One crucial way in which S*BGP differs from other features is that ASes which deploy S*BGP *must* use their ability to validate paths to inform route selection (otherwise, adding security to BGP makes no sense). Therefore, S*BGP is bound to affect how traffic flows on the Internet. Our work is about harnessing this observation to drive S*BGP deployment. We consider the case that security plays a very small role in the BGP decision process and, in particular, that security considerations come *after* the Local-Pref and AS-PATH length steps in the BGP decision process. We give evidence that even in this case a small set of early adopters is sufficient to transition a large fraction of the Internet to S*BGP.
