Abstract
A network element is disclosed. In accordance with some embodiments of the present disclosure, a network element may comprise a network interface configured to communicatively couple to a network, and a controller communicatively coupled to the network interface. The controller may be configured to determine a delay-measurement interval, and to perform a plurality of delay measurements at a respective plurality of randomly determined times within the delay-measurement interval. Performing a delay measurement may comprise sending an outgoing signal, receiving an incoming signal, and determining a delay time based on the outgoing signal and the incoming signal.
