Abstract
In one embodiment, a plurality of packets is sent from an origin device along a communication path toward a destination device. Each packet includes a lifespan indicator which is incrementally increased for each subsequently sent packet. A plurality of response messages are received at the origin device from a plurality of intermediate devices, respectively. A plurality of secure path objects included in the plurality of response messages, respectively, is determined. Additionally, the plurality of secure path objects are validated based on validation information accessible by the origin device. Validation results of the plurality of secure path objects are checked to determine whether a packet that is sent from the origin device and received by the destination device travels along a particular communication path as dictated by control plane information.
