In one embodiment, one packet each is received from a first and a second network device. The time stamps of these packets are recorded in a set of ingress time stamps and a set of egress time stamps respectively if the first and second network devices are the ingress and egress network devices of a traffic flow and if both packets include indications for delay measurement. Then the method continues with a delay measure for the traffic flow based on at least the sets of the ingress time stamps and egress time stamps associated with the flow identifier of the traffic flow, and a measurement noise the electronic device obtained from sending measurement packets to the first and second network devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for delay measurement of a traffic flow in a software-defined networking (SDN) system","description":"Methods for delay measurement in a software-defined networking (SDN) system are disclosed.
