> If the source field in a packet reliably indicated the source of the packet and a given IP was sending you a lot of unwanted traffic, you'd ask their ISP to turn them off and the problem would be solved
No. Your email will go straight into trash because ISP is not interested in doing something for people who don't pay them money. Also, even if they cooperate, it will take too much time.
> Null routing is available
Null routing means complying with criminals' demand (they want the site to become inaccessible).
> it's unlikely to happen
It will very likely happen if there will be a serious attack on Western infrastructure: for example, if there will be no electricity in a large city for several days, of if hospitals across the country won't work or something like this. Then the measures will be taken. Of course, while the victims are small non-critical businesses, nobody will care.
> Otherwise, the only solution is to have more input bandwidth than the attack and suck it up. Content networks are in a great position here, because they deliver a lot of traffic over symetric connections, they have a lot of spare inbound capacity.
So until my proposal is implemented the only solution is to pay protection money to unnecessary middlemen like Cloudflare.
