Brilliant presentation and description. Are these slides available?

[@EchoVids2u]

awesome powerpoint.

[@m2tdev]

thanks

[@lulewis2437]

are these slides available? quite an inspiring one!

[@lecardinal1]

about connectivity framework slide (at 4'44), do the blue boxes are the applications of the presented system ? In such system (autonomous vehicle), may i ask how many DDS domains are existing ?

Is this not just reinventing the wheel in the application layer above UDP? TCP does exactly this. Why not use UDP broadcast to share topics and their associated TCP addresses, and let TCP handle the reliability?

[@meatgoat4084]

For the same reason that developers have been adding reliability and QoS layers on top of UDP for at least 30 years. TCP is undesirable for low latency applications and in fact is full of artificial latencies by design such as slow start, congestion windows and Nagling. The question should be after all this time why hasn't there been a widely accepted standard protocol that sits between UDP and TCP to fill this niche?
By the way, thank goodness wheels are constantly being reinvented. My Tesla would look ridiculous rolling down the street on tree logs.
