Abstract
In one embodiment, a router located at an exit edge of an autonomous system (AS) receives a data packet in a data plane, and determines a destination of the data packet and an associated AS-path information to the destination. The router may then insert the AS-path information into the data packet, and forwards the data packet with the AS-path information toward the destination, such that a receiving device in a destination AS can validate whether the data packet was routed through a path that was secure from a control plane perspective based on a collection of one or more insertions of AS-path information.
