Abstract
Methods and apparatus for compensating for time-based sampling using packet elimination are disclosed herein. An example method may be implemented in a network device communicatively connected to a network. The method may include: receiving a packet over the network at a monitoring point; replicating the received packet; determining whether to sample the replicated packet using a time-based sampling scheme; upon determining that the replicated packet should be sampled, queuing the replicated packet to a port of the network device; determining whether to eliminate the queued packet by comparing a configured sample rate with a current sample rate; upon determining that the current sample rate is less than the configured sample rate, exporting the queued packet from the network device; and upon determining that the current sample rate is greater than or equal to the configured sample rate, dropping the queued packet.
