&gt; That&#x27;s not how BGP works.<p>Of course not. I only stated what Fastly needs, I did not make a statement about how BGP works.<p>By having full BGP feeds from all transit providers the nodes can use the AS paths as part of the heuristics to determine the best possible path (with the available information) from first packet. Obviously the heuristics will also use after the fact probe information to tune the model.<p>The point is that the solution proposed by the grandparent is not better than the one described in the article.<p>&gt; There is nothing in this article that talks about optimization of routes.<p>No, they talk about route selection.
