It does not explain why TOR boxes have little buffers and chassis box

I am in the camp of no MD5 in general and more specifically IX. It is a
real pain to manage MD5 and no network in my experience has ever
implemented a sustainable solution. There is no BCP that folks follow so
generally its a verbal agreement that someone in either party will

It is also possible and in fact easy to have enough to accumulate

I'd rather not be in either situation, but in the later I can police my

his core would be cheaper than replacing all the hardware. Not understanding
the topology and the application makes good recommendations a crap
for those who say bufferbloat is a problem, do you have wred enabled on

For *most backbone networks* it is a no-op on the backbone. To be
more precise, if the backbone is at least 10x,
