Abstract
A first network device may receive packets as part of a traffic flow of an internet protocol session, select a packet based on a rule, and add, to a packet replica of the selected packet, routing information capable of being used to generate performance indicators associated with the IP session. The first network device may modify a portion of the packet replica to include values that will cause the packet replica to fail to reach a destination device associated with the IP session, and provide the packet replica to other network devices to cause a second network device to perform a validation procedure to determine that the packet replica is unable to be validated based on the values, to generate the performance indicators using the packet replica or a group of packet replicas that have been modified, and to provide the performance indicators to a particular device.
