I think I've finally got the new relativistic timeline 100%. This has been one of the most difficult things I have ever debugged. The weaker causal consistency constraint means nothing is ever quite the same between client and server, so I can't really tell something has gone wrong until 3 to 20 frames after the bug. There's no guide for what it's supposed to look like when it works because I made up the entire concept, and the whole thing is built on top of piles of arcane templated serialization and remote procedure calls. But it finally works now! ...probably. #coding #worldfabric #cplusplus #networkCoding

The experimental #NetworkCoding feature in @batadv is queued for removal (unless someone steps up to put a considerable amount of work into it?): https://lists.open-mesh.org/mailman3/hyperkitty/list/[email protected]/thread/F7L4X2LHMWPTNPYLMZDWDSTSV5ILJ47E/

More details about its design can be found here:

@dentangle @librecast @gstreamer (also, I was told that #NetworkCoding, other than a simple XOR, were a patent mine field... so much regarding no #SoftwarePatents in the #EuropeanUnion...)

@dentangle @librecast after playing with @gstreamer and #RaptorQ I was also wondering, if there were some #NetworkCoding algorithms that could do something like this: For some fixed data X, have n different multicasted streams, with each next one having a twice as high bitrate. The app/library joins the next #multicast stream with double as much bitrate until the path is saturated.
Is it something along that line you're looking for?

My reading for @librecast has arrived!

Much #Matrix #Mathematics and #Multicast to come! 😎

RFC 8975: Network Coding for Satellite Systems

Prenons de la hauteur. Les communications via #satellite posent des tas de problèmes techniques. L'envoi de chaque bit coûte cher, et dans certains cas d'usage, les pertes de paquets sont nombreuses, et on cherche donc à optimiser. Ce #RFC explique comment on peut utiliser le #networkCoding pour améliorer les performances de ces liaisons. Mais c'est encore un travail en cours.
