Deployment Assumptions
IANA and registration authorities will support PKIs
First tier ISPs will implement countermeasures
Lower level ISPs/DSPs/Subscribers may implement
ISPs/DSPs/Subscribers who are running e-BGP will cooperate in the generation and distribution of route attestations
Subscribers (or their providers) will cooperate in the generation/maintenance of address attestations
Auxiliary BGP devices can be deployed without changes to current router hardware or software (and may even improve performance of existing routers)
