Matt, I was intrigued by your throwaway &quot;not another multi hop routing protocol&quot; comment. As far as I can tell, the field is very slow-moving. The state of the art, Babel, is at least 5 years old and is an incremental improvement on protocols that are at least 20 years old. Some very promising research was done into DHT-based routing with Scalable Source Routing, but this work is now from more than 10 years ago, and interest seems to have dropped off completely.<p>Are there a bunch of protocols that I don&#x27;t know about?<p>Are you maybe referring also to centralized path finding algorithms? This would explain the comment.
