Hehh.. As you well know, there are many folks that invest
enormous time and money into this, and yet realize, that ultimately,
there are influencers in the routing system and data path between
the client and the service node that the service operators can't

It enables visibility and transparency which can be employed to
inform measurement and detection systems. IF / how an operator
chooses to apply controls based on that information (e.g., drop
