A method of monitoring packet traffic is provided. The method includes: at a first access point, capturing portions of traffic packets passing therethrough separated by time intervals; encapsulating the portions of traffic packets thereby forming encapsulated packets and adding timestamps to the encapsulated packets so as to preserve the portions of traffic packets and information related to the time intervals; transmitting the encapsulated packets over a network; decapsulating the encapsulated packets so as to obtain replay packets and the capture timestamps, wherein the replay packets include the portions of the traffic packets; and, transmitting the replay packets separated by the time intervals, wherein the timestamps are used to reproduce the time intervals so as to imitate the traffic packets passing through the first access point.
