It's possible we've become accustom to a slow, global BGP, due to a
perception of fragility (and complexity), which favours stability over
speed.

I suppose the size of the current BGP and the nature of the FSM it lends
itself to does some to account for those perceptions.

At a per-ISP level, it is not impossible to speed up (i)BGP convergence.
On a global scale, taking the least common denominator to allow for all
manner of network we don't know about, allowing the ship a wide turn in
BGP waters, at least on a perceptive level, seems like an unsigned
social agreement amongst autonomous systems.

Ultimately, I feel we aren't talking enough about this, and hopefully,
this thread gets us to that point.

Mark.
