Abstract:
A method for operating a source node includes receiving a data path validation request command requesting validation of a path associated with a traffic flow identified in the data path validation request command, and determining a first hop sequence in accordance with the path being validated, wherein the first hop sequence is identical to a second hop sequence associated with a non-validation request packet associated with the path being validated. The method also includes generating, by the source node, a validation request packet in accordance with the data path validation request command, the validation request packet comprises route information associated with the first hop sequence, an alert flag set to a specified value, and a path validation header specifying processing performed by nodes receiving the validation request packet, and transmitting, by the source node, the validation request packet in accordance with the route information.
