The method includes transmitting request messages to at least one first network node, the request messages each including at least a sampling time-window and a network slice identifier, the sampling time-window defining a duration of time, the network slice identifier identifying a designated network slice within the communication network, receiving packet reports from the at least one first network node, the packet reports including latency information for packets that are processed by the at least one first network node during the sampling time-window for the designated network slice, and controlling the operation of the communication network based on the latency information.
