We aim to understand which networks filter invalid routes and how effective that filtering is in blocking prefix hijacks. ...
Analyzing the effectiveness of RPKI, we find that the current trend to deploy RPKI on routeservers of Internet Exchange Points (IXPs) only provides a localized protection against hijacks but has negligible ...
Our goal is to understand how ROV in different network types affects propagation of invalid paths and how effective ROV deployments are in blocking hijacks. Measurements of ROV. ...
