron van Meerten <<a href="mailto:aaron.van.meerten@gmail.com">aaron.van.meerten@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;"><div>I don’t believe the encryption/decryption is all that resource intensive in comparison to the encoding and decoding of the video and audio streams themselves.</div><div><br></div><div>We have a few features to try to deal with this, including audio-only mode and the ability to send lower-quality video (Low bandwidth mode)</div><div><div><br></div><div>I do know we suffer from poor performance on connections for which packet loss/packet drops are common. </div><div><br></div></div><div>However, my role in the team (DevOps) is such that I won’t be able to speak very coherently about why that is or what specifically we do to handle this situations.</div><div><br></div><div>If you have specific questions about those features, you can ask on our community forums here:</div><div><br></div><div><a href="https://community.jitsi.org/" target="_blank">https://community.jitsi.org/</a></div><div><br></div><div>Our (fairly small) team does monitor these and tries to answer as best we can.</div><div>If you don’t get a response, feel free to ping me and I can try to poke the appropriate team member based on your question.</div><div><br></div><div>Cheers,</div><div><br></div><div>-Aaron</div><div><br></div><div><br></div><div><br></div><div><blockquote type="cite"><div>On Apr 4, 2020, at 4:10 PM, Jose Luis Mendoza Marquez <<a href="mailto:jluismendoza@gmail.com" target="_blank">jluismendoza@gmail.com</a>> wrote:</div><br><div><div dir="ltr"><div class="gmail_default" style="font-family:georgia,serif;font-size:small">And this represents a very big sacrifice of resources in the connection?
