Abstract
In general, one aspect, the disclosure relates to a method for sampling packets in a network. The method includes receiving, by a first network device, a packet, making a first determination, by the first network device, that the packet is to be sampled, in response to the first determination: sampling the packet to obtain sampling data, storing sampling metadata associated with the packet, encapsulating, after the sampling, the packet to obtain an encapsulated packet, where the encapsulated packet comprises a bit that is set in an encapsulation header, wherein the bit is set based on the presence of the sampling metadata, and transmitting the encapsulated packet to a second network device.
