Re: Internet failures over the next 3 years

There have been a number of suggestions for in-band (i.e. within BGP or at least within router) authentication. I have not yet seen one with no disadvantages.

Nor should you expect one without disadvantages. There is a clear tradeoff here between the quality of the authentication and the computational complexity. Some leadership is needed in the ISP community to put a stake in the ground and at least experiment with one of the alternatives. Tony
